Fire Extinguisher Training and Safety
To fully understand how to use a fire extinguisher and how they work, you will first need to understand the basics of a fire. Fire is the result of a rapid chemical reaction that occurs with oxygen and a combustible material. The result of this chemical reaction is the flames, smoke, and heat associated with fire. For fire to exist, these things must all be available at the same time:
- Large enough oxygen supply to start and then sustain combustion and fire growth
- Enough heat at the source of the fire to raise the material to its to the point that it ignites and burns
- Some sort of fuel for the fire to consume and feed off of-some kind of combustible material
- The chemical reaction seen in the flames, smoke, and heat that is known as fire
How a fire extinguisher works
Portable fire extinguishers are a must have for any business, but especially those that deal with hot temperatures, electrical equipment, or other situations that are more prone to fire outbreaks. Fire extinguishers apply an extinguishing agent which eliminated one or more of the four elements needed for the fire to be sustained. Some extinguishers cut off oxygen to the fire and others work by cooling the temperature or removing the dry combustible element of the material being burned. When you pull the trigger handle of an extinguisher, the extinguishing material shoots out of the nozzle and can be directed at the flames.
Types of extinguishers
All portable fire extinguishers must be approved by a nationally recognized testing laboratory to verify compliance with applicable standards -29 CFR 1910.157(c). Different types of fire extinguishers are better against certain types of fires. Some fires are classified as electrical and other could be classified as liquid fires or general combustible fires. The three types of fire extinguishers most commonly seen are: air pressurized water, CO2 canisters, and dry chemical. A trained fire extinguisher expert can help you determine what type of fire extinguishers are best for your business needs and the experts at Risk Safety Services offer specialized training courses too for fire risk training and extinguisher use.
