Physical Properties of Novec 1230 Fluid

• Agent disperses as a gas
• No residue
• High density
• Water Insoluble
• High dielectric strength
• Liquid at room temperature
• Agent super-pressurized with N2 in cylinder

10
Extinguishing Mechanism
The Fire Tetrahedron
Removing one of the required components for fire
or disrupting the balance between them can cause
a fire to extinguish
Inert gases extinguish primarily via oxygen
depletion
halon extinguishes primarily via interruption of
the combustion chain reaction
Novec 1230 Fluid extinguishes primarily via
cooling removing heat from the fire

Atmospheric Lifetime
Controlling Factors for FK-5-1-12
Oxidation ? Reactivity with OH Requires
high reaction rate to produce very short
lifetime
Rain Out ? Dissolution and Deposition Require
s high water solubility and low volatility
Photolysis ? UV Absorbance and Dissociation
Requires strong absorbance in the near UV
to produce short lifetime

Atmospheric Degradation Mechanism
C2F5C(O)CF(CF3)2
"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
32

• 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, 600 AM, 2009
34
(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
42

• 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

43
Environmental Need

Environmental Need

• Phase-out of HGWMs (High Global Warming

• HFCs
• EU (European Union)
• - Austria Banned before 2008
• - Denmark - Banned before 2007
• - Germany Initial proposal underway
• - Norway Enacted tax (72 USD) per kg

United States Environmental Activity
H.R. 2454 American Clean Energy and Security
Act, Section 619 (Passed June 2009) Senate
Anticipate activity yet in 2009 California
Increased pressure to limit use of HFCs in fire
suppression
46
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?
50
Why Differentiate?

1. Low impact alternatives are being sold into the
   market including
2. Inert gases (Introduced 1994 38 market share)
3. Fluoroketones (Introduced 2004 19 market
   share)
4. Water mist (Introduced early 1990s 5 market
   share)
5. The remaining 38 of the systems using HFCs for
   fire suppression could be phased out immediately
   without compromising life or property.
6. 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.
