Fire safety is a fundamental aspect of any residential, commercial, or industrial setting. Fire extinguishers are your first line of defence when dealing with small fires, but their effectiveness depends entirely on their condition. That’s why fire extinguisher maintenance and routine fire extinguisher inspection are so vital. Whether you have portable fire extinguishers, wheeled fire extinguishers, or wall-mounted units, regular checks, including pressure testing, are critical to ensuring the extinguisher will operate correctly in an emergency.
Why Pressure Testing Fire Extinguishers Matters
Pressure testing of fire extinguishers, also known as hydrostatic testing, is a critical process that checks whether the extinguisher cylinder can safely hold pressure. Over time, fire extinguishers may develop internal wear, corrosion, or even unseen damage that could compromise their performance. If a fire extinguisher fails during an emergency, the results can be disastrous. Proper testing ensures the extinguisher is fully functional and ready to save lives when needed. This is particularly crucial in areas prone to electrical fires, grease fires, or gas fires.
Inspection vs. Testing: What’s the Difference?
A fire extinguisher inspection typically involves a thorough inspection of the unit’s components — checking the pressure gauge, tamper seal, locking pin, hose, and general condition. It’s a visual and manual check done at regular intervals, often monthly.
Pressure testing, on the other hand, is a more advanced process. It involves completely emptying the extinguisher, filling it with water, and pressurising it to a level above its normal operating pressure to confirm structural integrity. This test must be carried out by experienced technicians using specialised equipment and must follow Australian Standards.
Australian Standards for Fire Extinguisher Testing
In Australia, AS 1851 outlines the testing requirements for fire protection equipment, including fire extinguishers, hose reels, and wet chemical systems. According to this standard:
- Most portable fire extinguishers must be hydrostatically tested every 5 years.
- CO2 extinguishers require testing every 10 years.
- Regular inspections (monthly/6-monthly) must also be carried out to check accessibility, condition, and pressure levels.
Failure to follow these regulations and adhere can lead to non-compliance issues and, worse, fire hazards.
Types of Fire Extinguishers & Their Testing Needs
Different extinguishers require different care and testing intervals:
- Water and Foam Extinguishers: Ideal for Class A fires (combustibles like paper and wood). Must be inspected and pressure tested every 5 years.
- Carbon Dioxide Extinguishers: Used for electrical fires and Class E fires. Require a hydrostatic test every 10 years.
- Wet Chemical Extinguishers: Best for cooking oil and grease fires. Require standard pressure testing every 5 years.
- Dry Chemical Extinguishers: Effective on multiple fire types. Inspection and hydro testing are required at prescribed intervals.
Ensuring each extinguisher is tested according to its testing requirements is vital for fire safety compliance.
Fire Extinguisher Maintenance Essentials
Fire extinguisher maintenance includes:
- Checking the pressure gauge to ensure correct operating levels
- Inspecting for corrosion, damage, or missing components
- Ensuring equipment is easily accessible and not blocked
- Replacing expired or damaged extinguishers
- Scheduling regular refill services
A unit that looks fine to an untrained eye may still be unsafe. That’s why inspections and pressure testing must be carried out by a fire safety professional.
Extinguisher Pressure Testing Procedures Explained
- Inspection: The extinguisher is checked for obvious damage or wear.
- Discharge: Any remaining extinguishing agent is safely released.
- Cylinder Filling: The cylinder is filled with water.
- Pressurisation: The extinguisher is pressurised to a specific PSI as outlined in the standards.
- Evaluation: Technicians monitor the unit for leaks, pressure loss, or corrosion.
- Drying & Reassembly: If it passes, the extinguisher is dried, reassembled, and refilled.
This process ensures the unit is in working order and structurally sound to handle emergencies.
Common Problems Found During Testing
Testing can reveal:
- Corrosion inside or outside the cylinder
- Damaged or missing locking pins, tamper seals, or hoses
- Failing pressure gauges
- Extinguishers past their testing dates
- Units not suitable for the building’s current fire risk profile
Any extinguisher that fails must be replaced or repaired immediately.

Frequently Asked Questions
How are fire extinguishers pressure tested?
Fire extinguishers are hydrostatically tested — filled with water and pressurised to check for leaks or structural failure. This process ensures the cylinder can safely contain its extinguishing agent under pressure.
How often should fire extinguishers be pressure tested?
According to Australian Standards, most portable fire extinguishers should be professionally hydrostatically tested every 5 years. Carbon dioxide extinguishers require testing every 10 years.
How do you check the pressure of a fire extinguisher?
Look at the pressure gauge on the extinguisher. The needle should be in the green zone. If it’s low or high, the unit may require servicing or fire extinguisher maintenance.
What is the Australian standard for fire extinguisher testing?
AS 1851 is the relevant standard. It outlines the testing intervals, procedures, and inspection protocols to keep fire extinguishers in optimal condition and ready for emergencies.
