Calaveras Power Partners L.P., Matrix Service Inc., T. E. 
Ibberson Company, TIC--The Industrial Company, and Zachry Construction 
Corporation; Notice of Application for a Permanent Variance and Interim 
Order, Grant of an Interim Order, and Request for Comments

AGENCY: Occupational Safety and Health Administration (OSHA), 
Department of Labor.

ACTION: Notice of an application for a permanent variance and interim 
order; grant of an interim order; and request for comments.

-----------------------------------------------------------------------

SUMMARY: Calaveras Power Partners L.P., Matrix Service Inc., T. E. 
Ibberson Company, TIC--The Industrial Company, and Zachry Construction 
Corporation (``the applicants'') applied for a permanent variance from 
the provisions of the OSHA standards that regulate boatswain's chairs 
and hoist towers, specifically paragraph (o)(3) of 29 CFR 1926.452 and 
paragraphs (c)(1) through (c)(4), (c)(8), (c)(13), (c)(14)(i), and 
(c)(16) of 29 CFR 1926.552. In addition, the applicants requested an 
interim order based on the alternative conditions specified by the 
variance application. These alternative conditions consist of the same 
conditions specified in recent variances granted by OSHA from these 
hoist-tower and boatswain's-chair provisions, as well as several 
additional conditions that would provide employees with protection from 
shearing, fall, and struck-by hazards. Therefore, OSHA is granting the 
applicants' request for an interim order.

I. Notice of Application

    Calaveras Power Partners L.P., Matrix Service Inc., T. E. Ibberson 
Company, TIC--The Industrial Company, and Zachry Construction 
Corporation (hereafter, ``the applicants'') submitted applications for 
a permanent variance under Section 6(d) of the Occupational Safety and 
Health Act of 1970 (29 U.S.C. 655) and 29 CFR 1905.11 (``Variances and 
other relief under section 6(d)'') (see Exs. OSHA-2007-0046-0002 
through

[[Page 4238]]

-0006).\1\ The applicants seek a permanent variance from 29 CFR 
1926.452(o)(3), which provides the tackle requirements for boatswain's 
chairs. The applicants also request a variance from paragraphs (c)(1) 
through (c)(4), (c)(8), (c)(13), (c)(14)(i), and (c)(16) of 29 CFR 
1926.552 that regulate hoist towers. These latter paragraphs specify 
the following requirements:
---------------------------------------------------------------------------

    \1\ The principle addresses for the applicants are as follows: 
Calaveras Power Partners L.P., 527 Logwood, San Antonio, TX 78221; 
Matrix Service Inc., 3810 Bakerview Spur, Bellingham, WA 98226; T. 
E. Ibberson Company, 828 Fifth Street South, Hopkins, MN 55343-7750; 
TIC--The Industrial Company, 22001 North Park Drive, Suite 700, 
Kingwood, TX 77339; and Zachry Construction Corporation, 527 
Logwood, San Antonio, TX 78221.
---------------------------------------------------------------------------

     (c)(1)--Construction requirements for hoist towers outside 
a structure;
     (c)(2)--Construction requirements for hoist towers inside 
a structure;
     (c)(3)--Anchoring a hoist tower to a structure;
     (c)(4)--Hoistway doors or gates;
     (c)(8)--Electrically interlocking entrance doors or gates 
that prevent hoist movement when the doors or gates are open;
     (c)(13)--Emergency stop switch located in the car;
     (c)(14)(i)--Using a minimum of two wire ropes for drum 
hoisting; and
     (c)(16)--Material and component requirements for 
construction of personnel hoists.

The applicants contend that the permanent variance would provide their 
employees with a place of employment that is at least as safe and 
healthful as they would obtain under the existing provisions. The 
places of employment affected by this variance application are the 
present and future projects where the applicants construct chimneys, 
all of which are located in the State of Texas.
    The applicants certify that they provided employee representatives 
of current employees who would be affected by the permanent variance 
with a copy of their variance requests. The applicants also certify 
that they notified their employees of the variance requests by posting 
a summary of the application and specifying where the employees can 
examine a copy of the application at a prominent location or locations 
where they normally post notices to their employees (or, instead of a 
summary, posting the application itself); and by other appropriate 
means. In addition, the applicants have informed employees and their 
representatives of their right to petition the Assistant Secretary of 
Labor for Occupational Safety and Health for a hearing on this variance 
application.

