AHRI white paper: reports of R134a contaminated with R40 and other refrigerants.

Author(s) : AHRI

Type of article: Periodical article

Summary

Counterfeit R134a, containing R40 (methyl chloride or chloromethane), has been found in mobile air conditioners, stationary air conditioning, and transport refrigeration systems in many countries. For your personal safety and to avoid serious injury or death, special care must be taken when accessing the service ports to sample or work on systems that are not functioning properly or have been serviced by others. R40 chemically reacts with aluminum inside HVACR systems to generate highly reactive and/or toxic compounds, and exposure of the system’s contents to air and/or moisture could result in production of a strong acid and violent chemical reaction. Several container systems have exploded at service facilities, some resulting in fatalities. Some of these systems were found to contain R40 and/or other unacceptable substances.
