Carbon Dioxide Fire Suppression Systems on Commercial Vessels

AGENCY: Coast Guard, DHS.

ACTION: Notice of proposed rulemaking.

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

SUMMARY: The Coast Guard proposes to amend the current regulations for 
fire suppression systems on several classes of commercial vessels. The 
amendments would clarify that approved alternatives to carbon dioxide 
systems may be used to protect some spaces on these vessels and would 
set general requirements for alternative systems.
    Additionally, new and existing carbon dioxide systems, when used in 
spaces that can be accessed by persons onboard the specified commercial 
vessels, would need to be equipped with lockout valves and olfactory 
additives to protect persons in the event of a carbon dioxide 
discharge. By requiring these features on carbon dioxide systems and by 
making a wider range of fire suppression systems available, the 
proposed regulations advance the Coast Guard's mission of promoting 
maritime safety and mobility.

III. Background

    Until recently, carbon dioxide (CO2) systems were the 
only systems suitable for suppressing or extinguishing fires in certain 
vessel spaces, such as those used for cargo and various types of 
machinery. Our current regulations require the use of CO2 
systems in such spaces on towing vessels, tank vessels, cargo and 
miscellaneous vessels, mobile offshore drilling units (MODUs), offshore 
supply vessels, public nautical school ships, and large passenger 
vessels (``Subchapter H'' vessels). We also allow carbon dioxide 
systems on small passenger vessels carrying more than 150 passengers or 
with overnight accommodations for more than 49 passengers (``Subchapter 
K'' vessels) and other small passenger vessels (``Subchapter T'' 
vessels).
    Carbon dioxide systems work by flooding a protected space with 
CO2, thereby depriving a fire of the oxygen it needs to 
burn. Unfortunately, when a carbon dioxide discharge occurs, oxygen 
deprivation poses a risk to persons who may be in this protected space. 
Crew members have died when odorless CO2 gas was discharged 
in their spaces accidentally or without adequate warning to evacuate.
    In recent years, alternative systems have been developed that are 
comparable to carbon dioxide systems in their ability to suppress 
fires, but that do not pose the same risks to persons onboard. Our 
regulations currently allow for the use of Coast Guard-approved 
alternative systems. At present, most approved systems use halocarbon 
clean agents HFC[dash]227ea (heptafluoropropane), 
FK[dash]5[dash]1[dash]12 (dodecafluoro-2-methylpentan-3-one), or 
IG[dash]541 (nitrogen 52%, argon 40%, and carbon dioxide 8%). We have 
also approved water mist systems for some applications. These systems 
have been tested by independent testing laboratories and have 
laboratory listings. Systems using other agents may be developed and 
approved in the future.
    Along with the manufacturers of alternative systems, shipyards, and 
independent testing laboratories, we believe it would promote safety 
and be advantageous to industry to issue new regulations for 
installing, maintaining, and using approved carbon dioxide-alternative 
fire suppression systems.

IV. Discussion of Proposed Rule

    We are proposing two overall changes to our regulations.
    1. Lockout valves and olfactory additives.
    We propose requiring lockout valves and olfactory additives in any 
CO2 system used in a space that may be occupied by persons 
onboard, even if only occasionally.
    Lockout valves, which are already required for shore-based 
facilities by National Fire Protection Association standards (NFPA 12, 
2008 edition), are intended to be used during system maintenance to 
prevent inadvertent flooding of a protected space. We would require 
lockout valves on vessels that use CO2 systems in spaces 
containing more than 6,000 cubic feet and in smaller spaces that do not 
have horizontal escapes, which provide a quick way to evacuate. 
Odorizer units would be required for CO2 systems of any size 
to provide a scent to normally odorless CO2 during 
discharge. A distinctive-smelling substance, like wintergreen, is added 
to the CO2 so that in the event of a CO2 
discharge in a vessel's space, any persons in that space can quickly 
smell the discharge and evacuate.
    Additionally, the odor would warn persons in adjacent spaces that 
the CO2 may have migrated. The new lockout valve and 
olfactory additive requirements would apply immediately to new systems. 
They would be phased-in for existing systems, allowing the necessary 
simple retrofits to be made during drydocking or routine maintenance, 
thereby reducing the financial impact on vessel owners. Retrofitting 
would involve dismantling and reassembling a small section of system 
piping to include a lockout valve.
    2. Alternative systems.
    The second overall change we propose is to amend our existing 
regulations to make it clear that alternative systems using clean agent 
and inert gases may be used. Furthermore, we are proposing 
clarifications to the general requirements for maintaining, installing, 
and using an alternative system. System layout and control requirements 
would be based on the current regulations for engineered CO2 
systems on inspected vessels. Independent laboratories would oversee 
prototype testing and follow-up quality control supervision.
    The following table lists the parts within 46 CFR that are affected 
by our proposal and the specific sections we propose to amend. The 
foregoing discussion provides a general explanation for each of these 
changes. When additional information is required, it appears in the 
table in parentheses. The table omits any discussion of numerous minor 
and nonsubstantive style, format, or wording changes that we are 
proposing solely to improve the clarity of our regulations.

