"Two electricians suffered singeing burns when residue in an
electrical switchgear cubicle was ignited shortly after an electrical
contact cleaner aerosol had been used. In another case
solvent from a pressure can was ignited by a heat gun. A safety risk
exists where any aerosol container with flammable contents is used in a
confined space or near an ignition source, whether this is electrical
switchgear or some other source of raised temperature.
As they are
used so frequently, it is important to refer to information on the can
itself or preferably to the appropriate material safety data sheet
regarding the flammability of the contents or any other restrictions on
usage. Some material safety data sheets state that the aerosol container
must not be used in confined spaces or may burst if exposed to
temperatures exceeding 50°C.Incorrectly used or stored aerosol containers may
represent a safety risk. It is important that material safety data
sheets are available" Courtesy Queensland Government - department of mines
