This comment follows a similar comment for 4.1.4.4 for inert gas agent containers. Together the proposed revisions to 4.1.4.4 and 4.1.4.5 state what is required in terms of providing means of pressure measurement for which types of agent containers.

A minimum concentration of 85 percent of the adjusted minimum design concentration shall be held at the highest level of combustibles for aperiod of 10 minutes or for a time period sufficient to allow for response by trained personnel, whichever is greater .


Adequate protection from clean agent systems should be provided for a minimum time period of 10 minutes. The First Draft Revision allows for protection to be designed and provided for a shorter period replying on the human element to intervene, defeating the purpose of fixed protection. If the response time from trained personnel is extended or trained personnel no longer are available from the original design time period at a later date, there may be inadequate protection provided to the occupancy. In addition this revision will effect the listings with FM Approval as the Class 5600 have a 600 second time limit for extinguishment in the Class A fire tests. Fires may not be extinguished if the minimum time period is removed.

Public Comment No. 16-NFPA 2001-2013 [ Section No. A.1.6 ]

A.1.6

Many factors impact the environmental acceptability of a fire suppression agent. Uncontrolled fires pose significant impact by themselves. Allextinguishing agents should be used in ways that eliminate or minimize the potential environmental impact [see Table A.1.6]. Generalguidelines to be followed to minimize this impact include the following:

(1) Not performing unnecessary discharge testing

(2) Considering the ozone depletion and global warming impact of the agent under consideration and weighing those impacts against thefire safety concerns

(3) Recycling all agents where possible

(4) Consulting the most recent environmental regulations on each agent

The unnecessary emission of clean extinguishing agents with the ODP, the GWP, or both should be avoided. All phases of design,installation, testing, and maintenance of systems using these agents should be performed with the goal of no emission into the environment.

GWP is a measure of how much a given mass of greenhouse gas is estimated to contribute to global warming. It is a relative scale thatcompares the gas in question to the same mass of carbon dioxide whose GWP is by convention equal to 1.

It is important to understand that the impact of a gas on climate change is a function of both the GWP of the gas and the amount of the gasemitted. The U.S. EPA employed its vintaging model (U.S. EPA, Inventory of U.S. Greenhouse Gas Emissions and Sinks: 1990–2007) toestimate the emissions of greenhouse gases (GHGs) from various sources. This model indicated that fire protection emissions accounted for0.6 percent of total GHG emissions. For current U.S. emissions data, refer to the HFC Emissions Estimating Program (HEEP).

Section 1.6 of NFPA 2001indicates that "the effects of the agent on the environment shall be considered" and that furthermore agent selection shall include consideration of "potential environmental impacts." The current text in Section A.1.6 fails to provide relevant and current third party information related to the impact of HFC clean agents on climate change.

The proposed version of Section A.1.6 correctly points out that the impact of a gas on climate change is afunction of BOTH the GWP value and the amount of emissions, but then cites only emissions data - this does not address the concern of Section 1.6 which emphasizes that the effect or impact is the item to be considered. The proposed text provides the necessary data, from a third party independent source (the US EPA) related to the concern of Section 1.6 - the IMPACT of emissions.

A.4.1.4.1


19 of 32 6/13/2014 2:37 PM

Containers used for agent storage should be fit for the purpose. Materials of construction of the container, closures, gaskets, and othercomponents should be compatible with the agent and designed for the anticipated pressures. Each container is equipped with a pressurerelief device to protect against excessive pressure conditions.

The variations in vapor pressure with temperature for the various clean agents are shown in Figure A.4.1.4.1(a) through Figure A.4.1.4.1(m).

For halocarbon clean agents, the pressure in the container is significantly affected by fill density and temperature. At elevated temperatures,the rate of increase in pressure is very sensitive to fill density. If the maximum fill density is exceeded, the pressure will increase rapidly withtemperature increase and present a hazard to personnel and property. Therefore, it is important that the maximum fill density limit specifiedfor each liquefied clean agent not be exceeded. Adherence to the limits for fill density and pressurization levels specified in Table A.4.1.4.1should prevent excessively high pressures from occurring if the agent container is exposed to elevated temperatures. Adherence to the limitswill also minimize the possibility of an inadvertent discharge of agent through the pressure relief device. The manufacturer should beconsulted for superpressurization levels other than those shown in Table A.4.1.4.1.

With the exception of inert gas–type systems, all the other clean agents are classified as liquefied compressed gases at 70°F (21°C). Forthese agents, the pressure in the container is significantly affected by fill density and temperature. At elevated temperatures, the rate ofincrease in pressure is very sensitive to fill density. If the maximum fill density is exceeded, the pressure will increase rapidly withtemperature increase and present a hazard to personnel and property. Therefore, it is important that the maximum fill density limit specifiedfor each liquefied clean agent not be exceeded. Adherence to the limits for fill density and pressurization levels specified in Table A.4.1.4.1should prevent excessively high pressures from occurring if the agent container is exposed to elevated temperatures. Adherence to the limitswill also minimize the possibility of an inadvertent discharge of agent through the pressure relief device. The manufacturer should beconsulted for superpressurization levels other than those shown in Table A.4.1.4.1.
