Have you noticed your fire extinguisher pressure gauge slowly dropping?

A fire extinguisher can lose pressure for several reasons:

• Aging seals
• Valve leaks
• Accidental discharge
• Physical damage
• Extreme temperatures

The good news is that many units can be serviced if the issue is caught early.

We put together a guide explaining the most common causes of pressure loss and what steps you should take next.

Got old or expired fire extinguishers sitting around?

ABC and CO₂ extinguishers shouldn’t be thrown in regular garbage because they’re still pressurized and may contain chemical agents.

At Rapid CO₂ in Ottawa, we safely:
• Depressurize extinguishers
• Recycle metal components
• Repurpose certain units for training or parts

Fire extinguisher disposal is available for $8.50 per unit and units can be dropped off directly at our facility.

You’ll need:
• CO₂ tank (hydro tested every 5 years)
• CGA320 to TR21-4 refill adapter
• Scale for safe filling

We break down the full setup here.

We also provide CO₂ refills and hydro testing in Ottawa.

Not all CO₂ cylinder testing methods are the same. When it comes to requalifying CO₂ cylinders—especially for fire extinguishers or compressed gas use—understanding the difference between water jacket testing, proof pressure testing, and ultrasonic examination helps you choose the proper method for safety and compliance. Water jacket testing measures volumetric expansion under pressure, proof pressure checks for visible leaks or deformation using simpler equipment, and ultrasonic testing scans the cylinder wall without pressurizing it.

In Canada, most commercial CO₂ fire extinguishers require water jacket testing, and ultrasonic options may apply for certain aluminum or specialized cylinders.