ADDRESSES. Copies of the material are available from the sources listed 
in 46 CFR 34.01-15, 46 CFR 147.7, and 46 CFR 162.161-2.
    Before publishing a binding rule, we will submit this material to 
the Director of the Federal Register for approval of the incorporation 
by reference.

VI. Regulatory Analysis

    We developed this proposed rule after considering numerous statutes 
and executive orders related to rulemaking. Below we summarize our 
analyses based on 13 of these statutes or executive orders.

A. Regulatory Planning and Review

    This proposed rule is not a significant regulatory action under 
section 3(f) of Executive Order 12866, Regulatory Planning and Review, 
and does not require an assessment of potential costs and benefits 
under section 6(a)(3) of that Order. The Office of Management and 
Budget (OMB) has not reviewed it under that Order.
    A draft Regulatory Analysis is available in the docket where 
indicated under the ``Public Participation and Request for Comments'' 
section of this preamble. A summary of the preliminary Regulatory 
Analysis follows.
    We propose to amend the current regulations for carbon dioxide fire 
suppression systems on commercial vessels. The amendments would require 
certain safety requirements for current and future users of 
CO2 systems. The proposed rule would require lockout valves 
for certain protected spaces as well as for an olfactory additive as a 
warning measure for all CO2 systems. The proposed rule would 
also clarify what approved alternatives to CO2 systems may 
be used to protect some spaces on these vessels and would set general 
requirements for alternative systems. We do not expect industry would 
incur additional costs as a result of the provisions for alternative 
systems. See below for additional discussion of alternative systems.
    Carbon dioxide fire suppression systems pose a risk of asphyxiation 
to personnel. Lockout valves and olfactory additives help protect 
persons in the event of an inadvertent release during maintenance. 
Olfactory additives offer additional protection from leaks from a 
protected space to adjacent spaces and help alert personnel when 
CO2 has been released. By requiring these features on carbon 
dioxide systems and making a wider range of fire suppression systems 
available, the proposed amendments would advance the Coast Guard's 
missions of promoting maritime safety and mobility.
    U.S. flag vessel owners are expected to incur costs associated with 
this proposed rule. Vessel owners with existing CO2 fire 
suppression systems would be required to add the lockout valves and 
olfactory units within five years of the publication of the final rule. 
This would allow enough time for vessel owners to add these features 
during scheduled vessel maintenance periods and would reduce the cost 
of compliance for vessel owners. For purposes of this regulatory 
assessment, we assume an equal proportion of systems will be 
retrofitted each year for five years. New vessel owners will incur the 
costs as systems are incorporated into new ships at construction.
Affected Population
    Vessels with CO2 fire suppression systems that are not 
in compliance with the proposed regulation would be required to install 
lockout valves at entrances to all spaces greater than 6,000 cubic feet 
in volume where personnel may enter, as well as, in spaces with 6,000 
cubic feet in volume or less that do not have a horizontal escape for 
quick escape. Vessels equipped with existing CO2 fire 
suppression systems would incur a cost for retrofitting valves to the 
systems. Newly constructed vessels installing new fire CO2 
suppression systems in similar spaces would also incur a cost for 
installation of lockout valves, although at a lower cost than 
retrofitting systems on existing vessels because installations during 
vessel construction are typically less costly.
    Based on Coast Guard Marine Investigation Security and Law 
Enforcement (MISLE) data, we estimate

