When you disrupt or remove an element, the fire cannot sustain itself. Overall, Halon is safe around humans and can be used in occupied spaces. Halon suppression systems became widely properly because Halon is a low-toxicity, chemically stable compound that does not damage sensitive equipment, documents, and valuable assets.
Halon fire suppression systems are still used in places like computer and communication rooms and in several military applications, including on ships, aircrafts, and tanks. The FAA also continues to recommend Halon fire extinguishers for aircrafts because of its effectiveness and ability to be used in closed spaces.
There are two sources for Halon to recharge your halon fire extinguisher or fire suppression system. The first is from distributors that have stored quantities of Halon for sale. It is seen as the most ideal fire extinguisher but for many locations. As a clean agent, it is an electrically and non-conductive firefighting tool. It is also ideal for volatile and gas-related fires. In many situations, this is ideal. The key benefit of Halon is its ability to extinguish a fire without damaging the assets it is protecting.
Temperature reduction occurs, whenever a non-reactive gas is added to a flammable gas, because the heat liberated by the reaction of oxygen molecules with a fuel source must be distributed into the overall environment.
The rate of the combustive chemical reaction decreases rapidly with reductions in temperature and, if the concentration of added inert gas is high enough, the flame chemistry fails altogether. Halon gas mixtures are not only inert but of low temperature when released from their pressurised state. Dilution is a simple matter of reducing the collision frequency of the oxygen and fuel source so that there is a reduction in chemical reaction rates.
The magnitude of this effect, however, is relatively small compared to chemical inhibition and thermal effects, the former of these being the predominant one. The toxicity of the Halon gases, especially the combination which makes up Halon , is such that use in confined spaces requires care to minimise any inhalation of the discharged gases.
Guidance for Halon Emissions Reduction Rule technician training and proper disposal. On January 1, , production and import of virgin halons were phased out in the United States. Since that time, recycled halons are the only supply of halons in the United States for specialty fire suppression applications. While alternatives are available for most halon-based fire extinguishing applications c, halons are still employed for important applications such as on civil aircraft, in legacy military systems, and for oil and gas exploration.
Sources of recycled halons include stockpiles and recovered agent from cylinders collected from decommissioned systems both in the United States and abroad.
Management of halons in the United States over the last several decades combines strong collaboration by industry, government, and key users, effective regulations to reduce emissions, a smooth transition to safe alternatives through revisions to industry standards, voluntary industry codes of practice, maintenance of halon banking, and government halon reserves.
Commercial recyclers buy halon from decommissioned equipment, reclaim it to industry specifications and sell it into important, continuing uses such as aviation, military, and oil and gas exploration. EPA regulations address the import, export, handling, and disposal of halons , , and and equipment containing them.
The regulations cover the following:.
