The National Propane Gas Association (NPGA) has issued a safety alert that may impact employers and employees at propane cylinder exchange and filling stations, as well as response personnel involved in methamphetamine raids and cleanup operations. The alert addresses the hazards of cylinders used in meth labs to store and use anhydrous ammonia. When the cylinder’s valve comes in contact with anhydrous ammonia, a “violent, unexpected expulsion of the valve” may occur, resulting in serious injury or death. Refer to the alert, or contact your local OSHA office for more information on properly handling and disposing of these cylinders.