[[Page 8435]]

there are potentially 1,702 existing vessels with a total of 3,204 
CO2 fire suppression systems that would require lockout 
valves. The 3,204 existing systems consist of 1,054 larger systems that 
would require more expensive lockout valves and 2,150 smaller systems 
that would require less expensive lockout valves. Using MILSE data, we 
estimate there are potentially 22 small systems and 12 large systems 
installed each year on new vessels, which would be required to have 
lockout valves.
    The population of affected vessels that would need to install 
olfactory additives (odorizers) includes all existing and new vessels 
with CO2 systems. All existing vessels with CO2 
systems would require a retrofit for each protected space. Based on 
MISLE data, we estimate there are potentially 7,815 systems on 3,567 
vessels that would be required to install odorizers.\1\ Each new vessel 
with CO2 systems would also require an odorizer for 
compartments of all sizes. Of the new vessels constructed annually, we 
estimate the 46 new systems/year installed would require odorizers.
---------------------------------------------------------------------------

    \1\ The difference in the vessel populations and system counts 
(lockout valve vs. odorizers) is reflective of the large number of 
extremely small sized systems that need odorizers, but do not need 
lockout valves (the balance of 7,815-3,204 or 4,611).
---------------------------------------------------------------------------

Costs
    Based on industry data, we estimate that average 2008 industry 
prices for installed retrofit large and small lockout valves are $3,513 
and $1,475, respectively. Systems that handle more than 2,450 pounds of 
CO2 require a valve larger than 2 inches. Of the 3,204 
existing systems affected by this proposed rule, 1,054 would require 
the larger, more expensive lockout valves, while 2,150 systems require 
the smaller valves for a total undiscounted cost of about $6,873,425. 
The annual undiscounted cost for owners of vessels with existing 
systems to meet the lockout valve requirement of this proposed rule 
would be approximately $1,374,685 for each year of the five-year phase-
in period.
    Vessel owners wishing to install a new CO2 fire 
suppression system would be required to have the lockout valves 
included in the installation. We estimate that the annual undiscounted 
industry cost for adding lockout valves to new CO2 fire 
suppression systems to be $65,932 per year (based on installed costs on 
new systems of $1,258 for small valves and $3,188 for large valves). 
Industry would incur this cost for each year over the ten-year period 
of analysis.
    As for odorizers, we estimate that the retrofit installed costs, 
including three warning signs, are $551/unit based on industry 
information. This is about $35 more than the estimated cost for new 
odorizers installed. With a five-year phase-in for all 7,815 systems, 
1,563 systems will be retrofitted on average each year. We estimate the 
total annual undiscounted cost of the retrofit will be $861,213. For 
new systems using the lockout valve, we estimate the total annual 
undiscounted cost to be about $17,558 for all 34 protected areas. For 
the remaining systems not required to have a lockout valve, the cost 
for installing odorizers in 12 areas will be about $6,197. The total 
cost per vessel would be dependent on the number of areas protected by 
CO2.
    We estimated the total cost of this rulemaking over a ten-year 
period to be $12.1 million (see Table 2). For the first five years, we 
estimated the undiscounted costs to be $2,325,584/year for both 
retrofits and new installations.

Note: Totals may not add due to rounding.

