 CALIFORNIA DEPARTMENT OF INDUSTRIAL
 RELATIONS,

                    Real Party in Interest and Respondent.

         On August 20, 2016, Martin Mariano, an employee of plaintiff L & S Framing
Inc., was working on a residential house under construction when he fell from the second
floor onto the concrete ground floor below, sustaining serious injuries. Following an
investigation, real party in interest California Department of Industrial Relations’

                                                             1
Division of Occupational Safety and Health (the Division) issued a notice of intent to cite
plaintiff and subsequently issued a citation, which eventually included a serious accident-
related citation for violation of California Code of Regulations, title 8, section 1626,
subdivision (b)(5).1 Plaintiff appealed the citation. An administrative law judge (ALJ)
denied the Division’s mid-hearing request to amend the citation to allege a violation of
section 1632, subdivision (b)(1), denied the Division’s post-hearing motion to amend to
allege violation of section 1626, subdivision (a)(2), and concluded the Division failed to
prove the alleged violation of section 1626, subdivision (b)(5). The Division filed a
petition for reconsideration with the defendant California Occupational Safety and Health
Appeals Board (the Appeals Board). The Appeals Board concluded the ALJ improperly
denied the two requests to amend and upheld the citation based on violation of both
section 1632, subdivision (b)(1) and 1626, subdivision (a)(2). Plaintiff filed a petition for
a writ of mandate in the trial court, the trial court denied the petition, and plaintiff
appeals.
       Plaintiff asserts the trial court (1) erred in permitting the Appeals Board to amend
the citation, (2) incorrectly concluded sections 1632, subdivision (b)(1) and 1626,
subdivision (a)(2) applied, and (3) incorrectly concluded section 1716.2 did not apply and
did not supersede the other regulations on the facts of this case. The second and third of
these contentions depend on the seemingly simple question whether the specific location
from which Mariano fell qualified as a floor opening (§ 1632, subd. (b)(1)) and/or a
stairwell (§ 1626, subd. (a)(2)), or instead an “unprotected side[] or edge[]” (§ 1716.2,
subd. (f)).
       We affirm. We conclude the Appeals Board properly allowed the Division to
amend the citation, the Appeals Board reasonably deemed the location at issue to fall

1Further undesignated citations are to sections in title 8 of the California Code of
Regulations.

                                               2
within the scope of sections 1632 subdivision (b)(1) and 1626, subdivision (a)(2) and that
determination was supported by substantial evidence, and the Appeals Board properly
determined section 1716.2 did not apply.
                                     BACKGROUND
                                        The Accident
       On August 20, 2016, plaintiff’s employees were working in a subdivision called
Highland Grove. Mariano worked for plaintiff and was on the crew working on unit
number 49. At that location, a stairway had been built from the ground floor to the
second floor. The U-shaped stairway consisted of three segments of stairs. The first
segment was to the right as one entered the front door and led part way up from the
ground floor. The second segment turned 90 degrees to the left of the first and continued
upwards. The third again turned 90 degrees to the left and continued upward until it
connected with the second floor. The lowest segment of stairs starting on the ground
floor abutted the wall containing the entry door. As they constructed the stairs, plaintiff’s
employees also built wooden railings. After the floor on the second floor was covered
with plywood decking, but before exterior walls were erected, workers assembled
wooden railings around the open edges.
       At the top of the stairs on the second floor, there was an L-shaped floor space
leading away from the stairs and then perpendicularly 90 degrees to the left. Wooden
railings or handrails on each of the two sides were erected after the flooring was put
down, one along the landing at the stop of the stairs and another extending
perpendicularly to the left for several feet until it met the framing of a wall. But for the
railing extending to the left, the floor would have led into an open space above the
interior area of the house’s ground floor. At least one witness referred to that railing

                                              3
alternately as a railing and a wall.2 Testimony indicated that, at some point, that railing
was to be replaced with, or perhaps completed as, a short interior wall approximately 36
inches high. Once completed, one would be able to see the house’s “volume ceiling”
from the second-floor “bonus room” over that short wall.
       On the day of the accident, Mariano was on the second floor doing wall
installation. The workers removed the railing or handrail that was where the short wall
would ultimately be erected because they were working on an exterior wall which they
had to lay down on the floor of the bonus room in order to work on it. It would not fit on
the floor with the handrail in place.
       Mariano was “chalking the strap line with his back towards the unguarded
stairwell (inaudible) and he fell to the [first] floor.” Mariano fell 10 feet four inches to
the concrete floor on the ground floor below. He sustained a brain injury characterized as
a serious injury.
                                 The Division Issues Citations
       Ronald Aruejo, a senior safety engineer for the Division, issued plaintiff three
general citations and one serious accident-related citation. Only the serious accident-
related citation is at issue here.
       Before issuing the serious accident-related citation, Aruejo sent a notice of intent.
The notice of intent, Cal/OSHA form 1BY (1BY), cited an alleged violation of one of the
Division’s Construction Safety Orders. (§ 1502 et seq.) Specifically, the 1BY alleged a
violation of section 1626, subdivision (a)(2), although it also stated the alleged violation

2 Plaintiff insists this was not a railing but the framing of a short wall, and the fact that
witnesses referred to it as a railing did not convert the skeletal framing of the short wall
into a railing. Whether this structure was a temporary railing or the structural framing for
a short wall ultimately is immaterial. The relevant issues are the definition of the space
where the railing or wall was located and the fact that it was removed, leaving that space
where Mariano fell unguarded.

                                               4
“may be cited as a violation” of that section “or any other applicable regulation.” The
1BY recited, in part: “[T]he employer did not provide railings and toe boards meeting
the requirements of Article 16 around the stairwell of a story [sic] residential building
under construction. As a result, an employee was seriously injured when he fell from the
open side of the stairwell and landed approximately 11 feet below onto a concrete floor.”
       The subsequent citation itself set forth the following: “[T]he employer did not
provide the exposed sides of a stairway with temporary railings and toe board as
prescribed in Section 1620. As a result, an employee was seriously injured when he fell
from the exposed side of the stairway and landed approximately 11 feet below onto a
concrete floor.” The citation cited section 1626, subdivision (a)(5). According to
Aruejo, the language in the citation was from section 1626, subdivision (b)(5), and the
reference to a nonexistent subdivision (a)(5) was a typographical error. The citation sets
forth verbatim the language appearing in section 1626, subdivision (b)(5). That
subdivision provides: “Unprotected sides and edges of stairway landings shall be
provided with railings. Design criteria for railings are prescribed in Section 1620 of these
safety orders.” (§ 1626, subd. (b)(5).)
       Plaintiff appealed the citation. A hearing before an ALJ followed. The hearing
occurred over four days, November 14 and 15, 2017, and September 5 and 6, 2018.
       On the first day of the hearing, the ALJ granted the Division’s request to amend
the citation to refer to section 1626, subdivision (b)(5) rather than nonexistent subdivision
(a)(5). In July 2018, the Division moved to amend the citation to allege, in the
alternative, a violation of section 1632, subdivision (b)(1). That section provides:
“Floor, roof and skylight openings shall be guarded by either temporary railings and
toeboards or by covers.” (§ 1632, subd. (b)(1).) The ALJ denied the motion.
       In its post-hearing brief, the Division again sought to amend the citation, this time
to conform to the evidence and allege violation of section 1626, subdivision (a)(2). That
section provides: “Railings and toeboards meeting the requirements of Article 16 of

