This document is a recommended guide of good practice to be used on a voluntary basis by all who supply, use, store, or transport refrigerant recovery cylinders. Serious personal injury and property damage can result from improperly filled cylinders.

The following precautions are recommended for the safe handling of used refrigerant:

– Use personal protective equipment such as side shield glasses, gloves, safety shoes, and hard hat when filling and handling cylinders;

– Avoid skin contact with liquid refrigerant since it can cause frostbite;

– Be aware that inhalation of high concentrations of refrigerant vapor is harmful and can cause heart irregularities, unconsciousness, or death. Since vapor is heavier than air, avoid low areas without suitable ventilation;

– Do not apply open flame or heat cylinder above 125 °F (52 °C); and

– Do not artificially cool cylinder.

Use only cylinders designed and marked for refrigerant recovery service. DO NOT REUSE cylinders intended for virgin refrigerant service. Make certain the cylinder is charged only with the refrigerant for which it is designated. DO NOT mix different refrigerants in the same cylinder.