    For the remaining years, the undiscounted costs are $89,686/year 
due to the new installations only. We discounted the annual costs at 3 
percent and 7 percent and also annualized the total costs at the same 
rates. The total 10-year cost of the proposed rule is $9.8 million at a 
7 percent discount rate and $11 million at 3 percent.
    This proposed regulation would clarify Coast Guard acceptance of 
alternatives to using CO2 systems. We do not believe that 
these provisions would have a cost impact because the Coast Guard has 
been approving alternative systems on an ad hoc basis. We believe these 
approved installed alternative systems would be compliant with the 
requirements for alternative systems proposed in this rulemaking.
    With regard to alternative fire suppression systems, the use of 
halocarbon (only one of a number of alternatives) fire suppression 
systems has been increasing in recent years (2006-2008). Our records 
indicate that industry installed an average of 21 halocarbon fire 
suppression systems compared to an average of 34 CO2 fire 
suppression systems with capacity over 6,000 cubic feet during this 
period.
Benefits
    The primary benefit associated with this proposed rule is the 
reduction in risk of injuries and fatalities related to CO2 
exposure. CO2 exposure has long been recognized as a 
potential hazard to human health. The National Institute of 
Occupational Safety and Health (NIOSH), in its publication NIOSH 76-
194, ``Criteria for a Recommended

[[Page 8436]]

Standard--Occupational Exposure to Carbon Dioxide,'' available at 
http://www.cdc.gov/niosh/76-194.html, has set criteria for a standard 
for limits of exposure to CO2 in workplace settings.
    Other Federal and industry agencies and associations have also 
recently concluded that CO2 fire suppression systems could 
pose a risk. For example, the National Fire Prevention Association 
(NFPA) guidance in its 2005 Edition for CO2 fire suppression 
systems located on land states that ``total flooding CO2 
suppression systems shall not be used in normally occupied 
enclosures''. In addition, the EPA, in its 2000 report, ``Carbon 
Dioxide as a Fire Suppressant: Examining the Risk,'' has suggested that 
clarifying maritime regulation would be beneficial to reducing 
accidental exposure.
    The Regulatory Analysis available in the docket has additional 
detail on the assessment of the benefits and costs of this rulemaking. 
The assessment also contains details and analysis of the alternatives 
considered for this rulemaking.

B. Small Entities

    Under the Regulatory Flexibility Act (5 U.S.C. 601-612), we have 
considered whether this proposed rule would have a significant economic 
impact on a substantial number of small entities. The term ``small 
entities'' comprises small businesses, not-for-profit organizations 
that are independently owned and operated as well as not being dominant 
in their fields, and governmental jurisdictions with populations of 
less than 50,000.
    A combined Regulatory Assessment and Initial Regulatory Flexibility 
Analysis discussing the impact of this proposed rule on small entities 
is available in the docket where indicated under the ``Public 
Participation and Request for Comments'' section of this preamble.
    Our data shows that there are 489 known entities that owned vessels 
with CO2 fire suppression systems onboard in 2008. Of the 
489, 26 are government entities with populations of more than 50,000 
that we excluded from the small business analysis. Of the remaining 463 
entities, we were able to find revenue and employment information for 
100 entities. Of the 100, we confirmed that 37 were small as defined by 
Small Business Administration (SBA) size standards.
    We assumed the remaining 363 entities to be small because we were 
unable to find revenue or employment information. Given that assumption 
of size, we concluded that small entities likely comprise 400 (363 + 
37) or 81.8% of the total affected population.
    Of the small entities with revenue and employee size data, we 
determined that 83.8% would have an annual revenue impact of less than 
1 percent. Further, we estimated that the impact on 97.3% of these 
small entities would be less than 3% of annual revenue.
    Therefore, the Coast Guard certifies under 5 U.S.C. Sec.  605(b) 
that this rulemaking would not have a significant economic impact on a 
substantial number of small entities. We are interested in the 
potential impacts from this proposed rule on small businesses and we 
request public comment on these potential impacts. If you think that 
your business, organization, or governmental jurisdiction qualifies as 
a small entity and that this rulemaking would have a significant 
economic impact on it, please submit a comment to the Docket Management 
Facility at the address under the ``Public Participation and Request 
for Comments'' section of this preamble. In your comment, explain why, 
how, and to what degree you think this rule would have an economic 
impact on you.