II. Supplementary Information

A. Overview

    The applicants construct, remodel, repair, maintain, inspect, and 
demolish tall chimneys made of reinforced concrete, brick, and steel. 
This work requires the applicants to transport employees and 
construction material to and from elevated work platforms and scaffolds 
located, respectively, inside and outside tapered chimneys. While 
tapering contributes to the stability of a chimney, it requires 
frequent relocation of, and adjustments to, the work platforms and 
scaffolds so that they will fit the decreasing circumference of the 
chimney as construction progresses upwards.
    To transport employees to various heights inside and outside a 
chimney, the applicants propose to use a hoist system that would lift 
and lower personnel-transport devices (i.e., personnel cages, personnel 
platforms, or boatswain's chairs). The applicants also would attach 
material-transport devices such as hoppers, concrete buckets, or other 
containers to the hoist system to raise or lower construction material 
or equipment inside or outside a chimney. The applicants would use 
personnel cages, personnel platforms, or boatswain's chairs solely to 
transport employees with the tools and materials necessary to do their 
work, and not to transport only materials or tools in the absence of 
employees.

B. Previous Variances From 29 CFR 1926.452(o)(3) and 1926.552(c)

    Since 1973, a number of chimney-construction companies demonstrated 
to OSHA that several of the hoist-tower requirements of 29 CFR 
1926.552(c) present chimney-access problems that pose a serious danger 
to their employees. These companies received permanent variances from 
these personnel-hoist and boatswain's-chair requirements, and they used 
essentially the same alternate apparatus and procedures that the 
applicants are now proposing to use in this variance application. The 
Agency published the permanent variances for these companies at 38 FR 
8545 (April 3, 1973), 44 FR 51352 (August 31, 1979), 50 FR 20145 (May 
14, 1985), 50 FR 40627 (October 4, 1985), 52 FR 22552 (June 12, 1987), 
68 FR 52961 (September 8, 2003), 70 FR 72659 (December 6, 2005), and 71 
FR 10557 (March 1, 2006).\2\
---------------------------------------------------------------------------

    \2\ Zurn Industries, Inc. received two permanent variances from 
OSHA. The first variance, granted on May 14, 1985 (50 FR 20145), 
addressed the boatswain's-chair provision (then in paragraph (l)(5) 
of Sec.  1926.451), as well as the hoist-tower requirements of 
paragraphs (c)(1), (c)(2), (c)(3), and (c)(14)(i) of Sec.  1926.552. 
The second variance, granted on June 12, 1987 (52 FR 22552), 
included these same paragraphs, as well as paragraphs (c)(4), 
(c)(8), (c)(13), and (c)(16) of Sec.  1926.552.
---------------------------------------------------------------------------

    In 1980, the Agency evaluated the alternative conditions specified 
in the permanent variances that it had granted to chimney-construction 
companies as of that date. In doing so, OSHA observed hoisting 
operations conducted by these companies at various construction sites. 
These evaluations found that, while the alternative conditions 
generally were safe, compliance with the conditions among the companies 
was uneven (see Exs. OSHA-2007-0046-0007 and -0008). Additionally, the 
National Chimney Construction Safety and Health Advisory Committee, an 
industry-affiliated organization, conducted evaluations of the hoist 
systems that provided useful information regarding the safety and 
efficacy of the alternative conditions (see Ex. OSHA-2007-0046-0009).
    The permanent variance granted by OSHA to American Boiler and 
Chimney Co. and Oak Park Chimney Corp. (see 68 FR 52961, September 8, 
2003) updated the permanent variances granted by the Agency in the 
1970s and 1980s by clarifying the alternative conditions and citing the 
most recent consensus standards and other references. On the basis of 
this experience and knowledge, the Agency finds that the applicants' 
request for a permanent variance is consistent with the permanent 
variances that OSHA granted previously to other employers in the 
chimney-construction industry. Therefore, the Agency believes that the 
conditions specified in this variance application will provide the 
applicants' employees with at least the same level of safety they would 
receive from 29 CFR 1926.452(o)(3) and paragraphs (c)(1) through 
(c)(4), (c)(8), (c)(13), (c)(14)(i), and (c)(16) of 29 CFR 1926.552.

