       Honeywell Reaffirms Safety of New Low-GWP Automotive Refrigerant

MORRIS TOWNSHIP, N.J., July 10, 2013 /PRNewswire/ --Honeywell (NYSE: HON)
issued the following statement following recent media reports that falsely
claim the new low global warming potential (GWP) refrigerant HFO-1234yf is
less safe than the commonly used, high global warming refrigerant, HFC-134a:

"Many automakers have engineered their vehicles for HFO-1234yf because they
saw it as the safest, most cost-effective and environmentally-friendly
solution to comply with the EU Mobile Air Conditioning (MAC) Directive. Their
selection was backed by comprehensive testing conducted over a three-year
period under the Cooperative Research Program (CRP) of SAE International,
sponsored by 15 global automakers, including all leading German automakers.
SAE's study – recently reaffirmed by another CRP – concluded that HFO-1234yf
is safe for use in automobile applications.

"It is unfortunate that in the wake of controversy over implementation of the
MAC Directive, caused by a single automaker's public declaration that it will
not comply, media reports have surfaced misinformation about HFO-1234yf.
Honeywell would like to set the record straight on two important points:

  oIndustry safety experts agree that appropriate vehicle design vastly
    minimizes any refrigerant combustion risks. SAE has concluded that it is
    300,000 times more likely that a vehicle would experience a fire for
    reasons unrelated to the refrigerant than due to its refrigerant – and
    that there is no significant risk caused by using HFO-1234yf. Independent
    research has demonstrated that both HFC-134a – the very safe automobile
    refrigerant in use for the past two decades – and HFO-1234yf, when mixed
    with oil in automotive air-conditioning systems, can combust when sprayed
    on extremely hot surfaces. Claims that HFC-134a cannot burn are false. To
    read SAE's report, visit
  oFluorocarbons such as HFC-134a and HFO-1234yf are alike in the sense that
    that they can emit small quantities of hydrofluoric acid (HF) when they
    combust. SAE research demonstrated these quantities are well below
    thresholds that would affect human health and that, again, there is no
    significant risk caused by using HFO-1234yf. Fluorocarbon refrigerants
    have been used safely in automobiles for six decades, and there is no
    reason to believe HFO-1234yf will be different.

"Under the hood of an automobile are many flammable materials, including
gasoline or diesel, lubricating oils, and brake and transmission fluids.
Proper vehicle design allows these otherwise hazardous materials to be used
safely by billions of people in automobiles every day to the benefit of
society as a whole. For a video on this topic, which includes a comparison of
HFO-1234yf vs. HFC-134a and other materials, visit

"Honeywell continues to stand firmly behind the safety of HFO-1234yf, and it
will continue to supply its customers to enable them to comply with the MAC
