Static ignition source

Spills or overflows that occur while filling containers, drums, trucks, or tanks will create a fire hazard. If such a spill should occur, prompt action is necessary to remove possible sources of ignition such as automotive engines. If the spill occurs adjacent to fired heaters or other static ignition sources, then consideration should be given to shutting them down until the spill has been cleaned up and/or foam has been applied to the spilled materials.

A common ignition source within chemical plants is sparks resulting from static charge buildup and sudden discharge. Static electricity is perhaps the most elusive of ignition sources. Despite considerable efforts, serious explosions and tires caused by static ignition continue to plague the chemical process industry. 

Ignition arises from a wide variety of sources, including static electricity, hot surfaces, sparks, open flames, and electric circuits. Ignition sources are elusive and difficult to eliminate entirely, although efforts should always be made to reduce them. 

Regarding electrostatic ignition sources, see the subsection Static Electricity, later. In addition, see CENELEC CLC/TR 50404, Electrostatics—Code of Practice for the Avoidance of Hazards due to Static Electricity, June 2003.
