Fire extinguishers are usually the first line of defense against devastating blazes. For businesses, a commercial fire extinguisher is a critical piece of equipment that can save life and property in case of a fire emergency. Besides, the Occupational Safety and Health Administration (OSHA) requires employers to provide employees with portable fire extinguishing equipment that they can use to fight incipient stage fires in the workplace.
However, finding the best fire extinguisher can be a bit challenging as there are so many types of fire extinguishers available. Each type of extinguisher is created for a specific type of fire and may only be suited for certain situations. So, let’s have a quick look at the different classes of fires and fire extinguisher classes.
Classes of Fires
The classes of fire extinguishers are usually determined by fire classes which are categorized by what caused the fire. They are as follows:
- Class A: solid materials such as paper, fabric, wood, and some plastics
- Class B: gases or liquids like ether, gasoline, alcohol, or grease
- Class C: electrical failure from electronic equipment and appliances
- Class D: metallic substances like magnesium, titanium, sodium, and zirconium
- Class K: oil or grease fires that occur from cooking
Finding the best fire extinguisher for office or fire extinguisher for kitchen should be determined by the biggest fire risks in your facility.
Types of Fire Extinguishers
Here are some common fire extinguishers for your business.
- Carbon Dioxide Extinguishers: These types of extinguishers remove heat and oxygen from a fire. They work well in laboratories, but you can use them on Class B and C fires. They cannot also be used on fires caused by metals.
- Class K Wet Chemical Extinguishers: These are a must-have for any commercial kitchen. They are used to fight cooking fires and they extinguish gas fires by creating a foam blanket that prevents reigniting of the fire.
- ABC Fire Extinguisher: You can use this extinguisher on class A, B, and C fires. This extinguisher is an excellent choice for the office. It extinguishes fires using a special powder that easily puts out fires caused by electrical failure, burning liquids, and gases.
- Class D Extinguishers: These extinguishers do a great job putting out fires caused by metals including magnesium, titanium, sodium, and zirconium. These extinguishers use a sodium chloride agent to smother the fire.
- Water Mist Extinguisher: For buildings with expensive and sensitive machinery, you want to use water mist extinguishers. The ABC extinguishers tend to leave a huge mess and can damage expensive machinery. The water mist on the other hand is a lot gentler and will put out the fire without causing further damage to your valuable machinery.

What to Look for When Buying Fire Extinguishers
Finding the best fire extinguisher will largely be determined by the type of fire that is likely to occur in your business. Here are some additional things that you need to keep in mind.
- Pressure Gauge: Check this often to make sure you are ready to fight a fire at any time. Also make sure you take your rechargeable units to a certified station for recharging.
- Letter Rating: A commercial fire extinguisher will contain a letter rating that tells you the type of fires it can put out.
- Number Rating: The number that precedes the letter and implies the size of fire the extinguisher can put off. Multiply the number before the “A” with 1.25 to get its equivalent in gallons of water.
- Damage: For buildings that have expensive machines such as hospitals and offices, you need to use the water mist extinguishers as they are a lot less likely to cause damage to the machines.
- Durability: Some of the best extinguishers come in a steel casing and equally durable metal valves and levers.
