Are plastic tanks approved for use in fire protection systems?
A. Some local jurisdictional authorities allow the use of plastic tanks for fire protection, especially under hard access conditions. Plastic is a flammable material that loses structural integrity when exposed to heat. NFPA does not recognize polyethylene as a suitable material for fire protection storage. BH Tank recommends that every effort be made to use an approved material for fire protection. If a purchaser insists on plastic tanks for economical or access reasons, a letter of approval from the local fire marshal is recommended. Insurance companies may not pay for loses incurred due to fire if non-approved materials are used in fire protection systems.
