What are the different classes of fire extinguishers and how do they differ?

A: There are four different classes of fire extinguishers that are used in different scenarios. They are classified as A, B, C and D. Class A fire extinguishers are ideal for putting out fires that start from ordinary combustibles including wood and paper. Class B fire extinguishers are ideal for flammable liquids such as oil, gasoline and grease. Class C extinguishers are for electronics and Class D extinguishers are used for flammable metals.



How long do fire extinguishers last?

A: You’ll want to check the date of manufacture before use to make sure the fire extinguisher is still functional. Most fire extinguishers need to be refilled or refurbished every 5-6 years. Take the time to check your fire extinguishers on a monthly basis in case you need to use it unexpectedly. The last thing you want is to try to use a fire extinguisher that is not in working order!



How do I know if a fire extinguisher is not safe?

A: It can be difficult to determine if a fire extinguisher is safe, but a common indicator is the pressure gauge. Make sure that the pressure indicator is pointing to the green zone between two different red zones. If you notice that the indicator is in either of the red zones, this means that it needs to be serviced as soon as possible.



Is it dangerous to drop a fire extinguisher?

A: Because fire extinguishers are pressurized, dropping one may result in damage to the functionality of the extinguisher. If you accidentally drop one, make sure that you keep it in an isolated area and to contact a professional to handle it.
