Seven burning questions about mildly-flammable refrigerants
Concerns about global warming are strong motivation to adopt new, lower global warming potential (GWP) halogen refrigerants that break down quickly in the atmosphere. This reactivity can present new hazards if these mildly-flammable refrigerants leak into residences where ignition sources are present. Seven questions about these refrigerants are addressed to offer insight into flammability test methods, ignition source viability, leak detectors, and hydrogen fluoride (HF) hazards.