C. Requested Variance From 29 CFR 1926.452(o)(3)

    The applicants state that it is necessary, on occasion, to use a 
boatswain's chair to transport employees to and from a bracket scaffold 
on the outside of an existing tapered chimney during flue installation 
or repair work, or to and from an elevated scaffold located inside a 
chimney that has a tapering diameter. Paragraph (o)(3) of 29 CFR 
1926.452, which regulates the tackle used to rig a boatswain's chair, 
states that this tackle must ``consist of correct size ball bearings or 
bushed blocks containing safety hooks and properly `eye-spliced'

[[Page 4239]]

minimum five-eighth (5/8) inch (1.6 cm) diameter first-grade manila 
rope [or equivalent rope].''
    The primary purpose of this paragraph is to allow an employee to 
safely control the ascent, descent, and stopping locations of the 
boatswain's chair. However, the applicants note that the required 
tackle is difficult or impossible to operate on some chimneys that are 
over 200 feet tall because of space limitations. Therefore, as an 
alternative to complying with the tackle requirements specified by 29 
CFR 1926.452(o)(3), the applicants propose to use the hoisting system 
described in Section II.E (``Proposed Alternative to 29 CFR 
1926.452(o)(3) and 29 CFR 1926.552(c)'') of this notice, both inside 
and outside a chimney, to raise or lower employees in a personnel cage 
to work locations. The applicants would use a personnel cage for this 
purpose to the extent that adequate space is available; they would use 
a personnel platform whenever a personnel cage is infeasible because of 
limited space. However, when limited space also makes a personnel 
platform infeasible, the applicants then would use a boatswain's chair 
to lift employees to work locations. The applicants would limit use of 
the boatswain's chair to elevations above the highest work location 
that the personnel cage and personnel platform can reach; under these 
conditions, the applicants would attach the boatswain's chair directly 
to the hoisting cable only when the structural arrangement precludes 
the safe use of the block and tackle required by 29 CFR 1926.452(o)(3).

