`
`- Most Auto OEMs continue strong support of HFO-1234yf
`as the leading MAC alternative
`
`- Major milestones have been achieved through cooperative
`industry effort and open sharing of results
`
`— Toxicity/Environmental testing (Independent world class labs)
`
`— Risk assessments for flammability and health (SAE CRP—1234),
`(JAMA, European A||iance,)
`
`— System performance/LCCP evaluations (OEMs, JAMA, SAE CRP-
`1234)
`
`— Materials compatibility/durability testing (SAE CRP-1234-2, JAMA,
`OEMs, Tier 1s and 2s)
`
`— Registration (REACH, SNAP, ASHRAE, etc)
`
`
`
`HFO-1234yf Toxicity Summary H0"9)’W9"
`
`Recently completed developmental and reproductive studies
`have shown that HFO-1234yf will not be classified a
`developmental or reproductive toxin.
`
`HFO-1234yf has recently been approved as a Class A refrigerant
`by ASHRAE.
`
`HFO 1234yf WEEL was adopted at 500 ppm (8—hr TWA) by the
`
`AIHA WEEL Committee. AIHA Standards expects this
`
`assignment to be published in the 2009 set of WEELs.
`
`After independent review of all toxicology test results,
`DuPont and Honeywell have concluded that HFO-1234yf is
`safe to commercialize for use in MAC.
`
`Furthermore, industry risk assessments of various potential
`exposure scenarios have also concluded HFO-1234yf is safe for
`use in mobile AC applications.

`completeness issued July 8, 2008.
`
`If EPA has no significant issues, next steps are:
`
`— Draft a "Proposed Rule of Law" statement on HFO-1234yf and identify any
`conditions of use
`
`— Have the US OMB review and approve the Proposed Rule
`
`— Publish the Proposed Rule in the Federal Register
`
`— Have a public comment period for interested parties to make comments
`
`— Complete final EPA SNAP approval through publication of a Final Rule
`
`- US EPA Industry Update
`
`— EPA found no significant regulatory barriers to use of flammable refrigerants
`in Europe, Japan, or other countries when investigating use of HFC-152a.
`
`— Sixteen US states removed ban on flammable refrigerants in MAC, 3 remain.
`
`— Alliance of Automobile Manufacturers is working with support of EPA to
`remove those barriers for SNAP listed refrigerants.

`
`HFO-1234yf Flammability and
`Safety Standards Update
`
`ASHRAE SSPC 34 voted (1/09) to approve R-1234yf with Safety
`
`Classification A2 and requested immediate publication upon approval by
`
`ASHRAE Standards. Expect publication about March-April.
`
`ASHRAE SSPC 34 Flammability Subcommittee recommended
`
`publication public review of new 2L flammability classification group to
`
`be added to the Standard.
`
`ISO 817 draft Standard incorporating new 2L flammability classification
`
`approved at DIS stage and will be going out for p-member country vote
`
`in 2009. Expect publication as ISO standard in late 2010, HFO-1234yf
`
`ISO classification assignment aften/vards.
`
`SAE ICCC Committee developing Safety Standards for HFO-1234yf.
`
`New ISO Working Group (ISO/TC22NVG14) started to develop an ISO
`
`safety requirements standard for use of HFO-1234yf and CO2 for MAC;
`
`final publication targeted for 13* Half 201 1.

`
`
`US Codes and Standards
`As Applied to HFO-1234yf
`
`H°“e3'We"
`
`Summam
`
`- HFO-1234yf flammability characteristics are much more favorable than those of
`hydrocarbon gases or HFC-152a.
`
`US Codes for storage and handling of flammable liquefied gases provide specific
`
`treatment for hydrocarbon gases; need to develop guidelines for mildly flammable gases.
`
`US Electrical Codes exempt ammonia due to its mild flammability and high MIE.
`
`SAE working with UL to determine electrical equipment specifications for HFO-1234yf.
`
`Guidance from existing US Codes such as NFPA 58, NPFA 59A and NFPA 1 may be
`overly conservative with regard to HFO-1234yf on storage and handling.
`
`What's Next?
`
`- Work with NFPA, the refrigerants industry, and auto industry to properly incorporate mildly
`flammable refrigerant, HFO-1234yf
`
`- SAE J-Standards in various stages of completion to meet 2011 deadline
`
`- ASH RAE 34 and ISO 817 Classification standards for A2L refrigerants under development
