"Photolysis of C2F5C(O)CF(CF3)2 in air gives CF3C(O)F and
COF2. CF3C(O)F will be incorporated into air/cloud/seawater
where it will undergo hydrolysis to give trifluoroacetic acid.
Similarly, COF2 will undergo hydrolysis to give CO2 and HF. At
the concentrations expected in the environment, none of
these degradation products is considered harmful.”
Taniguchi, et al., J. Phys. Chem. A, 2003, 107, 2674-2679
 FK-5-1-12 has undergone thorough environmental
assessment
 Atmospheric sink is photolysis leading to lifetime on
order of 5 days
 Degradation products not considered to be
environmentally harmful
 Short atmospheric lifetime leads to negligible direct
GWP
 Decomposition products lead to negligible indirect
GWP
 Compound is stable for handling and long-term
storage in systems
At this moment*, installations, worldwide, of
3M™ Novec™ 1230 Fire Protection Fluid have
prevented more than
28,685,202,000 lbs. of C02
equivalent future emissions
*Nov 1, 6:00 AM, 2009
(Extracted from the 3M Web Site) – The global warming
potential of a clean agent is expressed by the number of
pounds of CO2 it would take to equal the impact of the
discharge of one pound of the agent.
For example, HFC-227ea, the predominant HFC installed in
fire protection systems, has a GWP of 3220, meaning that
the discharge of one pound of HFC is equivalent to 3,220
pounds of CO2. By contrast, Novec 1230 fluid has a GWP of
1, about the same as naturally-occurring CO2.
As the installed base of Novec 1230 fluid begins to replace
HFC-227ea, the amount of CO2 equivalency that could
potentially be released to the atmosphere decreases
correspondingly. This counter, based on existing and
projected installations, represents the approximate amount
of CO2 equivalency being reduced at any given point in time
by the replacement of HFC-227ea with Novec 1230 fluid.

International Experience w/ HFCs
• Non-critical Halon systems were forced into
decommissioning in Europe by end of 2003
– Venting may have occurred at significant
levels
• Denmark has banned HFC use in fire suppression
• Switzerland only allows HFC use only if safety of
people cannot otherwise be assured
• European Union has not limited HFC use in fire
suppression systems
Kyoto Protocol
• Adopted in 1997 in Kyoto, Japan
• CO2, CH4, N20, HFCs, PFCs, SF6
• Worldwide differentiated target of 5.2% reduction in
GHG emissions between 2008-2012 (1990 levels)
• EU (-8%), Japan (-6%), U.S. (-7%, at +16%)
• No international policies and measures

Scope of U.S. Discussions
• Section 619 of HR 2454 addresses a wide range of
HFCs placing HFCs used in fire suppression (small
segment) along with refrigerants (huge segment).
• HFCs used for fire suppression include high GWP
materials: HFC 23; HFC-227ea; HFC-236fa and
HFC-125.
• HFCs used for fire suppression should be separated
from refrigerants in Section 619.

What Do The HFC Manufactures Say?
Why Differentiate?
1. Low impact alternatives are being sold into the
market including:
1. Inert gases (Introduced 1994 – 38% market share)
2. Fluoroketones (Introduced 2004 – 19% market share)
3. Water mist (Introduced early 1990’s – 5 % market share)
2. The remaining 38% of the systems using
HFCs for fire suppression could be phased out
immediately without compromising life or
property.
3. HFCs used for fire suppression represent a small
percentage of the total HFC Usage, but have a
disproportionate climate impact because of their
high GWP values.
