Fire extinguishers are an essential component of any fire safety plan, and regular inspections ensure they’re functional and compliant. In New Zealand, these fire extinguisher inspections are necessary for businesses with fire extinguishers on site, as they help maintain compliance with the NZS 4503:2005 standard, which governs the care and maintenance of firefighting equipment. However, many businesses inadvertently fail their fire extinguisher inspections due to easily avoidable issues.

This article outlines the most common causes of inspection failures in New Zealand, including expired extinguishers, improper placement, insufficient pressure, and more. By understanding these pitfalls, you can take proactive steps to ensure that your fire extinguishers are always inspection-ready and fully operational in case of an emergency.

1. Expired Fire Extinguishers

One of the most common reasons for failing a fire extinguisher inspection is having an extinguisher that has expired. Every fire extinguisher has a lifespan, which is typically marked on the body of the unit. Over time, the chemicals inside can degrade, and the extinguisher may lose pressure, making it ineffective in a fire emergency.

How to Avoid This Issue

  • Check Expiry Dates Regularly – Make a habit of inspecting the expiry date on each fire extinguisher.
  • Replace When Needed – If an extinguisher is near its expiry date, consider replacing it promptly to avoid inspection failure.

2. Insufficient Pressure

Fire extinguishers rely on a certain level of pressure to discharge their contents effectively. An extinguisher with low or insufficient pressure is likely to fail during an emergency and will also fail a fire extinguisher inspection. Pressure levels can drop due to leaks, corrosion, or gradual pressure loss over time.

How to Avoid This Issue

  • Regularly Check Pressure Gauges – Fire extinguishers have a pressure gauge, which should indicate whether the unit is within the correct pressure range.
  • Engage a Qualified Technician – A professional inspection service can test pressure levels and recharge extinguishers as needed.

3. Improper Placement and Accessibility

Fire extinguishers should be strategically placed for easy access in an emergency. If an extinguisher is blocked, stored in a hard-to-reach area, or not mounted at the proper height, it could lead to inspection failure. Improper placement can also increase the risk of someone being unable to access it quickly during a fire.

How to Avoid This Issue

  • Ensure Clear Access – Make sure fire extinguishers are not obstructed by furniture, stock, or other objects.
  • Follow Placement Guidelines – Position extinguishers where they are visible and accessible, as recommended by fire safety standards.

4. Incorrect Type of Fire Extinguisher

Fire extinguishers are designed for specific types of fires. For example, a water extinguisher is unsuitable for electrical fires, while a CO2 extinguisher is better suited for fires involving electrical equipment. Having the incorrect type of extinguisher for your environment or potential fire risks is a common cause of inspection failure.

How to Avoid This Issue

  • Conduct a Fire Risk Assessment – Assess the types of fire hazards in your business to determine which extinguishers are required.
  • Consult a Fire Safety Professional – If you’re unsure, a fire safety expert can recommend the right extinguishers for each area.

5. Physical Damage

Fire extinguishers are built to be durable, but physical damage can render them ineffective. Dents, cracks, and rust are common causes of fire extinguisher failure. An extinguisher that appears damaged will likely fail a fire extinguisher inspection, as it may not function properly in an emergency.

How to Avoid This Issue

  • Inspect Extinguishers for Visible Damage – Regularly check each extinguisher for signs of dents, cracks, or rust.
  • Repair or Replace Damaged Units – If an extinguisher is damaged, it’s best to replace it immediately to maintain compliance and safety.

6. Missing or Damaged Safety Seals and Pins

The safety pin and seal on a fire extinguisher ensure that it hasn’t been tampered with or accidentally discharged. If these are missing, damaged, or broken, it can indicate that the extinguisher may not be fully functional or may have been partially used. Fire extinguisher inspections will fail if the seal or pin is compromised.

How to Avoid This Issue

  • Regularly Check Pins and Seals – Make sure that each extinguisher has an intact safety pin and seal.
  • Replace Seals After Testing – If an extinguisher has been tested or inspected, ensure a new safety seal is applied to indicate it is ready for use.

7. Lack of Regular Maintenance Records

For businesses in New Zealand, maintaining accurate records of fire extinguisher inspections and maintenance is crucial. Failure to provide maintenance records during an inspection can result in a failed inspection. These records are also necessary for ensuring compliance with NZS 4503:2005.

How to Avoid This Issue

  • Keep Detailed Records – Document each inspection, including the date, findings, and any maintenance performed.
  • Use a Professional Service – Engaging a qualified service provider can help ensure your records are up-to-date and accessible for future inspections.

8. Obstructed or Hidden Extinguishers

In some cases, fire extinguishers are hidden behind furniture, merchandise, or other items, which can prevent easy access during an emergency. An obstructed extinguisher can lead to inspection failure because it is not easily accessible.

How to Avoid This Issue

  • Conduct Regular Visibility Checks – Make sure that fire extinguishers are always visible and unobstructed.
  • Educate Staff on Fire Extinguisher Placement – Ensure that employees understand the importance of keeping fire extinguishers accessible at all times.

9. Outdated or Missing Signage

Fire extinguishers need to be clearly marked with signage that indicates their location and type. Missing or outdated signage can lead to confusion during an emergency and may result in an inspection failure.

How to Avoid This Issue

  • Regularly Check Signage – Make sure all fire extinguisher signs are visible and up-to-date.
  • Replace Worn or Faded Signs – If signs are faded or damaged, replace them promptly to maintain compliance.

10. Incorrect Mounting Height or Location

Fire extinguishers should be mounted at a height that allows for quick access without obstruction. Placing an extinguisher too high, too low, or in an incorrect location can lead to an inspection failure.

How to Avoid This Issue

  • Follow Mounting Guidelines – Position fire extinguishers at the recommended height and ensure they are accessible.
  • Conduct Routine Checks – Regularly verify that extinguishers remain in the correct location and are easily reachable.

11. Missing Inspection Tag

An inspection tag is typically attached to each fire extinguisher to record its last inspection date. If this tag is missing, damaged, or not updated, it could result in an inspection failure.

How to Avoid This Issue

  • Ensure Tags are Attached and Visible – Each extinguisher should have an inspection tag that is current and legible.
  • Update Tags During Each Inspection – After each inspection, ensure the tag is marked with the new date and any notes as needed.

12. Lack of Staff Training on Fire Extinguisher Use

While staff training may not directly cause an inspection failure, it’s a vital aspect of maintaining a safe environment. Employees who are not trained on proper fire extinguisher use may inadvertently damage or misuse extinguishers, leading to potential issues down the line.

How to Avoid This Issue

  • Provide Fire Extinguisher Training – Regularly train staff on fire extinguisher use and handling.
  • Encourage Awareness – Make sure employees understand the importance of keeping extinguishers in good condition and accessible.

13. Unclear Labels or Instructions

Fire extinguishers come with labels that specify their type and instructions for use. If these labels are worn, damaged, or unclear, it can result in inspection failure because users may not be able to quickly understand how to operate the extinguisher.

How to Avoid This Issue

  • Regularly Inspect Labels – Check that each extinguisher has a clear and legible label.
  • Replace Faded or Damaged Labels – Ensure labels are in good condition to avoid any confusion in an emergency.