C. Assistance for Small Entities

    Under section 213(a) of the Small Business Regulatory Enforcement 
Fairness Act of 1996 (Pub. L. 104-121), we want to assist small 
entities in understanding the proposed rule so that they can better 
evaluate its effects on them and participate in the rulemaking. If the 
rule affects your small business, organization, or governmental 
jurisdiction and you have questions concerning its provisions or 
options for compliance, please call Lieutenant Commander Suzanne 
Hemann, CG-5214, U.S. Coast Guard, telephone 202-372-1356 or send her 
an e-mail at suzanne.e.hemann@uscg.mil. The Coast Guard will not 
retaliate against small entities that question or complain about this 
rule or any policy or action of the Coast Guard.
    Small businesses may send comments on the actions of Federal 
employees who enforce, or otherwise determine compliance with, Federal 
regulations to the Small Business and Agriculture Regulatory 
Enforcement Ombudsman and the Regional Small Business Regulatory 
Fairness Boards. The Ombudsman evaluates these actions annually and 
rates each agency's responsiveness to small business. If you wish to 
comment on actions by employees of the Coast Guard, call 1-888-REG-FAIR 
(1-888-734-3247).

D. Collection of Information

    This proposed rule would require no new collection of information 
(COI) under the Paperwork Reduction Act (44 U.S.C. 3501-3520). The U.S. 
Coast Guard has been approving alternatives to CO2 systems 
for a number of years and accounting for it in COI document ``OMB 
Control Number 1625-0035''. This rulemaking would not require any new 
recordkeeping or reporting requirements. Satisfactory lockout valve and 
olfactory installation will be confirmed by normal future Coast Guard 
inspections.

E. Federalism

    A rule has implications for federalism under Executive Order 13132, 
Federalism, if it has a substantial direct effect on State or local 
governments and would either preempt State law or impose a substantial 
direct cost of compliance on them. We have analyzed this proposed rule 
under that Order and have determined that it does not have implications 
for federalism.

F. Unfunded Mandates Reform Act

    The Unfunded Mandates Reform Act of 1995 (2 U.S.C. 1531-1538) 
requires Federal agencies to assess the effects of their discretionary 
regulatory actions. In particular, the Act addresses actions that may 
result in the expenditure by a State, local, or tribal government, in 
the aggregate, or by the private sector of $100,000,000 or more in any 
one year. Though this proposed rule would not result in such an 
expenditure, we do discuss the effects of this rule elsewhere in this 
preamble.

G. Taking of Private Property

    This proposed rule would not affect a taking of private property or 
otherwise have taking implications under Executive Order 12630, 
Governmental Actions and Interference with Constitutionally Protected 
Property Rights.

H. Civil Justice Reform

    This proposed rule meets applicable standards in sections 3(a) and 
3(b)(2) of Executive Order 12988, Civil Justice Reform, to minimize 
litigation, eliminate ambiguity, and reduce burden.

I. Protection of Children

    We have analyzed this proposed rule under Executive Order 13045, 
Protection of Children from Environmental Health Risks and Safety 
Risks. This rule is not an economically significant rule and would not 
create an environmental risk to health or risk to

[[Page 8437]]

safety that might disproportionately affect children.

J. Indian Tribal Governments

    This proposed rule does not have tribal implications under 
Executive Order 13175, Consultation and Coordination with Indian Tribal 
Governments, because it would not have a substantial direct effect on 
one or more Indian tribes, on the relationship between the Federal 
Government and Indian tribes, or on the distribution of power and 
responsibilities between the Federal Government and Indian tribes.

K. Energy Effects

    We have analyzed this proposed rule under Executive Order 13211, 
Actions Concerning Regulations That Significantly Affect Energy Supply, 
Distribution, or Use. We have determined that it is not a ``significant 
energy action'' under that order because it is not a ``significant 
regulatory action'' under Executive Order 12866 and is not likely to 
have a significant adverse effect on the supply, distribution, or use 
of energy. The Administrator of the Office of Information and 
Regulatory Affairs has not designated it as a significant energy 
action. Therefore, it does not require a Statement of Energy Effects 
under Executive Order 13211.

