HFO-1234yf is a highly efficient, low-global-warming refrigerant that was developed as a direct replacement to HFC-134a in mobile air-conditioning applications. Compared with HFC-134a, HFO-1234yf offers a 99.7 percent improvement in global warming potential and far exceeds the European Union Mobile Air Conditioning (MAC) Directive requirement.
Under rare conditions, HFO-1234yf exhibits mild flammability, at levels significantly lower than highly flammable materials already present under the hood of an automobile, including motor oil, automotive transmission fluid, radiator antifreeze, brake fluid, and compressor lubricant – not to mention fuel.

SAE International's previous research projects have addressed the issue of flammability, employing proven and universally accepted fault-tree risk assessment techniques to evaluate the real-world possibility of a fire and human impact. SAE International said in its latest statement that it has expanded its fault-tree assessment in the new CRP to "ensure that newly-identified information and testing from each of the OEMs is incorporated."
As part of SAE International's programs, internationally recognized laboratories – including Hughes Associates Inc. and France's Institute National de l'Environment Industriel et des Risques (INERIS) – conducted extensive testing on flammability and safety, and all concluded that HFO-1234yf is safe for use in automobiles.Honeywell ( www.honeywell.com) is a Fortune 100 diversified technology and manufacturing leader, serving customers worldwide with aerospace products and services; control technologies for buildings, homes and industry; turbochargers; and performance materials.