                                              5
these safety orders shall be installed around stairwells.” (§ 1626, subd. (a)(2).) The
Division asserted: “[T]he Division’s 1BY notice cited [plaintiff] for a violation of
section 1626[, subdivision](a)(2) and [plaintiff] has argued vigorously that the
unprotected edge was not a stairwell. [Citation.] Thus, [plaintiff] had an opportunity to
defend itself against this allegation and cannot claim surprise.” The Division also argued
the 15-foot trigger height for fall protection in section 1716.2 did not apply to interior
unprotected sides and edges.
                                 The ALJ’s Determination
       The ALJ determined the Division failed to establish plaintiff violated section
1626, subdivision (b)(5), finding that section inapplicable to the circumstances.
Accordingly, the ALJ dismissed the citation and vacated the penalty. The ALJ also
denied the Division’s post-hearing request to amend the citation to conform to the proof
and to allege a violation of section 1626, subdivision (a)(2).
                   The Appeals Board’s Decision After Reconsideration
       The Division filed a petition for reconsideration with the Appeals Board. Among
the enumerated issues to be presented, the Division included: [¶] “Was the unguarded
side from which Mariano fell the side of a stairway landing?”; [¶] “Was the unguarded
side from which Mariano fell the side of a stairwell?”; [¶] “Was the unguarded side from
which Mariano fell a floor opening?”; [¶] “Did the ALJ abuse her discretion in denying
the Division’s motion to amend Citation 2, Item 1 brought 41 days before the date of the
continued hearing?”; and “Did the ALJ abuse her discretion in declining to amend under
§ 386?”
       Plaintiff filed an answer to the Division’s petition for reconsideration. Among
other things, plaintiff asserted the Division should not be permitted to amend to allege
additional violations, particularly after commencement of the hearing. Plaintiff also
argued the location from which Mariano fell was neither a floor opening nor a stairwell.
While plaintiff had notice the Division challenged both the ALJ’s denial of its requests to

                                              6
amend and the merits of the proposed amendments, plaintiff did not seek leave to reopen
the hearing or present additional evidence.
       In its decision after reconsideration, the Appeals Board upheld Citation 2 as
amended. The Appeals Board agreed with the ALJ that the area from which Mariano fell
was not a stairway landing and therefore concluded plaintiff did not violate section 1626,
subdivision (b)(5), which served as the original basis for Citation 2 after it was amended
by the ALJ to correct the typographical error.
       However, the Appeals Board concluded the ALJ erred in denying the Division’s
mid-hearing motion to amend Citation 2 to plead in the alternative a violation of section
1632, subdivision (b)(1). The Appeals Board concluded plaintiff failed to demonstrate
prejudice. Resorting to dictionary definitions of the term “opening” (§ 1632, subd. (b)(1)
[“Floor, roof and skylight openings shall be guarded by either temporary railings and
toeboards or by covers”]), the Appeals Board concluded Mariano fell through what could
be characterized as a floor opening which was unguarded and unprotected in violation of
section 1632, subdivision (b)(1). Therefore, the Appeals Board overruled the ALJ,
granted the motion to amend, and upheld the violation on this basis.
       The Appeals Board further concluded the ALJ erred in denying the Division’s
post-hearing motion to amend.3 The Appeals Board concluded there was no evidence of

3 For the first time in its reply brief, plaintiff contends the Appeals Board’s analysis as to
amendment was erroneous because it concluded the ALJ erred in denying amendment,
whereas the proper standard is abuse of discretion. “ ‘ “Obvious considerations of
fairness in argument demand that the appellant present all . . . points in the opening brief.
To withhold a point until the closing brief would deprive the respondent of [the]
opportunity to answer it or require the effort and delay of an additional brief by
permission. Hence the rule is that points raised in the reply brief for the first time will
not be considered, unless good reason is shown for failure to present them before.” ’ ”
(Reichardt v. Hoffman (1997) 52 Cal.App.4th 754, 764, quoting Neighbours v. Buzz
Oates Enterprises (1990) 217 Cal.App.3d 325, 335, fn. 8; accord, Allen v. City of

                                              7
bad faith. The Appeals Board acknowledged the failure to cure a deficiency “at prior
allowances to amend” could be deemed to weigh in plaintiff’s favor. The Appeals Board
found plaintiff failed to demonstrate prejudice, and further overruled its own prior case
law to the extent it could be read as suggesting undue delay alone may be sufficient to
warrant denial of a motion to amend. Finally, the Appeals Board found that the ALJ
erred in concluding that the amendment would have been futile. In addressing the merits
of the amendment, the Appeals Board found plaintiff’s definition of “stairwell,” derived
from the Construction Dictionary, to be too narrow, noting that other dictionaries defined
the term more broadly. The Appeals Board also emphasized that the Occupational Safety
and Health Act of 1973 was enacted “for the purpose of assuring safe and healthful
working conditions for all California workers.” The Appeals Board accepted the
Division’s broader definition of the term stairwell. Having found the location from
which Mariano fell constituted a stairwell, the Appeals Board granted amendment and
further upheld the violation on this basis as well.4
                   Denial of Petition for a Writ of Mandate and Appeal
       Plaintiff filed a petition for a writ of mandate pursuant to Code of Civil Procedure
section 1094.5 in the trial court, seeking to have the Appeals Board’s decision after
reconsideration set aside. After oral argument, the trial court denied the petition.
Plaintiff timely appealed.

Sacramento (2015) 234 Cal.App.4th 41, 52.) In the absence of any showing of good
cause, we decline to address this contention.
4 We note that, the Appeals Board having granted the post-hearing motion to amend,
Citation 2 thus included an allegation of violation of section 1626, subdivision (a)(2),
mirroring the Division’s original 1BY notice of intent.

