Explosion hazards are minimized through the following measures:
a. Liquid propane gas tanks/cylinders are stored safely (outdoors, posted with warning including no-smoking signs, away from exits)
b. Acetylene tanks are stored safely (away from flammable chemicals, sources of heat)
c. Explosion-proof lights and switches are installed in chemical storage or warehouses containing flammable materials (enclosed in rubberized, air-tight housing)
