Environmental Quality (Halon Management) Regulations 1999, PU (A) 452.

Since halon is a substance that depletes the ozone layer, these Regulations prohibit its use, particularly in fire protection systems. In accordance with regulation 4, the use of any new portable halon fire extinguisher is prohibited. Regulation 5 prescribes that an owner or a person in control of halon shall inform the Director General of any halon in his possession. Regulation 12 establishes that an owner or a person in control of an existing halon fire extinguishing system shall ensure that halon is not discharged in any test or under any other circumstances unless the purpose is to prevent fire. Two schedules are attached. The second one lays down essential use criteria for the use of any portable halon fire extinguisher or fixed halon fire extinguishing system.
