As the HVACR industry transitions away from HFCs such as R-410A to alternative refrigerants that are mildly flammable (A2L), it is not surprising that those who will be handling – or teaching about -- ...

NFPA’s online Flammable Refrigerant Training for the Fire Service is available at no cost. Those that successfully complete the training will receive a certificate of completion.

The 2024 international building code update will likely include the use of these mildly flammable refrigerants, but some states are not waiting. Instead, many are updating their state codes to allow ...

Explore the shift to A2L refrigerants in HVAC systems and their impact on environmental regulations and design standards.

The type of refrigerant currently used in HVAC systems is being phased out. The 2020 American Innovation and Manufacturing Act directed manufacturers to make air conditioners that use A2L ...

More than a dozen chemical blends could serve as alternative refrigerants that won't heat the atmosphere as much as today's refrigerants do, or catch fire, according to a new computational study.

COLUMBIA, MD (May 6, 2021) - UL Firefighter Safety Research Institute (FSRI) announced today the release of the new “Firefighter Safety and Flammable Refrigerants” online training course. This ...

Columbia, Maryland, May 6, 2021 – UL Firefighter Safety Research Institute (FSRI) announced today the release of the new “Firefighter Safety and Flammable Refrigerants” online training ...

Potential refrigerants with the lowest GWPs include ammonia, commonly used in large industrial refrigeration systems but toxic and slightly flammable, and dimethylether, a propellant and potential ...

The U.S. Environmental Protection Agency is advising truck owners to avoid hydrocarbon refrigerants being sold as inexpensive substitutes for HFC-134a and CFC-12. Marketed under such names as OZ ...

That's partly because U.S. building codes prohibit installing a flammable refrigerant in an occupied space, he said. Building codes, he said, are the single largest hurdle in the transition.

Modern refrigerators now use a refrigerant that is considered highly flammable. Social media trends have more people keeping make-up that needs refrigerated in their bedrooms.