                                  Request for Judicial Notice
       The Appeals Board filed a motion requesting that we take judicial notice of
Appeals Board decisions appended to its motion. The decision on the request for judicial
notice was deferred pending calendaring and assignment of the panel.
       The Appeals Board’s decisions after reconsideration are precedential; they
establish the Appeals Board’s official policy. (Davey Tree Surgery Co. v. Occupational
Safety & Health Appeals Bd. (1985) 167 Cal.App.3d 1232, 1243 [Board counters that
cases cited by appellant were decided by ALJs and were not, with exceptions, reviewed
by Board, the decisions of which after reconsideration establish official Board policy].)
The trial court considered a number of these decisions in its order denying plaintiff’s
petition for a writ of mandate.
       We grant the Appeals Board’s unopposed request for judicial notice. (Evid. Code,
§§ 452, subd. (c), 459.)
       Plaintiff also cites to the Appeals Board decisions in its briefing, including
decisions not the subject of the Appeals Board’s request for judicial notice, but plaintiff
did not file a request for judicial notice of its own. We note California courts routinely
cite Appeals Board decisions. (See, e.g., Elsner v. Uveges (2004) 34 Cal.4th 915, 930;
Rick’s Electric, Inc. v. Occupational Safety & Health Appeals Bd. (2000) 80 Cal.App.4th
1023, 1034, 1037; Overaa Construction v. California Occupational Safety & Health
Appeals Bd. (2007) 147 Cal.App.4th 235, 241, 247, fn. 18 (Overaa Construction); Davey
Tree Surgery Co. v. Occupational Safety & Health Appeals Bd., supra, 167 Cal.App.3d at
pp. 1241-1242.) We further note that, as a reviewing court, we “shall take judicial notice
of . . . each matter properly noticed by the trial court . . . .” (Evid. Code, § 459, subd.
(a).) While the better practice would have been for plaintiff to file its own request for

                                               9
judicial notice, on our own motion, we take judicial notice of all Appeals Board decisions
cited by the parties. (Evid. Code, §§ 452, subd. (c), 459, subd. (a).)
                                              II
                                     Standard of Review
       The review by a court considering a petition for a writ of mandate challenging an
Appeals Board decision “shall not be extended further than to determine, based upon the
entire record which shall be certified by the appeals board, whether: [¶] (a) The appeals
board acted without or in excess of its powers. [¶] (b) The order or decision was
procured by fraud. [¶] (c) The order or decision was unreasonable. [¶] (d) The order or
decision was not supported by substantial evidence. [¶] (e) If findings of fact are made,
such findings of fact support the order or decision under review. [¶] Nothing in this
section shall permit the court to hold a trial de novo, to take evidence, or to exercise its
independent judgment on the evidence.” (Lab. Code, § 6629; see Overaa Construction,
supra, 147 Cal.App.4th at p. 245.) “The findings and conclusions of the appeals board on
questions of fact are conclusive and final and are not subject to review. Such questions
of fact shall include ultimate facts and the findings and conclusions of the appeals board.”
(Lab. Code, § 6630.)
       “ ‘ “Our function on appeal is the same as that of the trial court in ruling on the
petition for the writ. We must determine whether based on the entire record the
[Appeals] Board’s decision is supported by substantial evidence and whether it is
reasonable. [Citations.] Where the decision involves the interpretation and application of
existing regulations, we must determine whether the administrative agency applied the
proper legal standard. [Citation.] Since the interpretation of a regulation is a question of
law, while the administrative agency’s interpretation is entitled to great weight, the
ultimate resolution of the legal question rests with the courts . . . . An agency’s expertise
with regard to a statute or regulation it is charged with enforcing entitles its interpretation
of the statute or regulation to be given great weight unless it is clearly erroneous or

                                              10
unauthorized. [Citations.] The [Appeals] Board is one of those agencies whose expertise
we must respect. [Citation.]” [Citation.] However, “[a]n administrative agency cannot
alter or enlarge the legislation, and an erroneous administrative construction does not
govern the court’s interpretation of the statute.” ’ ” (Overaa Construction, supra,
147 Cal.App.4th at pp. 244-245.)

                                  Amendment of Citation
A.     Plaintiff’s Contentions
       Plaintiff asserts the trial court erred in permitting the Appeals Board to amend the
citation. Plaintiff asserts the Appeals Board ultimately found a violation based on two
regulations that were not correctly pled. According to plaintiff, in doing so, the Appeals
Board created exceptions to Labor Code sections 6317 and 6432 and thus engaged in
“underground regulation” by creating a definition for a regulatory term without
complying with the Administrative Procedure Act (Gov. Code, § 11340 et seq.). Plaintiff
challenges (1) the Division’s ability to plead more than one violation in the alternative,
(2) the mid-hearing amendment, and (3) the post-submission amendment.
B.     Authority for Amendments Generally
       The Labor Code provides that the “rules of practice and procedure adopted by the
appeals board shall be consistent with,” among other things, Government Code section
11507. (Lab. Code, § 6603.) Government Code section 11507 provides, in part: “At any
time before the matter is submitted for decision, the agency may file, or permit the filing
of, an amended or supplemental accusation . . . .” Thus, Government Code section 11507
contemplates amendments to accusations, and, pursuant to Labor Code section 6603, the
rules of practice adopted by the Appeals Board shall be consistent with that provision.
       Section 371.2, a “rule[] of practice and procedure adopted by the appeals board”
(Lab. Code, § 6603), expressly addresses amendments of a citation or appeal. Among
other things, it provides that a “request for an amendment that does not cause prejudice to

                                             11
any party may be made by a party or the Appeals Board at any time.” (§ 371.2, subd.
(a)(1).)
       Labor Code section 6603 also requires the “rules of practice and procedure
adopted by the appeals board” to be consistent with Government Code section 11516.
That section authorizes amendment of an accusation “after submission of the case for
decision.” (Gov. Code, § 11516.)
       Section 386, subdivision (a) provides: “The Appeals Board may amend the issues
on appeal or the Division action after a proceeding is submitted for decision.” Thus, as a
general matter, post-submission amendments are authorized. In fact, “amendments at
trial to conform to proof, ‘if not prejudicial, are favored since their purpose is to do
justice and avoid further useless litigation.’ ” (Garcia v. Roberts (2009) 173 Cal.App.4th
900, 909.)
C.     Pleading in the Alternative
       Plaintiff asserts pleading multiple, alternative violations is prohibited under the
Labor Code. Contrary to plaintiff’s contentions, the Division has the option to plead in
the alternative. (MTM Builders, Inc. (Cal. OSHA, June 12, 2020, No. 1101230) 2020 CA
OSHA App.Bd. Lexis 78, at p. *5 [“the Division failed to exercise its option, which it has
exercised in numerous other instances, effectively to plead in the alternative”].) This is
consistent with the modern practice in courts. (See Mendoza v. Continental Sales Co.
(2006) 140 Cal.App.4th 1395, 1402 [“When a pleader is in doubt about what actually
occurred or what can be established by the evidence, the modern practice allows that
party to plead in the alternative and make inconsistent allegations”].)
       Allowing pleading in the alternative is also consistent with interpretation of the
federal Occupational Safety and Health Act. (See Alcala v. Western Ag Enterprises
(1986) 182 Cal.App.3d 546, 550 [“It has been held that when California’s laws are
patterned on federal statutes, federal cases construing those federal statutes may be
looked to for persuasive guidance”]; see also Lujan v. Minagar (2004) 124 Cal.App.4th

