134A with Maxifridge LPG???

EPA requests information on the refrigerants Enviro-Safe, Red Tek,
Maxi-Frig, ES-12A, and Auto Cool. EPA has received numerous inquiries
regarding the SNAP acceptability of the above refrigerants for use in
motor vehicle air conditioners (MVACs). Materials disseminated through
mailings and the internet (Air Docket A-91-42, item IX-B-60) have made
consumers question whether the products listed above are acceptable
substitutes under the SNAP program for CFC-12 (R12 or freon) and other
ozone-depleting CFC-12 substitutes. Under Section 612(e) of the CAA,
any person who produces a substitute for a CFC is required to submit
information to EPA at least 90 days before the substitute is introduced
into interstate commerce. The refrigerants listed above have not been
submitted to EPA for review under the SNAP program. Therefore, the
Agency believes that they cannot be sold as replacements for CFC-12 or
other ozone-depleting CFC substitutes in MVACs.
Additionally, based on advertising materials, Material Safety Data
Sheets (MSDSs) and independent laboratory testing (Air Docket A-91-42,
item IX-B-60), EPA believes the refrigerants listed above may be
flammable hydrocarbon-based blends. In June 1995, flammable
refrigerants were listed as unacceptable as substitutes for CFC-12 in
MVACs because a comprehensive risk assessment on the use of flammable
refrigerants had not been submitted to EPA (60 FR 31092). EPA welcomes
the submission of such a risk assessment. However, until EPA receives
sufficient information on the potential risks of flammable refrigerants
in MVACs, all flammable refrigerants are unacceptable as substitutes
for CFC-12 and ozone-depleting freon substitutes in MVACs, unless
specifically listed as acceptable. Consumers should also be aware that
the following 19 states ban the use of flammable refrigerants in MVACs:
Arkansas, Arizona, Connecticut, Florida, Idaho, Indiana, Iowa, Kansas,
Louisiana, Maryland, Nebraska, North Dakota, Oklahoma, Texas, Utah,
Virginia, Wisconsin, Washington, and the District of Columbia. For
further information about flammable refrigerants, see EPA's web site
(http://www.epa.gov/ozone/snap/refrig...hc12alng.html).
EPA requests information on the composition and the flammability of
Enviro-Safe, Red Tek, Maxi-Frig, ES-12A, and Auto Cool. We also would
welcome any formal risk assessment on these refrigerants.