D. Requested Variance From 29 CFR 1926.552(c)

    Paragraph (c) of 29 CFR 1926.552 specifies the requirements for 
enclosed hoisting systems used to transport personnel from one 
elevation to another. This paragraph ensures that employers transport 
employees safely to and from elevated work platforms by mechanical 
means during the construction, alteration, repair, maintenance, or 
demolition of structures such as chimneys. However, this standard does 
not provide specific safety requirements for hoisting personnel to and 
from elevated work platforms and scaffolds in tapered chimneys; the 
tapered design requires frequent relocation of, and adjustment to, the 
work platforms and scaffolds. The space in a tapered chimney is not 
large enough or configured so that it can accommodate an enclosed hoist 
tower. Moreover, using an enclosed hoist tower for outside operations 
exposes employees to additional fall hazards because extra bridging and 
bracing must be installed to support a walkway between the hoist tower 
and the tapered chimney.
    Paragraph (c)(1) of 29 CFR 1926.552 requires employers to enclose 
hoist towers located outside a chimney on the side or sides used for 
entrance to, and exit from, the chimney; these enclosures must extend 
the full height of the hoist tower. The applicants assert that it is 
impractical and hazardous to locate a hoist tower outside tapered 
chimneys because it becomes increasingly difficult, as a chimney rises, 
to erect, guy, and brace a hoist tower; under these conditions, access 
from the hoist tower to the chimney or to the movable scaffolds used in 
constructing the chimney exposes employees to a serious fall hazard. 
Additionally, the applicants note that the requirement to extend the 
enclosures 10 feet above the outside scaffolds often exposes the 
employees involved in building these extensions to dangerous wind 
conditions.
    Paragraph (c)(2) of 29 CFR 1926.552 requires that employers enclose 
all four sides of a hoist tower even when the tower is located inside a 
chimney; the enclosure must extend the full height of the tower. The 
applicants contend that it is hazardous for employees to erect and 
brace a hoist tower inside a chimney, especially tapered chimneys, 
because these structures have limited space and cannot accommodate 
hoist towers; space limitations result from chimney design (e.g., 
tapering), as well as reinforced steel projecting into the chimney from 
formwork that is near the work location.
    As an alternative to complying with the hoist-tower requirements of 
29 CFR 1926.552(c)(1) and (c)(2), the applicants propose to use the 
hoist system described below in Section II.E (``Proposed Alternative to 
29 CFR 1926.452(o)(3) and 29 CFR 1926.552(c)'') of this notice to 
transport employees to and from work locations inside and outside 
chimneys. Use of the proposed hoist system would eliminate the need for 
the applicants to comply with other provisions of 29 CFR 1926.552(c) 
that specify requirements for hoist towers. Therefore, the applicants 
also are requesting a permanent variance from the following related 
provisions:
     (c)(3)--Anchoring the hoist tower to a structure;
     (c)(4)--Hoistway doors or gates;
     (c)(8)--Electrically interlocking entrance doors or gates 
that prevent hoist movement when the doors or gates are open;
     (c)(13)--Emergency stop switch located in the car;
     (c)(14)(i)--Using a minimum of two wire ropes for drum-
type hoisting; and
     (c)(16)--Material and component requirements for 
construction of personnel hoists.
    The applicants assert that the proposed hoisting system would 
protect its employees at least as effectively as the hoist-tower 
requirements of 29 CFR 1926.552(c).

E. Proposed Alternative to 29 CFR 1926.452(o)(3) and 29 CFR 1926.552(c)

    To power the hoist system, the applicants would use a hoist engine, 
located and controlled outside the chimney. The system also would 
consist of a wire rope that: Spools off the hoist drum into the 
interior of the chimney; passes to a footblock that redirects the rope 
from the horizontal to the vertical planes; goes from the footblock 
through the overhead sheaves above the elevated platform; and finally 
drops to the bottom landing of the chimney where it connects to a 
personnel- or material-transport device. The cathead, which is a 
superstructure at the top of the hoist system, supports the overhead 
sheaves. The overhead sheaves (and the vertical span of the hoist 
system) move upward with the hoist system as chimney construction 
progresses. Two guide cables, suspended from the cathead, eliminate 
swaying and rotation of the load. If the hoist rope breaks, safety 
clamps activate and grip the guide cables to prevent the load from 
falling. The applicants would use a headache ball, located on the hoist 
rope directly above the load, to counterbalance the rope's weight 
between the cathead sheaves and the footblock.
    The applicants would implement additional conditions to improve 
employee safety, including:
    (1) Attaching the wire rope to the personnel cage using a keyed-
screwpin shackle or positive-locking link;
    (2) Adding limit switches to the hoist system to prevent overtravel 
by the personnel- or material-transport devices;
    (3) Providing the safety factors and other precautions required for 
personnel hoists specified by the pertinent provisions of 29 CFR 
1926.552(c), including canopies and shields to protect employees 
located in a personnel cage from material that may fall during hoisting 
and other overhead activities;
    (4) Providing falling-object protection for scaffold platforms as 
specified by 29 CFR 1926.451(h)(1);
    (5) Conducting tests and inspections of the hoist system as 
required by 29 CFR 1926.20(b)(2) and 1926.552(c)(15);

[[Page 4240]]