                                              12
1040, 1045 [Cal-OSHA is patterned after federal counterpart].) As the Ninth Circuit
stated concerning alternative pleading in OSHA cases: “Nor does pleading in the
alternative render the amended complaint insufficiently particular. . . . It helps avoid
complications or delays which are contrary to the goal of fair and speedy enforcement of
the Act.” (Donovan v. Royal Logging Co. (9th Cir. 1981) 645 F.2d 822, 828-829.)
       Plaintiff asserts the Appeals Board in permitting alternative allegations created
exceptions to Labor Code section 6317 and thus engaged in under underground
regulation. Plaintiff relies on the language of that section providing that “[e]ach citation
shall be in writing and shall describe with particularity the nature of the violation,
including a reference to the provision of the code, standard, rule, regulation, or order
alleged to have been violated,” emphasizing that “citation” and “provision” appear in the
singular form.
       Labor Code section 6317 does not address, or prohibit, amendment of citations.
And, as addressed above, pleading in the alternative is permitted. (MTM Builders, Inc.,
supra, 2020 CA OSHA App.Bd. Lexis 78.) Additionally, as the Appeals Board notes, in
construing the Labor Code, “[t]he singular number includes the plural, and the plural the
singular.” (Lab. Code, § 13.)
       Nor are we persuaded by plaintiff’s reliance on Labor Code section 6432.
Subdivision (b)(2) of that section provides, in part: “The division shall satisfy its
requirement to determine and consider the facts specified in paragraph (1) if, not less than
15 days prior to issuing a citation for a serious violation, the division delivers to the
employer a standardized form containing the alleged violation descriptions (‘AVD’) it
intends to cite as serious and clearly soliciting the information specified in this
subdivision.” We do not find anything in this section 6432 that would prohibit
amendment or pleading in the alternative. Moreover, that section contains an express
provision providing: “The trier of fact may also draw a negative inference from factual
information offered at the hearing by the division that is inconsistent with factual

                                              13
information provided to the employer pursuant to subdivision (b), or from a failure by the
division to provide the form setting forth the descriptions of the alleged violation and
soliciting information pursuant to subdivision (b).” (Lab. Code, § 6432, subd. (d).) That
subdivision does not provide the Division is barred outright from offering inconsistent
factual information or failing to provide the form setting forth the alleged violation; it
provides the option of drawing a negative inference against the Division under such
circumstances. And we note the factual allegations asserted here always remained the
same.
D.      Mid-hearing Amendment
        “[A]mendments to pleadings in the administrative hearing context are liberally
allowed.” (Calstrip Steel Corporation (Cal. OSHA, June 30, 2017, Nos. 12-R3D6-1998,
1999) 2017 CA OSHA App.Bd. Lexis 66 at p. *15.) “A request for an amendment that
does not cause prejudice to any party may be made by a party or the Appeals Board at
any time.” (§ 371.2, subd. (a)(1).) “When considering a request to amend, courts, and
the Board, will examine bad faith of the parties, failure to cure deficiencies at prior
allowances to amend, the futility of an amendment, and prejudice.” (Calstrip Steel
Corporation, supra, 2017 CA OSHA App.Bd. Lexis 66 at pp. *16-17.) “As to a claim of
prejudice, the showing must demonstrate that the party was ‘unfairly disadvantaged or
deprived of the opportunity to present facts or evidence which it would have offered had
the . . . amendments been timely.’ ” (Calstrip Steel Corporation, supra, 2017 CA OSHA
App.Bd. Lexis 66 at p. *17, quoting Dole v. Arco Chemical Co. (3d Cir. 1990) 921 F.2d
484, 488.) “Prejudice will not be presumed but must be affirmatively demonstrated
through production of evidence.” (Sierra Forest Products (Cal. OSHA, Apr. 8, 2016,
No. 09-R2D5-3979) 2016 CA OSHA App.Bd. Lexis 28 at p. *7.)
        There is no indication of bad faith in the record or any specific allegations in
plaintiff’s briefs. Nor do the parties address in any substantive way the failure to cure
deficiencies at prior allowances to amend.

                                              14
       With regard to prejudice, plaintiff asserted it had been denied notice of the
violation because the citation “did not reference any indication of a charged violation of
. . . [section] 1632[, subdivision ](b)(1),” and there was “no indication that [plaintiff] had
failed to guard a ‘floor opening’ in violation of” that section, and did not reference any
“floor opening.” As a result, plaintiff asserted it was “too late to prepare a defense.”
Plaintiff also emphasized the passage of time since the accident and the fact that
discovery had been completed. According to plaintiff, all of its resources had gone
towards investigating and defending against the original citation, and plaintiff further
asserted it would be required to expend more resources to develop a defense against an
amended citation. In this regard, plaintiff emphasized faded memories of witnesses and
witness unavailability.
       As the Appeals Board notes, the proposed amendment did not seek to change the
factual description of the alleged violation. Instead, it sought to plead, in the alternative
and based on all of the same facts, that plaintiff failed to protect the sides and edges of a
“stairway landing[]” (§ 1626, subd. (b)(5)), and, through the amendment, that plaintiff
failed to guard a “[f]loor . . . opening[]” (§ 1632, subd. (b)(1)). In other words, through
the amendment, and based on all of the same facts, the Division sought to proceed
pursuant to the theory that the removal of the railing resulted in an unprotected stairway
landing, or, in the alternative, on the theory that it resulted in an unguarded floor opening.
With regard to amending a pleading, “[i]f the same set of facts supports merely a
different theory . . . no prejudice can result.” (Garcia v. Roberts, supra, 173 Cal.App.4th
at p. 910.) We conclude plaintiff failed to establish it would be prejudiced by this
amendment.
       Finally, as for futility, we conclude, post, that the Appeals Board properly found a
violation of section 1632, subdivision (b)(1). As such, it cannot be said that amendment
to add a violation of that section would have been futile.

