VARIOUS MEDIA OF FIRE PROTECTION ALTERNATIVES FOR HALON FLOODING AND LOCAL APPLICATION SYSTEMS TRADITIONAL FIRE PROTECTION AGENTS. Non-Halon fire protection materials such as dry chemical, CO2, water sprinklers, and foams to protect special hazards has been promoted as a means of replacing Halon use. The effectiveness of these traditional protection alternatives is dependent on the occupancy they are selected and designed to protect. The use of these traditional technologies should be given serious consideration as appropriate Halon replacements in occupancies where they are agreeable with the hazard. They also should be properly installed in accordance with applicable standards. Examples of traditional fire protection agents are as under:• Dry chemical • CO2 • Water sprinklers • Foams INERT GASES. Inert gases are designed to reduce the ambient oxygen concentration in a protected space to between 10-14% by utilizing a concentration of 35-40% by volume, a level that is breathable but will not support flaming combustion. These systems use inert gases such as argon, nitrogen, CO2 or a blend. These are applied in total flooding systems. Inert gases are electrically non-conductive, clean agents however due to excessive discharge times these are not recommended for areas where a rapidly developing fire can be expected. Due to the necessary concentrations, inert gases normally require a large tank storage area. It should be noted that fireextinguishing CO2, a by-product of other manufacturing processes, is not seen as adding to the greenhouse phenomenon. Advantages of inert gases • All inert gases are electrically non-conductive. • All are clean agents and leave no residue. Stops combustion at a breathable level. WATER MISTS. Water mist systems extinguish fires using small amounts of water released as tiny droplets, under low, medium or high pressure. The methods of extinguishment include cooling, oxygen dilution by steam expansion, the wetting of surfaces and turbulence effects. These systems use specially designed nozzles to produce much smaller droplets than that are produced by regular standard spray sprinkler systems. The smaller droplets are more effective at extinguishing fires; therefore, less water is needed. There are two types of water mist suppression systems, single and dual fluid systems. Both systems have been shown to be effective. In addition, when properly installed, they can effectively penetrate where deep-seated fires might develop. As a result, damage to water-sensitive equipment is minimized. Advantages of water mist systems:• Smaller droplets are more effective at extinguishing fires. • Less water is needed than standard spray systems. • Can effectively penetrate to deep-seated fires. • Damage to water-sensitive equipment is minimized.
AEROSOL GENERATOR SYSTEM. A category of new technology being developed and introduced are those related to fine solid particulate and aerosols. The different types of powdered aerosol systems include pyrotechnically generated aerosols and dry chemical halocarbon mixtures. Another unique category of fine particulate technology is gelled halocarbon/dry chemical suspensions. The effectiveness and the quality of the different types of powder can differ dramatically and must be closely monitored. Advantages of powdered aerosol:â€˘ Very high effectiveness/weight ratio. â€˘ No environmental concerns beyond those of the carrier gases. Fixed condensed aerosol fire extinguishing systems are used in normally unoccupied spaces as a total flooding fire suppression system for Class A (surface), Class B and Class C fires, to protect specific materials (especially hazardous materials) housed in fixed enclosures. The systems are considered alternatives to the Halon fire-extinguishing systems. The fixed condensed aerosol fireextinguishing systems are total flooding systems that consist of a condensed aerosol generator and an actuating mechanism. The systems do not require a piping distribution system. Features Environment effects Toxicity Pressurized Storage Costs
