Issue 2 Connecticut Apartment Association Gazette Est. 2016 Containers that have held ammable or combustible liquids can remain explosive even after the liquid has been removed. e liquid in the container is replaced by air which mixes with the hazardous vapors. is combination can be explo- sively ignited by a spark or heat. In fact, these containers are normally more explosive than a full container. How many times have you seen a 5 gallon pail or a 55 gallon drum being used as a welding or grinding stand? is is very dangerous. Any sparks produced could ignite the vapors. Also, the torch ame, heating the container, could ignite the vapors within the drum. e auto-ignition temperature of many ammable vapors is far below the melting point of steel. Some auto-ignition points are as low as 450 degrees. • Never attempt to do any hot work on a container unless it has been thoroughly and properly cleaned. • Steam, followed by a caustic soda wash and fresh water rinse, is the best method. • Dry with warm circulating air. • Inspect the inside for cleanliness. If it is not clean, the procedure will need to be repeated. • Use a combustible gas indicator to test the container for the presence of ammable vapors immediately before beginning the hot work. Never assume the container is clean enough. • Be certain! • As an added precaution, ll as much of the container as possible with water. • Inert the remaining space with nitrogen or carbon diox- ide. Complete these steps only in a well ventilated space. Once all this has been done, the hot work can be performed with a reasonable degree of safety. e key is a clean container that has been veri ed to be free of vapors. ere is no other safe way. Don't forget, vapors can travel to a source of ignition that is located well away from the work area. For this reason, always replace the cap on any container. With the cap o there is a greater likelihood of product vapors escaping into the air where they could be ignited, or where a source of ignition could be accidentally introduced into the opening. THAT CONTAINER ONLY LOOKS EMPTY!
