Can Fire Extinguishers Be Stored Outside

Importance of Outdoor Fire Extinguisher Storage

  1. Enhancing Safety in Open Environments: Outdoor fire extinguisher storage plays a crucial role in enhancing safety in large open spaces such as construction sites, industrial yards, or open-air events. It ensures that fire protection is readily available where fire hazards may be more dispersed or unpredictable.
  2. Accessibility Challenges Indoors: Indoor storage may not always be feasible in certain environments due to limited space or specific operational requirements. In such cases, outdoor storage becomes a practical solution to ensure that fire extinguishers are accessible when needed.
  3. Compliance with Industry Standards: Depending on your location and industry, outdoor fire extinguisher storage may be a regulatory requirement. Compliance with these standards is essential to avoid penalties and, more importantly, to maintain a high level of safety in your facility.

Types of Outdoor Fire Extinguisher Storage

  1. Weatherproof Cabinets: Weatherproof cabinets are specifically designed to shield fire extinguishers from harsh environmental conditions. These cabinets are constructed to be sturdy, durable, and resistant to moisture, UV radiation, and dust, ensuring that extinguishers remain in good condition.
  2. Extinguisher Covers: Extinguisher covers are protective sleeves that can be placed over fire extinguishers. While they may not provide the same level of protection as cabinets, they offer a convenient and cost-effective way to shield extinguishers from light rain, dust, or debris.
  3. Customized Outdoor Storage Solutions: In some cases, custom storage solutions may be necessary. These solutions are tailored to the specific needs of your outdoor environment, ensuring that fire extinguishers remain secure and accessible.

Reasons for Outdoor Storage

  1. Accessibility in Open Areas: The primary reason for outdoor storage is to make fire extinguishers easily accessible in large, open areas. Whether it’s a construction site, a sprawling industrial facility, or an outdoor event venue, outdoor storage ensures that fire protection is never too far away.
  2. Compliance with Local Regulations: In many regions and industries, there are regulations that mandate outdoor fire extinguisher storage in specific situations. Compliance with these regulations is not only a legal requirement but also a prudent safety measure.
  3. Addressing Specific Industry Needs: Some industries, such as forestry, agriculture, or marine operations, have unique outdoor settings where fire risks are prevalent. Outdoor storage is often a necessity in these industries to ensure rapid response to fires.

How to Store Fire Extinguishers Outdoors Correctly

  1. Choosing the Right Location: Selecting the appropriate locations for outdoor fire extinguisher storage is critical. These locations should be strategically placed near potential fire hazards and along evacuation routes for maximum accessibility.
  2. Weatherproof Cabinet Installation: When using weatherproof cabinets, it’s essential to anchor them securely to prevent theft or tampering. Cabinets should be installed at the recommended height for easy access.
  3. Visibility and Signage: Outdoor-stored extinguishers should be highly visible. Proper signage and markings should be used to ensure that their locations are easily identifiable, even from a distance.

Benefits of Outdoor Fire Extinguisher Storage

  1. Immediate Accessibility: Outdoor storage ensures that fire extinguishers are readily accessible in open spaces. This immediate access can be crucial in preventing small fires from becoming large-scale emergencies.
  2. Compliance Advantages: Storing extinguishers outdoors can be a strategic advantage when it comes to regulatory compliance. Meeting outdoor storage requirements demonstrates a commitment to safety and adherence to local standards.
  3. Optimizing Safety in Open Spaces: In open environments where indoor storage is impractical, outdoor storage optimizes safety. It equips personnel with the means to respond to fire incidents swiftly and effectively.


While outdoor storage of fire extinguishers can be practical in specific situations, it’s essential to be aware of its limitations:

  1. Environmental Exposure: Fire extinguishers stored outdoors are exposed to varying weather conditions, such as rain, snow, and extreme temperatures. This exposure can potentially affect their performance and lifespan.
  2. Tampering and Vandalism: Outdoor storage can make fire extinguishers more vulnerable to tampering, vandalism, or misuse. Ensuring their security is a critical concern.
  3. Regular Inspection Demands: Outdoor-stored extinguishers require frequent visual inspections to check for signs of damage, corrosion, or other environmental effects. Monthly checks are essential to maintain their readiness.
  4. Limited Protection: While weatherproof cabinets and covers offer protection, they may not provide the same level of safeguarding as indoor storage. Extensive exposure to harsh conditions can compromise the integrity of extinguishers.


To mitigate the limitations and ensure the effectiveness of outdoor fire extinguisher storage, certain precautions should be taken:

  1. Regular Maintenance: Implement a stringent maintenance schedule that includes monthly visual inspections and professional servicing as recommended by the manufacturer. Regular maintenance is crucial to identifying and addressing any issues promptly.
  2. Security Measures: Utilize security features such as tamper-evident seals, locks, or alarms to deter unauthorized access to outdoor-stored extinguishers. Preventing tampering or vandalism is essential for maintaining their functionality.
  3. Environmental Considerations: Protect fire extinguishers from direct sunlight and extreme weather conditions. Ensure that weatherproof cabinets or covers are in good condition and provide adequate shielding.
  4. Accessibility and Visibility: Place outdoor-stored extinguishers in highly visible locations and clearly mark their positions. Ensuring easy access and quick identification is vital for effective emergency response.