L. Technical Standards

    The National Technology Transfer and Advancement Act (NTTAA) (15 
U.S.C. 272 note) directs agencies to use voluntary consensus standards 
in their regulatory activities unless the agency provides Congress, 
through the Office of Management and Budget, with an explanation of why 
using these standards would be inconsistent with applicable law or 
otherwise impractical. Voluntary consensus standards are technical 
standards (e.g. specifications of materials, performance, design, or 
operation; test methods; sampling procedures; and related management 
systems practices) that are developed or adopted by voluntary consensus 
standard bodies.
    This proposed rule uses the following consensus standards: 
Underwriters Laboratories (UL) standards UL 2127 entitled ``Standard 
for Inert Gas Clean Agent Extinguishing System Units,'' UL 2166 
entitled ``Standard for Halocarbon Clean Agent Extinguishing System 
Units,'' and National Fire Protection Association (NFPA) 2001 entitled 
``Standard on Clean Agent Fire Extinguishing Systems.'' The proposed 
sections that reference these standards and the locations where these 
standards are available are listed in the proposed regulatory text for 
46 CFR 34.01-15, 147.7, and 162.161-2.
    This proposed rule also uses technical standards other than 
voluntary consensus standards. The test described in the regulatory 
text proposed for 46 CFR 162.161-6 is in accordance with requirements 
of the International Maritime Organization, IMO MSC/Circ.848 entitled 
``Revised Guidelines for the Approval of Equivalent Fixed Gas Fire-
Extinguishing Systems, as referred to in chapter II-2 of SOLAS 74, for 
machinery spaces and cargo pump-rooms'' and IMO MSC.1/Circ. 1267 
entitled ``Amendments to the Revised Guidelines for the Approval of 
Equivalent Fixed Gas Fire-Extinguishing Systems, as referred to in 
chapter II-2 of SOLAS 74, for machinery spaces and cargo pump-rooms 
(MSC/Circ. 848)''. The remaining requirements and tests were developed 
by the Coast Guard and used to evaluate currently-approved carbon 
dioxide-alternative fire suppression systems. These requirements are 
described throughout the proposed regulations. They are used because we 
did not find voluntary consensus standards that are applicable to this 
rule. If you disagree with our analysis of the voluntary consensus 
standards listed above or are aware of voluntary consensus standards 
that might apply, but are not listed, please send a comment to the 
docket using one of the methods under ADDRESSES. In your comment, 
please explain why you disagree with our analysis and/or identify 
voluntary consensus standards we have not listed that might apply.

M. Environment

    We have analyzed this proposed rule under Department of Homeland 
Security Management Directive 023-01 and Commandant Instruction 
M16475.lD, which guide the Coast Guard in complying with the National 
Environmental Policy Act of 1969 (NEPA) (42 U.S.C. 4321-4370f), and 
have made a preliminary determination that this action is one of a 
category of actions which do not individually or cumulatively have a 
significant effect on the human environment. A preliminary 
environmental analysis checklist supporting this determination is 
available in the docket where indicated under the ``Public 
Participation and Request for Comments'' section of this preamble. This 
rule involves amending the current regulations for carbon dioxide fire 
suppression systems on several classes of commercial vessels. Exclusion 
under paragraphs (34)(d) of Figure 2.1 of the Instruction and section 
6(a) of the Federal Register, Vol. 67, No. 141, Tuesday July 23, 2002, 
page 48243 apply because this rule pertains to regulations concerning 
the equipping of vessels, as well as equipment approval. We seek any 
comments or information that may lead to the discovery of a significant 
environmental impact from this proposed rule.

Sec.  76.05-1  Fire detecting systems.

    (a) On the following vessels, approved fire detecting systems must 
be installed in the locations indicated by Table 76.05-1(a):
    (1) Any vessel on an international voyage;
    (2) Any vessel of more than 150 feet in length having sleeping 
accommodations for passengers; and
    (3) Any vessel of 150 feet or less in length that has sleeping 
accommodations for 50 or more passengers. Vessels that are not on an 
international voyage are not required to have a detecting system in the 
cargo spaces.