                                              15
E.     Post-submission Amendment
       Considering the same factors addressed in part II.D as to the request to amend
post-submission pursuant to section 386 to allege a violation of section 1626, subdivision
(a)(2), we first note, again, there is no indication of bad faith and plaintiff does not assert
there is. And again, the parties do not address failure to cure deficiencies at prior
allowances to amend.
       Moreover, under the heading addressed to amendment of the citation, plaintiff
does not advance a substantive argument addressing prejudice beyond emphasizing the
passage of time. Instead, plaintiff largely recites the procedural background and argues
amendment was statutorily prohibited and amendment to plead in the alternative should
not be permitted. Plaintiff also emphasizes the consequences of having a serious
violation on its record, which is not germane to prejudice in the context of whether
amendment should be granted. Plaintiff in its opening brief only mentions prejudice once
in quoting the ALJ and a second time in asserting, in conclusory fashion, that, “[b]y
definition, the [Appeals] Board’s finding prejudiced” plaintiff.5
       Particularly in the context of a post-hearing request to amend to conform to the
proof, the proposed amendment necessarily did not involve any different facts. Instead, it
sought to prove a violation that plaintiff failed to install, or keep installed under the

5 Plaintiff asserts the Appeals Board held that plaintiff “did not disprove the violations it
found, and that they were ‘fully litigated,’ ” and contends the Appeals Board “essentially
reversed the burden of proof.” It is not clear to what portion of the Appeals Board
decision after reconsideration plaintiff is referring because plaintiff has not provided a
record citation. The Appeals Board stated the “Division proved Employer violated
Citation 2, Item 1 based on both section 1632, subdivision (b), and section 1626,
subdivision (a)(2).” In any event, plaintiff does not make this claim under separate
heading or subheading, does not cite to the record, and does not cite any authority beyond
that standing for the general proposition that the Division bears the burden of proof. (See
Cal. Rules of Court, rule 8.204(a)(1)(B).) Accordingly, we need not address this
contention further.

                                              16
circumstances here, a railing or toeboard around a stairwell (§ 1626, subd. (a)(2)) as an
alternative to the theory that plaintiff failed to protect the sides and edges of a stairway
landing (§ 1626, subd. (b)(5)). In its opening statement, the Division addressed
stairwells, landings, and floor openings. Plaintiff countered by stating there was no
stairwell involved. The parties argued the correct interpretation of stairwell. There was
testimony specifically about the use of the term stairwell, whether a witness would
consider a particular area to be a stairwell, and definitions of the term stairwell.
Plaintiff’s attorney stated at the hearing that “the stairwell and the edge of the stairwell
and a stairway have particular meanings that are critical to this case.” Plaintiff’s counsel
later stated the “issue was whether or not this is the railing that’s shown as number four
[in] the Division’s [photographic] Exhibit 3 is actually part of the stairwell or the
stairway.” We conclude there was no indication of prejudice from this issue involving a
theory that was actually litigated. (Sierra Forest Products, supra, 2016 CA OSHA
App.Bd. Lexis 28 at. p. *7, quoting Conolley v. Bull (1968) 258 Cal.App.2d 183, 193
[“ ‘It is established . . . that if a case is actually tried on the theory which is later added by
an amendment to the pleadings, the adverse party suffers no prejudice from the
variance’ ”].)
       Lastly, because we conclude, post, the Appeals Board properly found a violation
of section 1626, subdivision (a)(2), it cannot be said the post-hearing amendment to
conform the pleading to the proof would have been futile.
                                               IV
     Applicability of Sections 1626, Subdivision (a)(2) and 1632, Subdivision (b)(1)
A.     Plaintiff’s Contentions
       Plaintiff asserts the sections under which the Appeals Board, and the trial court,
upheld violations, sections 1626, subdivision (a)(2) and 1632, subdivision (b)(1), did not
apply to where Mariano fell, “the edge of the bonus room’s floor . . . .” Plaintiff asserts
the Appeals Board “created an ambiguity in the regulations by erroneously concluding

                                               17
that the bonus room floor edge was a ‘stairwell.’ ” Plaintiff argues the Appeals Board
and the Division incorrectly deemed the perimeter edge of the bonus room to be a floor
opening through which someone could fall. As will be discussed in greater detail post
and in part V of the Discussion, plaintiff asserts section 1716.2, subdivision (f) is the
applicable regulation. That regulation requires fall protection “around all unprotected
sides or edges” for work performed on floors that will later be enclosed by framed
exterior walls, but only when the work is performed more than 15 feet above the floor
level below. (§ 1716.2, subd. (f).) The fall here was less than 11 feet to the concrete
floor below.
       Ultimately, the question presented is straightforward, even if the answer to that
question is less so: Did the location from which Mariano fell constitute a stairwell within
the meaning of section 1626, subdivision (a)(2) and/or a floor opening within the
meaning of section 1632, subdivision (b)(1)? We conclude it did on both counts.
B.     Regulatory Interpretation and Substantial Evidence
       “ ‘The interpretation of a regulation, like the interpretation of a statute, is, of
course, a question of law’ and is therefore subject to our de novo review. [Citation.]
Accordingly, while an administrative agency’s interpretation of its own regulation is
entitled to deference appropriate to the circumstances, ‘the ultimate resolution of such
legal questions rests with the courts.’ [Citations.] When interpreting an administrative
regulation, we follow the same rules of construction that apply to statutes. [Citation.]
Thus, our fundamental objective is to ascertain and effectuate the intent of the agency
issuing the regulation. [Citations.] [¶] In determining the issuing agency’s intent, we
look first to the language of the regulation itself. [Citation.] ‘ “If the language is clear
and unambiguous there is no need for construction, nor is it necessary to resort to indicia
of the intent of the [agency] . . . .” [Citation.] “But the ‘plain meaning’ rule does not
prohibit a court from determining whether the literal meaning of a [regulation] comports
with its purpose . . . .” [Citation.] Furthermore, “ ‘where a word of common usage has

                                               18
more than one meaning, the one which will best attain the purposes of the [regulation]
should be adopted, even though the ordinary meaning of the word is thereby enlarged or
restricted and especially in order to avoid absurdity or to prevent injustice.’ ” ’
[Citations.] Moreover, ‘[w]e do not construe a regulation in isolation, but instead read it
with reference to the scheme of law of which it is a part, so that the whole may be
harmonized and retain effectiveness.’ [Citations.] Finally, when an examination of
regulatory language in its proper context fails to resolve an ambiguity, courts may ‘turn
to the [regulatory] history of an enactment as an aid to its interpretation.’ ” (Department
of Industrial Relations v. Occupational Safety & Health Appeals Bd. (2018)
26 Cal.App.5th 93, 100-101 (Department of Industrial Relations).)
       As stated ante, “ ‘ “[a]n agency’s expertise with regard to a statute or regulation it
is charged with enforcing entitles its interpretation of the statute or regulation to be given
great weight unless it is clearly erroneous or unauthorized. [Citations.] The [Appeals]
Board is one of those agencies whose expertise we must respect.” ’ ” (Overaa
Construction, supra, 147 Cal.App.4th at pp. 244-245.)
       “On appeal we must resolve evidentiary conflicts in favor of the prevailing party,
and view the evidence, drawing all reasonable inferences, in the light most favorable to
[the prevailing party]. So long as the whole record so viewed reveals in support of the
judgment evidence of ponderable legal significance, i.e., evidence which is reasonable,
credible, and of solid value, we must affirm.” 6 (Gaehwiler v. Occupational Safety &
Health Appeals Bd. (1983) 141 Cal.App.3d 1041, 1045, fn. 2.)

