6ltr Foam Fire Extinguisher - AFFF - FireShield

Product Information

These extinguishers are designed to spring into action when they detect heat. On the downside, their placing is crucial, since they could be set off erroneously when the ambient temperature reaches the trigger level. Although foam fire extinguishers are recommended for all business premises and residential properties, there are a few pros and cons of the extinguisher type that are worth considering. They are mainly water based, with a foaming agent so that the foam can float on top of the burning liquid and break the interaction between the flames and the fuel surface. Fire extinguishers should ideally only be used by someone who has been trained to do so – and the following text does not count as training. Moreover, a fire extinguisher should only be activated once the fire alarm has been triggered and you have identified a safe evacuation route. Evacuate the building immediately if you still feel unsure about using a fire extinguisher or if doing so is clearly the safest option.

The way you use a foam extinguisher depends on the type of fire you’re extinguishing. However, regardless of the fire, the first thing you do in every instance is to remove the safety pin. When extinguishing flammable liquid fires and flammable solid fires, never spray directly at the flames. Instead, follow these steps: Also, if you don’t have the appropriate fire extinguisher training and you don’t feel confident in using the extinguisher, the safest choice is to evacuate the building alongside everyone else and let the firefighters handle the problem. This fire type is commonly started by a gas leak or faulty industrial equipment. The only safe way to extinguish a Class C fire is by using a dry powder extinguisher. According to the standard BS EN 3, fire extinguishers in the United Kingdom as all throughout Europe are red RAL 3000, and a band or circle of a second color covering between 5–10% of the surface area of the extinguisher indicates the contents. Before 1997, the entire body of the fire extinguisher was color coded according to the type of extinguishing agent.

Air-pressurized water (APW) cools burning material by absorbing heat from burning material. Effective on class A fires, it has the advantage of being inexpensive, harmless, and relatively easy to clean up. In the United States, APW units contain 9.5 litres ( 2 + 1⁄ 2USgal) of water in a tall, stainless steel cylinder. In Europe, they are typically mild steel, lined with polyethylene, painted red and contain 6–9L (1.6–2.4USgal) of water. There are several class D fire extinguisher agents available; some will handle multiple types of metals, others will not. Bigger fires can be highly destructive and dangerous, not to mention expensive. The worst-case scenario is loss of life and serious injury, but even if this is avoided, fire damage represents a serious and expensive problem, even in smaller fires. Expect your insurance company to go through your fire safety practices with a fine-tooth comb before paying out if you are claiming as a result of a fire. Insurance companies know they can often void a policy based on a disregard for fire safety guidelines. While you might be concerned with the prices of fire extinguishers, the cost of this simple piece of equipment is far outweighed by the potential legal costs or the reparations you may have to pay as a result of non-compliance. Next, the foam then forms on top of the burning materials, cutting off oxygen, and eventually extinguishing the fire completely. When used on liquid fires, the foam floats on top of the burning liquid, making it easy to extinguish the fire. Unless you can safely disconnect the electrical current (or if your foam fire extinguisher is 35000 Volt tested), you should not use a foam fire extinguisher on an electrical fire.

Ternary eutectic chloride (T.E.C.) dry powder is a dry powder invented in 1959 by Lawrence H Cope, [34] [35] a research metallurgist working for the UK Atomic Energy Authority, and licensed to John Kerr Co. of England. It consists of a mixture of three powdered salts: sodium, potassium and barium chloride. T.E.C. forms an oxygen-excluding layer of molten salt on the metal's surface. Along with Met-L-X (sodium chloride), T.E.C has been reported [36] to be one of the most effective agents for use on sodium, potassium, and NaK fires, and is used specifically on atomic metals like uranium and plutonium as it will not contaminate the valuable metal unlike other agents. T.E.C. is quite toxic, due to the barium chloride content, and for this reason is no longer used in the UK, and was never used in the US aside from radioactive material handling glove boxes, where its toxicity was not an issue due their confined nature. T.E.C. is still widely used in India, despite toxicity, while the West uses chiefly sodium chloride, graphite, and copper types of powder and considers T.E.C. obsolete.

Alcohol-resistant aqueous film-forming foams ( AR-AFFF), used on fuel fires containing alcohol. Forms a membrane between the fuel and the foam preventing the alcohol from breaking down the foam blanket. There is no single fire extinguisher which works on all classes of fire.
