A fire retardant spray is a type of fire extinguisher that is usually contained in a pressurized canister and sprayed onto a burning surface. It is very effective against small fires and can be used to prevent a fire from spreading. Almost all major infernos started off as small fires, usually from something like a burning cigarette butt or an electric spark. If left undetected, the fires grow very rapidly and if they catch onto things like dry grass or wall paint, it becomes too difficult to put them out. Fire retardant sprays are supposed to be used in common places where fires are very likely to occur. Some are small enough to carry around in your glove compartment while others are a little bigger and can be left in the house or around it for easy access. Fire retardant sprays are very common in places like gas stations, bakeries, welding shops, and tobacco houses. These places are extremely prone to fires due to the nature of activities that take place there. No matter how careful you are, nobody is ever safe from fires. A fire could start in your own home or even a car and when it does, it is best to be prepared. You can always have a fire retardant spray around you in case an emergency occurs. The chemicals or gases they contain usually put out fires very quickly. This article discusses some factors you should consider when buying a fire retardant spray.
One thing you have to consider is the size of the spray. Smaller canisters are meant for portability and are convenient for cars and motorcycles. Engine fires usually start very small and are also quite easy to detect. This means that you can put them out with a smaller volume of fire extinguishers. Larger canisters are meant for places where a fire can spread very fast, for example, a welding shop or a gas station. The items in such places are highly flammable and the tools used are also extremely dangerous. The bigger the canister, the harder it will be to carry around however, bigger canisters also have a lot of fire extinguishing chemicals in them and can put out much larger fires than regular-sized canisters.
You also have to consider the chemicals present in the fire extinguisher. Common fire extinguishing chemicals include carbon dioxide, water, inert gases, and composites of these three. Many other substances can also be used to extinguish the fire but the ones mentioned above are the most common. Fire extinguishers that use inert gases might be a bit expensive and they are not appropriate for all situations. Water is a better item to use where there are people inside a burning building for example because carbon dioxide could suffocate them.
Finally, consider the cost of the fire extinguisher. As mentioned earlier, inert gases are more expensive than say water or carbon dioxide. Water-based extinguishers are the cheapest but will not work in places like gas stations as the flammable liquids float above water.