6 The Appeals Board asserts plaintiff waived any substantial evidence challenge. “ ‘An
appellant challenging the sufficiency of the evidence to support the judgment must cite
the evidence in the record supporting the judgment and explain why such evidence is
insufficient as a matter of law.’ [Citation.] Failure to discuss contrary evidence waives
any argument the judgment is not supported by substantial evidence.” (Antelope Valley
Groundwater Cases (2021) 63 Cal.App.5th 17, 53, fn. 16.) Even if we could deem a

                                              19
C.     Section 1632, Subdivision (b)(1)
       Again, section 1632, subdivision (b)(1) provides: “Floor, roof and skylight
openings shall be guarded by either temporary railings and toeboards or by covers.”
Section 1632 does not define the term “floor opening,” and no such definition appears in
section 1504, the relevant definitions section. Section 1504 does define the term
“[o]pening” as an “opening in any floor or platform, 12 inches or more in the least
horizontal dimension. It includes: stairway floor openings, ladderway floor openings,
hatchways and chute floor openings.” (§ 1504.) The Appeals Board found this definition
ambiguous and resorted to dictionary definitions of the term “opening.” (See Wasatch
Property Management v. Degrate (2005) 35 Cal.4th 1111, 1121-1122 [“When attempting
to ascertain the ordinary, usual meaning of a word, courts appropriately refer to the
dictionary definition of that word”]; Hammond v. Agran (1999) 76 Cal.App.4th 1181,
1189 [“in the absence of specifically defined meaning, a court looks to the plain meaning
of a word as understood by the ordinary person, which would typically be a dictionary
definition”].)
       The dictionary definitions of “opening” upon which the Appeals Board relied
included “a hole or empty space through which things or people can pass” (Collins Dict.
Online  [as of June
22, 2023], archived at: ); “a hole or space that something
or someone can pass through” (Cambridge Dict. Online <
https://dictionary.cambridge.org/us/dictionary/english/opening> [as of June 22, 2023],
archived at: < https://perma.cc/Z7Y3-8ELE >); and “a void in solid matter; a gap, hole,
or aperture” (Dictionary.com  [as of June
22, 2023], archived at: ).

substantial evidence challenge forfeited, we address plaintiff’s contentions on their
merits. (See ibid.)

                                            20
       The Appeals Board then concluded that, when plaintiff’s workers removed the
railing, they “create[ed] a hole or empty space from which people or things could fall
through.” The Appeals Board continued: “Mariano fell through the opening, which was
unguarded and unprotected contrary to section 1632, subdivision (b)(1)’s mandate.” (Fn.
omitted.)
       We conclude the Appeals Board’s construction and interpretation of section 1632,
subdivision (b)(1) comports with the plain meaning of the terms used in that provision.
Specifically, in our de novo review of the interpretation of the regulation (see Department
of Industrial Relations, supra, 26 Cal.App.5th at p. 100), we agree with the construction
of the term opening utilized by the Appeals Board, informed by dictionary definitions.
       As for the evidence supporting the violation of that section, we have reviewed the
hearing testimony. We have also examined the photographic exhibits depicting the site
of the accident. At the top of the stairs on the second floor of the house where the
accident occurred, an L-shaped floor space led away from the stairs and then
perpendicularly to the left. Wooden railings or handrails on each of the two sides were
erected after the flooring was put down, one along the landing at the stop of the stairs and
another extending to the left for several feet until it met the framing of a wall. But for the
railing to the left of and perpendicular to the topmost group of stairs, the floor would
have led into open space above the ground floor. This is the location from which
Mariano fell. Testimony indicated that this railing farther from, and perpendicular to, the
stairs was to be replaced with, or perhaps completed as, a short interior wall
approximately 36 inches high. Once completed, one would be able to see the house’s
“volume ceiling” from the second-floor “bonus room” over that short wall. And, of
course, prior to Mariano’s fall, this railing had been removed.
       We conclude substantial evidence supports the Appeals Board’s determination that
the location from which Mariano fell can be characterized as an unguarded floor opening
within the meaning of section 1632, subdivision (b)(1). Nothing in the definitions

                                             21
utilized by the Appeals Board restricted the concept of a floor opening in such a manner
as to render that term inapplicable to the configuration here. We conclude the Appeals
Board properly upheld the violation under this section.
       We note that, “in the particular context of workplace health and safety here at
issue, our high court has reviewed the statutory structure and—noting that the relevant
provisions ‘speak in the broadest possible terms’—has concluded that ‘the terms of the
legislation are to be given a liberal interpretation for the purpose of achieving a safe
working environment.’ ” (Department of Industrial Relations, supra, 26 Cal.App.5th at
p. 106, quoting Carmona v. Division of Industrial Safety (1975) 13 Cal.3d 303, 312, 313
(Carmona); see also Lab. Code, § 6401 [“Every employer shall furnish and use safety
devices and safeguards, and shall adopt and use practices, means, methods, operations,
and processes which are reasonably adequate to render such employment and place of
employment safe and healthful. Every employer shall do every other thing reasonably
necessary to protect the life, safety, and health of employees.”]; Lab. Code, § 6307 [the
Division “has the power, jurisdiction, and supervision over every employment and place
of employment in this state, which is necessary adequately to enforce and administer all
laws and lawful standards and orders, or special orders requiring such employment and
place of employment to be safe, and requiring the protection of the life, safety, and health
of every employee in such employment or place of employment”].)
       Plaintiff repeatedly criticizes the Appeals Board and the trial court for what it
characterizes as rewriting the regulations, reading into the regulations what the Standards
Board omitted, and engaging in underground regulation. For example, plaintiff maintains
that “[o]nly by distorting the straightforward regulatory language, inserting terms not
included there, and inventing new meanings for construction terminology did the
[Appeals Board] reach untenable conclusions, which the trial court implicitly adopted.”
However, the mere fact that the trial court, and we, disagree with plaintiff’s preferred
interpretation does not mean there has been improper circumventing of the appropriate