    (6) Establishing an accident-prevention program that conforms to 29 
CFR 1926.20(b)(3);
    (7) Equipping employees who use a personnel cage, personnel 
platform, or boatswain's chair with, and ensuring that they use, 
personal fall-arrest systems meeting the requirements of 29 CFR 
1926.502(d);
    (8) Ensuring that employees using a personnel cage secure their 
personal fall-arrest system to an attachment point located inside the 
cage, and that employees using personnel platforms or boatswain's 
chairs secure their personal fall-arrest systems to a vertical 
lifeline;
    (9) When using vertical lifelines, securing the lifelines to the 
top of the chimney and weighting the lifelines properly or suitably 
affixing the lifelines to the bottom of the chimney, and ensuring that 
employees remain attached to their lifeline during the entire period of 
vertical transit;
    (10) Providing instruction to each employee who uses a personnel 
platform or boatswain's chair regarding the shearing hazards posed by 
the hoist system (e.g., work platforms, scaffolds), and the need to 
keep their limbs or other body parts clear of these hazards during 
hoisting operations;
    (11) Providing the instruction on shearing hazards before an 
employee uses one of these personnel-transport devices at the worksite; 
and periodically, and as necessary, thereafter, including whenever the 
employee demonstrates a lack of knowledge about the hazard and how to 
avoid it, a modification occurs to an existing shearing hazard, or a 
new shearing hazard develops at the worksite;
    (12) Attaching a readily visible warning to each personnel platform 
and boatswain's chair notifying employees in a language they understand 
of potential shearing hazards during hoisting operations. For warnings 
located on personnel platforms, using the following (or equivalent) 
wording: ``Warning--To avoid serious injury, keep your hands, arms, 
feet, legs, and other parts of your body inside this platform while it 
is in motion.'' For boatswain's chairs, the warning would use the 
following (or equivalent) wording: ``Warning--To avoid serious injury, 
do not extend your hands, arms, feet, legs, or other parts of your body 
from the side or to the front of this chair while it is in motion; and
    (13) Establishing a clearly designated safety zone around the hoist 
system's bottom landing and prohibiting any employee from entering the 
safety zone except to access a personnel cage, personnel platform, 
boatswain's chair, or material-transport device, and then only when the 
personnel- and material-transport device is at the bottom landing and 
not in operation.
    OSHA revised the requirements for using personal fall-protection 
systems specified in previous variances addressing these hoist systems 
(see Conditions 7 and 8, above). This revision adds a requirement that 
the applicants provide employees using personnel cages with personal 
fall-protection systems, and ensure that the employees use these 
systems, in accordance with 29 CFR 1926.502(d). OSHA believes this 
revision will protect employees from falling out of a cage in the event 
the door of the cage opens inadvertently during lifting operations.
    The last four of these conditions (Conditions 10-13) also are new, 
having never been part of previous variance applications covering these 
hoist systems. OSHA believes that these additional conditions are 
necessary to protect employees from shearing, fall, and struck-by 
hazards associated with using hoist systems in chimney construction. 
Accordingly, conditions 10-12 address shearing hazards that employees 
may encounter while a personnel platform or boatswain's chair is 
transporting them to or from an elevated jobsite. During transport, the 
personnel-transport device will pass near structures, including work 
platforms and scaffolds, that could crush or inflict other serious 
injury on a hand, arm, foot, leg, or other body part that extends 
beyond the confines of the device. To prevent these injuries, OSHA 
believes that employees who use these devices must be able to recognize 
shearing hazards at the worksite, and how to avoid them. Additionally, 
attaching a readily visible warning of the hazards to personnel 
platforms and boatswain's chairs would supplement and reinforce the 
hazard training by reminding employees of the hazard and how to avoid 
it.
    The last condition (Condition 13) requires the applicants to 
establish a safety zone around the bottom landing where employees 
access personnel- and material-transport devices. The applicants must 
ensure that employees enter the safety zone only to access a transport 
device that is in the area circumscribed by the safety zone, and only 
when the hoist system is not in operation. This condition will prevent 
a transport device that is descending from an elevated jobsite from 
striking an employee who is in or near the bottom-landing area and is 
not aware of the descending device. During descent, it also is 
difficult for employees in or on these devices to detect an employee 
beneath them. Therefore, it is necessary for the applicants to 
establish a safety zone and ensure that employees only enter the safety 
zone when a transport device is at the bottom landing and not in 
operation (i.e., the drive components of the hoist system are 
disengaged and the braking mechanism is properly applied).
    This variance application also specifies a condition that requires 
the applicants to notify (1) the nearest OSHA Area Office at least 15 
days before commencing chimney-construction operations covered by the 
variance, and (2) OSHA national headquarters as soon as an applicant 
knows that it will cease doing business or transfers the activities 
covered by the variance to another company. These administrative 
requirements will enable OSHA to more easily enforce, and determine the 
status of, the variance than is presently the case. Currently, OSHA has 
little or no information about chimney-construction activities 
conducted under a variance, making it difficult for it to assess 
compliance with the conditions specified under the variance. 
Additionally, OSHA finds that construction companies cease operations 
or transfer chimney-construction assets to successor companies without 
informing OSHA that the variance is no longer needed or requesting that 
the Agency reassign the variance to the successor company. OSHA 
believes that these notification requirements would improve 
administrative oversight of the variance program, thereby enhancing 
employee safety and reducing its administrative burden.