Notes to Table 76.05-1(a)
\1\ Vessels of 100 gross tons and over contracted for, on, or before May
  27, 1936, and having combustible joiner work must be fitted with an
  automatic sprinkling system, except in relatively incombustible
  spaces.
\2\ On vessels contracted for prior to November 19, 1952, electric or
  pneumatic detecting may be substituted.
\3\ On vessels contracted for prior to January 1, 1962, a steam
  smothering system may be accepted. However, although existing steam
  smothering systems may be repaired, replaced, or extended, no new
  system contracted for on or after January 1, 1962, will be permitted.
\4\ Protection of auxiliary boilers, fuel oil units, valves, and
  manifolds are not required on vessels contracted for prior to November
  19, 1952.
\5\ Not required on vessels less than 300 gross tons (except on an
  international voyage) using fuel with a flashpoint higher than
  110[deg] F., where the space is normally manned.
\6\ Not required on vessels contracted for prior to November 19, 1952.
\7\ Not required on vessels less than 300 gross tons nor on vessels
  contracted for prior to November 19, 1952, except when fuel, including
  starting fuel, has a flashpoint of 110 [deg]F. or less.
\8\ When fuel with a flashpoint of 110 [deg]F. or lower is used, the
  space containing the fuel tanks must be protected by a carbon dioxide
  system or carbon dioxide-alternative system as described in 46 CFR
  subpart 95.16.

[[Page 8443]]

     (b) The arrangements and details of the fire detecting systems 
must meet the requirements in subparts 76.25 through 76.33 of this 
part.
    26. Revise Sec.  76.10-5(h) to read as follows:

Sec.  76.10-5  Fire pumps.

* * * * *
    (h) If a vessel uses main or auxiliary oil fired boilers or 
internal combustion propulsion machinery, when two fire pumps are 
required, this equipment must be located in separate spaces and the 
arrangement of pumps, sea connections, and sources of power must be 
arranged to ensure that a fire in any one space will not put all of the 
fire pumps out of operation. However, in vessels of less than 300 feet 
in length, when it is shown to the satisfaction of the Commandant that 
it is unreasonable or impracticable to meet this requirement due to the 
size or arrangement of the vessel, or for other reasons, the 
installation of a total flooding carbon dioxide or clean agent 
extinguishing system may be accepted as an alternate method of 
extinguishing any fire that affects the powering and operation of at 
least one of the required fire pumps.
    27. Add a new Sec.  76.15-50 to read as follows:

Sec.  76.15-50  Lockout valves.

    (a) A lockout valve must be provided on any carbon dioxide 
extinguishing system protecting a space over 6,000 cubic feet in volume 
or a space 6,000 cubic feet or less in volume that does not have a 
horizontal escape.
    (b) The lockout valve must be a manually operated valve located in 
the discharge manifold prior to the stop valve or selector valves. When 
in the closed position, the lockout valve must provide complete 
isolation of the system from the protected space or spaces, making it 
impossible for carbon dioxide to discharge in the event of equipment 
failure during maintenance.
    (c) The lockout valve design or locking mechanism must make it 
obvious whether the valve is open or closed.
    (d) A valve is considered a lockout valve if it has a hasp or other 
means of attachment to which, or through which, a lock can be affixed, 
or it has a locking mechanism built into it.
    (e) The lockout valve must be locked in the closed position 
whenever maintenance is performed on the extinguishing system. The 
master must ensure that the lockout valve is locked in the open 
position when maintenance is complete and the system is returned to 
operable condition.
    (f) Lockout valves added to existing systems must be included in 
the system Type Approval or acceptable to the Marine Safety Center
    (g) Vessels in operation on [EFFECTIVE DATE OF RULE] must comply 
with the lockout valve requirements of this section not later than 
[DATE 5 YEARS AFTER EFFECTIVE DATE OF RULE].
    28. Add a new Sec.  76.15-60 to read as follows:

Sec.  76.15-60  Olfactory additives.

    (a) Each carbon dioxide extinguishing system must have an approved 
odorizing unit to produce the scent of wintergreen, the detection of 
which will serve as an indication that carbon dioxide gas is present in 
a protected area and any other area into which the carbon dioxide may 
migrate.
    (b) Vessels in operation on [EFFECTIVE DATE OF RULE] must comply 
with the requirements of this section not later than [DATE 5 YEARS 
AFTER EFFECTIVE DATE OF RULE].
