Everything You Need to Know About Fire Extinguisher Inspections
Fire extinguishers are an important part of a building’s fire protection system, but simply having them on site does not mean they are ready to use in an emergency. Over time, an extinguisher can become damaged, lose pressure, become obstructed, or be moved from its designated location. Regular inspections help identify these issues before the equipment is needed.
Fire extinguisher inspections involve checking the extinguisher’s condition, accessibility, location, pressure and other factors that can affect its performance. Businesses and property owners also need to keep up with applicable inspection, maintenance and testing requirements to ensure their fire extinguishers remain in serviceable condition.
This guide explains what fire extinguisher inspections involve, how often they should be carried out, what inspectors check, and how inspections differ from maintenance and testing.
Why Fire Extinguisher Inspections Are Important
Regular fire extinguisher inspections help confirm that extinguishers remain accessible, properly positioned and ready for use. Issues such as low pressure, physical damage or blocked access can affect an extinguisher when it is needed most.
Protecting People and Property
A fire extinguisher can help control a small fire before it spreads. Regular inspections help identify problems that could prevent an extinguisher from being used effectively during an emergency.
Making Sure Extinguishers Are Ready to Use
An extinguisher may look fine on the outside but still require attention. Inspections check its condition, pressure, accessibility and other factors that can affect its readiness.
Reducing Business and Compliance Risks
Businesses need to maintain their fire protection equipment and meet applicable fire safety requirements. Keeping up with inspections and addressing problems promptly can help reduce operational and compliance risks.
How to Properly Inspect a Fire Extinguisher
A basic visual inspection can help identify visible problems with a fire extinguisher. Regular checks should be combined with the required professional inspection, maintenance and testing to keep the equipment in suitable working condition.
Conduct a Visual Inspection
- Confirm that the extinguisher is in its designated location and easy to access.
- Check for dents, corrosion, leaks or other visible damage.
- Make sure the safety pin and tamper seal are intact.
- Check the pressure gauge, where provided, and confirm that the indicator is in the appropriate range.
- Make sure the operating instructions and extinguisher label are legible.
Verify Inspection Tags and Maintenance Records
- Check the inspection tag for the latest inspection information.
- Review maintenance records to confirm that required service has been completed.
- Keep records organised for each extinguisher on the property.
- Follow the applicable schedule for inspection, maintenance and testing.
Identify Issues That Require Professional Service
- Look for signs of corrosion, physical damage or pressure loss.
- Arrange professional service if the extinguisher has been discharged or appears damaged.
- Do not attempt to repair, recharge or modify a fire extinguisher yourself.
- Remove an extinguisher from service when required and follow proper replacement or servicing procedures.
Schedule a Professional Fire Extinguisher Inspection
- Arrange inspections with a qualified fire protection professional.
- Have each extinguisher assessed according to applicable requirements.
- Address any maintenance or repair issues identified during the inspection.
- Keep documentation of completed inspections and service.
Types of Fire Extinguishers
Different fire extinguishers are designed to handle different types of fires. Choosing the right extinguisher depends on the materials that may catch fire and the environment where the extinguisher is installed. Regular inspections are also important to ensure each extinguisher remains in suitable working condition.
Water Extinguishers
Water extinguishers are generally used for Class A fires involving materials such as wood, paper and textiles. They should not be used on fires involving flammable liquids or live electrical equipment.
Foam Extinguishers
Foam extinguishers can be used on certain Class A and Class B fires. They are commonly suitable for fires involving materials such as wood and paper, as well as some flammable liquids. Their suitability depends on the specific extinguisher and fire risk.
Dry Powder Extinguishers
Dry powder extinguishers are available for use on several types of fire, depending on the powder formulation. They can be suitable for certain flammable liquid and gas fires, and some types can also be used around electrical equipment.
Carbon Dioxide (CO2) Extinguishers
CO2 extinguishers are commonly used for fires involving electrical equipment and certain flammable liquids. They discharge carbon dioxide and do not leave the same type of powder or foam residue associated with other extinguishing agents.
Wet Chemical Extinguishers
Wet chemical extinguishers are primarily designed for cooking oil and fat fires, making them particularly relevant to commercial kitchens. They are formulated to help control high-temperature cooking fires and reduce the risk of re-ignition.

How Often Do Fire Extinguishers Need to Be Inspected?
Fire extinguisher inspection and maintenance schedules depend on the type of equipment, its location and applicable fire safety requirements. A routine visual check does not replace the more detailed maintenance and servicing that may be required.
Monthly Visual Inspection
Fire extinguishers should receive regular visual inspections to identify obvious issues. The inspection should check that the extinguisher is in its designated location, accessible, properly identified and free from visible damage. The pressure indicator, where provided, should also be checked.
Annual Maintenance
Fire extinguishers generally require maintenance at least once a year. This service involves a more detailed examination than a routine visual inspection and can identify problems that may not be apparent during a basic check. Required maintenance should be performed by a qualified fire protection professional.
Internal Fire Extinguisher Maintenance
Some extinguishers require periodic internal examination and maintenance in addition to routine inspections. The timing depends on the extinguisher type, applicable requirements and manufacturer instructions. Internal maintenance can involve examining the cylinder and components, servicing the extinguishing agent and replacing parts when necessary. A qualified technician should perform this work.
What Does a Professional Fire Extinguisher Inspection Include?
A professional fire extinguisher inspection involves more than checking whether an extinguisher is present and accessible. A qualified technician examines the equipment, checks for conditions that could affect its performance and identifies any maintenance or corrective work that may be needed.
Comprehensive Visual Inspection
The technician examines each extinguisher for visible signs of damage, corrosion, leakage, tampering or other conditions that could affect its serviceability. The extinguisher’s location, accessibility, identification and overall condition are also checked.
Performance and Safety Checks
The inspection includes checks of components and indicators that can affect safe operation. Depending on the extinguisher type, this may include the pressure gauge, safety pin, tamper seal, hose, nozzle and other operating components.
Code Compliance and Documentation
The technician checks whether the extinguisher is being inspected and maintained according to applicable fire safety requirements. Inspection and maintenance information should be properly documented so property owners can keep accurate service records.
Maintenance Recommendations and Corrective Actions
If an extinguisher requires maintenance, repair or replacement, the technician can identify the issue and recommend the appropriate action. Problems found during an inspection should be addressed promptly rather than leaving an extinguisher in service when it may not perform as intended.
