Abstract: Halon 1301 and 1211 are listed as scheduled substances in the 1987 Montreal Protocol because they are serious ozone destroyers. The Ozone Layer Protection Ordinance Cap. 403 was enacted in July 1989 to fulfil Hong Kong's international obligations. Although it has led to significant reductions of halon consumption since, progress in halon replacement has been slow primarily due to cost, building space constraints, and inconvenience brought by retrofit. Currently available alternatives to halon 1301 and 1211 are reviewed in this paper. A dimensionless cost model is developed to facilitate cost evaluation for the different replacements of halon 1301. Fire suppression effectiveness of halocarbon agents listed in NFPA 2001 are assessed, using a theoretical approach. Comparisons between the common alternatives are also made in terms of the environmental impact, health and safety, extinguishing effectiveness, and cost. Results from two case studies indicate that the life span and the age of buildings and fire protection systems significantly impact total cost. Elaborate strategies based on real situations may lead to considerable savings and benefits and accelerate the process of phasing out the halons.
