Introduction
It’s easy for building owners to assume they have enough fire extinguishers to meet requirements and protect occupants. However, extinguishers can still be missing from key areas. And even if they’re present, there’s still a chance that the wrong type or size has been installed. That’s why safety audits are so important, as they’re often the moment these deficiencies are first revealed and corrected. This blog will explore how these audits help restore compliance and reduce fire risk.
Why Insufficient Extinguisher Coverage Is Common
Contrary to what many outside the industry may believe, fire extinguisher requirements are not one-size-fits-all. According to NFPA 10, Standard for Portable Fire Extinguishers, they depend on a variety of factors, including hazard type, building layout, occupancy, and floor area.
Given the previously mentioned requirements, it can be hard to understand how deficiencies arise in the first place. ToolGrit cites these reasons to be:
- Extinguishers are undersized or spaced too far apart.
- Buildings are renovated or expanded without updating coverage.
- New hazards (commercial kitchens, flammable liquids, and electrical areas) are added.
- Type: Whether extinguishers match the fire classes present
- Quantity: Whether enough extinguishers exist for the total hazard area
- Size and Rating: Whether extinguisher ratings meet minimum requirements
- Placement: Whether units are within NFPA‑mandated travel distances and properly mounted
- Accessibility and Visibility: Whether extinguishers are unobstructed and clearly identifiable
While this may sound concerning, this is exactly why safety audits exist.
What a Fire Extinguisher Safety Audit Reviews
As defined by Green World Group, “a fire safety audit is a systematic process of evaluating a building, facility, or organization to determine its level of preparedness and compliance with fire safety regulations. It identifies potential hazards, assesses the effectiveness of safety measures, and helps to create a safer working environment.”
When it comes to fire extinguishers specifically, US Made Supply says that audits typically confirm:
This is often completed at least once per year, as required by an authority having jurisdiction (AHJ), insurance company, or internal policy. Based on the audit results, businesses may receive citations. More information on the cost of neglecting fire safety is available here.
How Codes Define “Enough” Fire Extinguishers
Before the audit, building owners need to prepare and put their best foot forward. One way to do this is to become aware of what counts as “enough” fire extinguishers. The answer isn’t so cut-and-dry, but NFPA offers guidance on how to decide based on each building’s hazard level and floor area.


(NFPA, Fire Extinguisher Placement Guide)
For example, a large light-hazard area may need a fair number of 4A‑rated extinguishers, spaced to ensure no one has to travel more than the required distance to reach one. NFPA isn’t the only one with such requirements. Occupational Safety and Health Administration (OSHA) 29 CFR 1910.157 reinforces the importance of extinguishers, stating that when provided, they must be readily accessible, maintained in operable condition, and properly selected for the hazards present.
Yes, OSHA allows for total evacuation policies in limited cases, such as intense heat or a hazardous atmosphere. But it’s still recommended that, in most commercial occupancies, extinguishers be treated as the first line of defense. This, of course, makes both quantity and placement essential. Even with all this out in the open, buildings can still fall short.
Correcting the Deficiencies
As a technician, it’s always good to know common fire extinguisher deficiencies and, more importantly, how to correct them. NFPA lists some common solutions, such as:
- Relocating extinguishers to improve visibility.
- Adding extinguishers to meet the NFPA 10 travel distance.
- Ensuring mounting heights and signage meet code requirements.
- Upgrading to higher‑rated extinguishers in areas of increased hazard levels.
Taking measures like the ones above is about more than resolving individual issues. It creates consistency, simplifies documentation, and reduces risk. This is especially for those managing multiple facilities.