                                             22
rulemaking process. It simply means we are persuaded the Appeals Board’s conclusions
are supported by the language of the regulations.
       Plaintiff relies on Cabrillo Economic Development Corp. (Cal. OSHA, Oct. 16,
2014, No. 11-3185) 2014 CA OSHA App.Bd. Lexis 116 (Cabrillo), in asserting the
Appeals Board in that case found that, while section 1632, subdivision (b)(1) applied to
floor openings during framing operations, section 1716.2 applies to unprotected sides and
edges.7 It appears plaintiff’s reliance on Cabrillo is for the premise that where Mariano
fell was not “through” a floor opening like the one described in Cabrillo, but rather over
an edge, such that only section 1716.2, subdivision (f) and its 15-foot trigger height
would apply. We are not persuaded. In Cabrillo, the Appeals Board did determine that
section 1632 applied to the stairwell floor opening through which the employee fell.
(Cabrillo, supra, 2014 CA OSHA App.Bd. Lexis 116 at p. *9.) The Appeals Board
articulated the employee “fell through” the stairway opening in which a stairway would
eventually be installed. (Cabrillo, supra, 2014 CA OSHA App.Bd. Lexis 116 at p. *5 &
fns. 5, 6, 11.) However, while plaintiff would prefer to characterize Mariano’s fall as
over an edge rather than through a floor opening, we are not persuaded that anything in
Cabrillo, including the configuration of that floor opening, establishes the location here
could not also qualify as a floor opening.
       Plaintiff also relies on Webcor Builders, Inc. (Cal. OSHA, Jan. 11, 2010, No. 06-
3030) 2010 CA OSHA App.Bd. Lexis 7. According to plaintiff, the Appeals Board in

7 Subdivision (f) of section 1716.2 provides: “Work on Floors and Other
Walking/Working Surfaces. When working on floors and other walking/working
surfaces that will later be enclosed by framed exterior walls, employees directly involved
with the layout and construction of framed stud walls shall be protected from falling by
standard guardrails as specified in Section 1620 around all unprotected sides or edges, or
by other means prescribed by CSO Article 24, Fall Protection, when the floor or
walking/working surface is over 15 feet above the surrounding grade or floor level
below.”

                                             23
Webcor “held that [section] 1632[, subdivision ](c) – ladderway floor openings or
platforms shall be guarded . . . on all open sides – does not apply to the perimeter of a
building floor because it did not lead to or penetrate a floor and by its terms applies
where there is a danger of employees falling ‘through’ floor openings.” The Appeals
Board in Webcor stated: “By definition, the exterior end or edge of a building’s floor is
not an opening in that floor. Beyond that end or edge there is no floor in which an
‘opening’ can exist. This meaning is reinforced by the language of section 1632[,
subdivision ](a), which is concerned with employees, inter alia, falling through a floor,
not off it, as one would do at the edge.” (Webcor, supra, 2010 CA OSHA App.Bd. Lexis
7 at p. *6.) Elsewhere, the Appeals Board noted of the subject location: “The ladder was
placed on the outside or perimeter of the structure, and thus rested on or connected to the
second floor at the exterior edge of that floor.” (Webcor, supra, 2010 CA OSHA
App.Bd. Lexis 7 at p. *5.) This is distinguishable from the circumstances here, involving
an interior floor edge, or opening.
       We conclude the Appeals Board’s determination was supported by substantial
evidence and was reasonable.
D.     Section 1626, Subdivision (a)(2)
       Section 1626, subdivision (a)(2) provides: “Railings and toeboards meeting the
requirements of Article 16 of these safety orders shall be installed around stairwells.”
Stairwell is not defined in section 1504.
       The location where Mariano was at the time of his fall, the floor next to the
opening over the ground floor, was not at the top of the stairs, but a number of feet to the
side of the top landing of the stairs. According to John Wagner, plaintiff’s witness, there
was no part of the stairway in the area where Mariano landed on the concrete floor. He
estimated the stairs were four to six feet beyond and opposite the wall directly below
where Mariano was situated immediately before he fell. He also testified “the stair
termination is beyond the volume ceiling area, and that vertical housing is limited to the

                                             24
space that the stairs themselves occupy.” Wagner did not consider the area from which
the railing had been removed to be within the stairwell.
       Conversely, Ronald Aruejo, the Division’s witness, testified he considered the
location where Mariano fell to be in the stairwell. Another Division witness, Joel Foss,
testified a stairwell is “the well in which the stairs are.” He also testified he agreed with
an exhibit that had been submitted that provided a dictionary definition of “stairwell.”
That definition, plaintiff’s exhibit T, entitled Construction Dictionary, defined “stairwell”
as “[a] compartment extending vertically through a building in which stairs are placed.”
Foss testified he considered the stairwell to include “the entire space that was described
as the foyer.” Asked why he considered that entire space to be the stairwell, Foss
testified: “Because it’s part of that open space that is unguarded by surrounding walls.
It’s the – it’s part of that open space. It presents the same fall hazard as other areas in
that same open space.” He acknowledged that the space was not limited to the vertical
space directly over the three segments of stairs, but also included “all the other unguarded
sides and edges other than the entry itself, the entry onto the stairs.” Asked again why he
included that area in his conception of the stairwell, whereas Wagner did not, Foss
testified, “[b]ecause that side or edge abuts this same open space, the stairwell, the well
where the stairs are, so it requires guarding.” He again testified he considered the open
area by the railing that was removed, where Mariano fell, to be part of the stairwell and
part of the open area where the stairs were. He testified “[i]t’s all the stairwell.” He
continued: “[T]he stairwell is this open space. It’s not only this pillar of air above the
stairs themselves. It’s the space, the open space, in which the stairwell is situated.” He
testified that, unlike Wagner, he did not conceive of a stairwell as strictly limited to the
area actually occupied by stairs.
       The blueprint, which contained a mirror image of the floorplan, depicted the U-
shaped stairs consisting of three segments beginning on the ground floor. The first

                                              25
segment of stairs did not begin directly under the edge from which Mariano fell, but
several feet opposite that location.
       The Appeals Board in its Decision After Reconsideration considered dictionary
definitions of “stairwell” other than that submitted by plaintiff, including “a long, vertical
passage through a building around which a set of stairs is built” (Cambridge Dict. Online
 [as of June 27, 2023],
archived at: ); and “the vertical shaft or opening
containing a stairway” (Dictionary.com 
[as of June 27, 2023], archived at: .) The Appeals
Board stated plaintiff’s “definition of stairwell, which is supported by the Construction
Dictionary, is too narrow an interpretation of the term since other dictionaries define
stairwell more broadly as a vertical shaft or opening that contains the stairway.” In
connection with this observation, the Appeals Board relied on the California Supreme
Court’s direction that “the terms of the legislation are to be given a liberal interpretation
for the purpose of achieving a safe working environment.” (Carmona, supra, 13 Cal.3d
at p. 313.) The Appeals Board upheld the violation under section 1626, subdivision
(a)(2) as well.
       The Appeals Board precedents on which plaintiff relies are inapposite. They do
not involve stairwells, which are the subject of section 1626, subdivision (a)(2). Instead,
they involve “stairways” (Davis Brothers Framing, Inc. (Cal. OSHA, Apr. 8, 2010, No.
05-634) 2010 CA OSHA App.Bd. Lexis 46), and “fall protection” (JD2 Incorporated

App.Bd. Lexis 1; Reese Construction Company, A Corp. (Cal. OSHA, Nov. 7, 1980, No.

