Automotive

Combustible gases, flammable solvents and fuel vapors, which can be a threat to employees and equipment, are present in various processes in automobile manufacturing.
Fuel is distributed into the automobile's fuel  tank at the end of production. Fuel can spill into a sump , where it can be a highly dangerous risk of fire or explosion. 
In electrostatic spray booths, the electrically charged powder paint  is susceptible to explosions that can cause fires.
