fuel storage tank vents
fuel gas pipelines
safety storage cabinets for paint, aerosol cans, and other flammable mixtures
the exhaust system of internal combustion engines
Davy lamps in coal mines
overproof rum and other flammable liquors[2].
(I think its not flame screen but flame arrestor screen)
Flame arrestor screen: A mechanical device installed on a storage tank or portable container nozzle designed to prevent the build up of flammable vapors and quickly extinguish a fire in the container by rapidly dissipating heat from the fire. It is made of double mesh wire and extends inside the container from the nozzle.