       We conclude the Appeals Board’s determination that this area could be considered
a stairwell was reasonable and was supported by substantial evidence. It is supported by

                                              26
the Division witnesses’ testimony and exhibits as well as the dictionary definitions upon
which the Appeals Board relied. Moreover, this conclusion finds further support in the
direction that such provisions are construed liberally to provide protection and safety for
workers. (Carmona, supra, 13 Cal.3d at p. 313; Department of Industrial Relations,
supra, 26 Cal.App.5th at p. 106.)
                                               V
                                        Section 1716.2
        Plaintiff asserts it was section 1716.2 that applied. Plaintiff asserts the trial court
erred in affirming the Appeals Board’s findings regarding inapplicability of section
1716.2 because those findings violate tenets of regulatory construction and depart from
the plain meaning of the regulation’s language. According to plaintiff, “[o]nly by
distorting the straightforward regulatory language, inserting terms not included there, and
inventing new meanings for construction terminology did the Respondent reach
untenable conclusions, which the trial court implicitly adopted.” Plaintiff asserts the
Division cannot circumvent the proper rulemaking process by creating its own
interpretation, and doing so constitutes underground regulation.
        The Appeals Board and the Division respond that, contrary to plaintiff’s
contention that section 1716.2 controlled, more than one safety order may apply, and
plaintiff did not show that section 1716.2 was both more specific than and in actual
conflict with the sections under which it found violations such that the provisions could
not be reconciled.
        Section 1716.2, subdivision (f) applies in the context of framing and contains a 15-
foot trigger height, below which the prescribed fall protections do not apply.8 We agree
with the Division’s opinion that this provision gives rise to ambiguity as to whether it

8   See footnote 10, ante.

                                               27
“applies to the unprotected sides and edges around the exterior edges of a floor or
working surface later to be enclosed by framed exterior walls, or whether i[t] appl[i]es to
all edges including interior edges created by stairway landings, stairwells and floor
openings.”
       Joel Foss testified the 15-foot trigger height “only applied to exterior opening --
the exterior fall hazard . . . . So it only applied to where there were exterior walls stood
up.”
       Based on Foss’s testimony, section 1716.2 would not be implicated here, where
the areas at issue were all on the interior of the structure. In any event, even if this
section were implicated, it would not supplant or supersede the other sections as we now
discuss.
       “It is not uncommon for more than one safety order to apply to a particular set of
facts. Applying principles of statutory construction, the [Appeals] Board will only find
that a more specific safety order is controlling where there is an actual conflict between
the two safety orders. [Citation.] Where it is possible to read the safety orders so that
they are in harmony with one another, the [Appeals] Board will do so.” (Cabrillo, supra,
2014 CA OSHA App.Bd. Lexis 116 at p. *8.)
       In Cabrillo, the employer asserted sections 1632, subdivision (b)(1) and 1716.2
were in conflict, the latter was more specific, and therefore it controlled. Because
Cabrillo addresses essentially the same issue as presented here, we quote it at length:
       “Section 1632 applies to ‘the static hazard of an existing opening’, which creates
both the danger of an employee accidentally walking into the hole, as well as debris
sliding onto the lower level, injuring those who may be below. [Citation.] . . . [U]nlike
section 1716.2[, subdivision ](f), ‘in addition to fall protection, section
1632[, subdivision ](b) provides protection against other objects, such as tools, falling
below the floor, roof, or skylight openings.’ By definition, the area where the employee
fell was a stairwell floor opening. [Citation.] As such, section 1632 applies to the

                                              28
opening. While there are overlapping purposes to the two safety orders, the hazards
identified by the two orders are not identical, and create no direct conflict. The Board
interprets safety orders in a manner consistent with the purpose of the Act, which is to
achieve a safe working environment for all Californians. [Citation.]
       “Section 1716.2[, subdivision ](f), which mandates use of guardrails or personal
fall protection when framing work is being done over 15 feet, does not create any
inherent conflict with the requirement to guard openings found in section 1632. There
was no violation of the section, as the employee who fell was not required to wear fall
protection at the height he was working at. Nor were the unprotected sides or edges of
the building required to be guarded, as the framing was not being done at a height over 15
feet. However, section 1632[, subdivision ](b)(1), which applies to stairwell openings,
includes no such height trigger, nor does it exclude framing work from its mandate; the
Division properly alleged a violation of this safety order, and the Board finds a violation.
       “While the Board recognizes that interpreting the safety orders is not always a
simple task, in this instance compliance with the terms of section 1632[, subdivision ]
(b)(1) by covering or guarding floor openings does not prevent an employer from also
complying with section 1716.2. It is both possible, and reasonable, to give concurrent
effect to both safety orders. [Citation.] Only where there is an actual conflict between
the orders will a more specific safety order control over the more general; that not being
shown in this instance, Employer’s defense therefore fails. [Citation.]
       “Additionally, the Board is not convinced that section 1716.2[, subdivision ](f) is
more specific than section 1632[, subdivision ](b)(1). Section 1632[, subdivision ](b)(1)
requires guarding of ‘[f]loor, roof and skylight openings . . . .’ Section 1504 defines
‘opening’ to include ‘stairway floor openings.’ In short, section 1632[, subdivision
](b)(1) specifically pertains to protecting stairway floor openings such as the one that
Martinez fell through. In contrast, section 1716.2[, subdivision ](f) requires guardrails
(or other appropriate protection) around ‘all unprotected sides or edges . . .’ over fifteen

                                             29
feet in height during framing activities. The latter regulation appears to be a more-
generalized guideline, applicable during the framing process, whether the working floor
contains openings or not, and does not specifically address the floor opening hazard.
Under the circumstances of this case, we conclude there is no conflict among the two
regulations, and so Employer must comply with both.” (Cabrillo, supra, 2014 CA
OSHA App.Bd. Lexis 116 at pp. *9-12.)
       For the reasons expressed in Cabrillo, we conclude section 1716.2 did not conflict
with either section 1632, subdivision (b)(1) or, based on the same reasoning, section
1626, subdivision (a)(2).
       Plaintiff again maintains that the Appeals Board’s determinations amount to
underground regulation and, under a separate point heading entitled, “Consequences of
Respondent’s and Lower Court’s Rulings,” asserts this creates a separation of powers
issue and further asserts, with examples, the Appeals Board’s “findings leave more
questions than answers.” (Bold and some capitalization omitted.) We disagree. While
we acknowledge that, going forward, as before, “interpreting the safety orders is not
always a simple task . . .” (Cabrillo, supra, 2014 CA OSHA App.Bd. Lexis 116 at
p. *10.) We conclude the Appeals Board here merely interpreted the subject regulations,
as opposed to effectively rewriting them, and its interpretations were reasonable.

       The judgment is affirmed. The Appeals Board and the Division shall recover their
costs on appeal. (Cal. Rules of Court, rule 8.278(a)(1), (2).)
