Choosing, Using, and Maintaining Them

Fire extinguishers are a critical first line of defense against workplace fires, but not all extinguishers are created equal. From choosing the right type to ensuring it’s serviced regularly, every workplace should understand how these tools keep people and property safe.

In this guide, we’ll break down the different classes of fire extinguishers, when to use them, and why ongoing maintenance is essential for compliance and safety.

Types of Fire Extinguishers and When to Use Them

Fire extinguishers are categorized by the types of fires they’re designed to combat. Using the wrong extinguisher can be ineffective—or even dangerous—so it’s important to know the difference:

• Class A – Designed for ordinary combustibles like wood, paper, and cloth.

• Class B – For flammable liquids such as gasoline, oil, and grease.

• Class C – Safe for electrical fires involving wiring, appliances, or machinery.

• Class D – Used in industrial settings for combustible metals like magnesium or titanium.

• Class K – Specifically for commercial kitchens, tackling fires caused by cooking oils and fats.

Many workplaces benefit from multi-purpose extinguishers (often labeled A-B-C) that can be used on several types of fires.

How to Use a Fire Extinguisher (The PASS Method)

Even the best extinguisher is useless if staff don’t know how to operate it. The PASS method is a simple and effective way to remember:

• Pull the pin.

• Aim at the base of the fire.

• Squeeze the handle.

• Sweep side to side.

Regular fire safety training ensures employees feel confident and capable in an emergency.

Why Workplaces Must Service Fire Extinguishers Regularly

Having the right extinguisher isn’t enough—it must be properly maintained to work when you need it most. In British Columbia, fire codes require that extinguishers be inspected monthly and serviced annually by a certified professional.

Regular servicing helps:

• Ensure extinguishers are fully charged and operational.

• Detect damage or corrosion that could prevent proper function.

• Keep workplaces compliant with safety regulations and insurance requirements.

Failing to maintain extinguishers could result in fines, liability issues, or catastrophic losses in the event of a fire.
