How to Choose a Fire Extinguisher

Many people consider the importance of preparing for a fire at home, but it is equally crucial to do the same in the workplace. Recognize that fire hazards and accidents occur; it’s best to have the tools needed to be prepared for any situation.

Everyone understands how critical it is to have fire extinguishers present in a building, however it’s important to note that different types of buildings require different types of fire extinguishers.  Use the information below to ensure you are choosing the right fire extinguisher for your facility’s needs.

Types of Fire Extinguishers

To combat the different types of fires that may arise, there are various types of fire extinguishers.  Each extinguisher has its own unique characteristics and capabilities.

The three main types of fire extinguishers are:

1. Water Extinguishers – these units are filled about two-thirds with water and then pressurized with air.
2. Carbon Dioxide (CO₂ ) Extinguishers – in this style, the extinguishing contents are pressurized with CO
3. Dry Chemical Extinguishers – these extinguishers discharge a blanket of fine powder, which creates a break between the fuel and the oxygen in the air.

If you’re unclear about which type of extinguisher fits your building’s needs, consult a third party like Fire Monitoring of Canada to review your options.

How To Use A Fire Extinguisher
