Service Information Document Title: Function Group: Information Type: Date: Safety when working with air-conditioning refrigerant 870 Service Information 2014/3/19 Profile: SSL, MC90B [GB] Safety when working with air-conditioning refrigerant Safety rules WARNING     Wear tight-fitting goggles. Use rubber gloves and protect other areas of exposed skin (risk of frostbite). Avoid inhaling the refrigerant. Exposure to refrigerant can cause irritation of eyes, nose and throat. Inhaling concentrated refrigerant can cause cardiac arrest. Never mix R134a with air when checking for leaks. If something in the system generates a spark or the system is pressurized, the mixture may ignite. Use only refrigerant containers that are approved for the purpose when charging/draining refrigerant.    Never fill a refrigerant container to more than 60% of its gross weight classification. Sufficient volume must remain in order to handle the pressure increase due to volume changes caused by temperature changes, for example, sun exposure. Never expose a refrigerant container to temperatures above 50 °C (122 °F). Even a correctly filled container is an explosion hazard at temperatures above 50 °C (122 °F). Always perform service work in well ventilated areas. R134a is heavier than air and will therefore sink and concentrate in low areas, for example, a grease pit.