III. Grant of Interim Order

    In addition to requesting a permanent variance, the applicants also 
requested an interim order that would remain in effect until the Agency 
makes a decision on their application for a permanent variance. During 
this period, the applicants must comply fully with the conditions of 
the interim order as an alternative to complying with the tackle 
requirements provided for boatswain's chairs by 29 CFR 1926.452(o)(3) 
and the requirements for hoist towers specified by paragraphs (c)(1) 
through (c)(4), (c)(8), (c)(13), (c)(14)(i), and (c)(16) of 29 CFR 
1926.552.
    Based on its previous experience with permanent variances from 
these provisions granted to other companies, OSHA believes that an 
interim order is justified in this case. As noted above in Section II.B 
(``Previous Variances from 29 CFR 1926.452(o)(3) and 1926.552(c)''), 
the Agency has granted a number of permanent variances from

[[Page 4241]]

these provisions since 1973. Over this period, the affected companies 
have effectively used the alternative conditions specified in the 
variances. The conditions of the interim order requested by the 
applicants substantially duplicate the conditions approved recently in 
the permanent variance granted to American Boiler and Chimney Co. and 
Oak Park Chimney Corp. (see 68 FR 52961), while adding conditions that 
would provide employees with protection from shearing, fall, and 
struck-by hazards. In granting a permanent variance to American Boiler 
and Chimney Co. and Oak Park Chimney Corp., the Agency stated, ``[W]hen 
the employers comply with the conditions of the following order, their 
employees will be exposed to working conditions that are at least as 
safe and healthful as they would be if the employers complied with 
paragraph (o)(3) of 29 CFR 1926.452, and paragraphs (c)(1) through 
(c)(4), (c)(8), (c)(13), (c)(14)(i), and (c)(16) of 29 CFR 1926.552.'' 
(See 68 FR 52967.)
    Based on its determination that the alternative conditions proposed 
by American Boiler and Chimney Co. and Oak Park Chimney Corp will 
protect employees at least as effectively as the requirements of 
paragraph (o)(3) of 29 CFR 1926.452 and paragraphs (c)(1) through 
(c)(4), (c)(8), (c)(13), (c)(14)(i), and (c)(16) of 29 CFR 1926.552, as 
well as the additional conditions specified in this variance 
application that will protect employees from shearing, fall, and 
struck-by hazards, OSHA has decided to grant an interim order to the 
applicants pursuant to the provisions of 29 CFR 1905.11(c). 
Accordingly, in lieu of complying with paragraph (o)(3) of 29 CFR 
1926.452 and paragraphs (c)(1) through (c)(4), (c)(8), (c)(13), 
(c)(14)(i), and (c)(16) of 29 CFR 1926.552, the applicants will: (1) 
Provide notice of this grant of an interim order to the employees 
affected by the conditions of the interim order using the same means it 
used to inform these employees of their applications for a permanent 
variance; and (2) comply with the conditions listed below in section IV 
(``Specific Conditions of the Interim Order and the Application for a 
Permanent Variance'') of this application for the period between the 
date of this Federal Register notice and the date the Agency publishes 
its final decision on the application in the Federal Register; the 
interim order will remain in effect during this period unless OSHA 
modifies or revokes it in accordance with the requirements of 29 CFR 
1905.13.
