Fire Extinguisher/System Regulations Guide
A fire extinguisher system is one of the most critical safety components in motorsport, providing immediate fire suppression in the event of an accident. Whether you’re competing in circuit racing, rally, hill climbs, or endurance events, understanding fire extinguisher regulations is essential to ensure compliance with FIA and Motorsport UK (MSUK) requirements.
According to the National Motorsports Safety Association, all circuit racing cars must be equipped with an On-Board Fire System, with specific requirements for cars registered after January 1, 2009. These requirements include systems certified to SFI specification 17.1 or 17.2, or those listed by the FIA on Technical List No. 16. Details such as the type of extinguishing agent, its capacity, and weight or volume must be visible on the unit. The fire system cylinder must be securely mounted and accessible for inspection and servicing as per manufacturer’s specifications, with a minimum of two nozzle locations for extinguishing agent release.
Why Fire Extinguishers Are Essential in Motorsport
Motorsport vehicles operate under extreme conditions, with high-performance engines, fuel lines, and electrical systems creating an increased fire risk. Having an FIA or MSUK-approved fire extinguisher system significantly improves driver and vehicle safety.
Key Safety Benefits of Fire Extinguishers in Motorsport:
- Immediate Fire Suppression – Prevents fires from spreading and causing severe damage.
- Driver Protection – Quickly contains cockpit and engine fires, reducing injury risks.
- Compliance with Motorsport Regulations – Required for competition entry in most racing events.
- Peace of Mind – Knowing you have a properly installed extinguisher provides confidence on track.
A correctly installed fire extinguisher system can mean the difference between a minor incident and a life-threatening emergency, making it an essential investment for any motorsport vehicle.
Motorsport Fire Extinguisher Regulations
Fire extinguisher regulations vary based on the type of motorsport event, the level of competition, and the governing body (FIA or Motorsport UK).
General Fire Extinguisher Requirements:
- All competition vehicles must have a fire suppression system that meets FIA or MSUK standards.
- Fire extinguishers must be securely mounted in an easily accessible location.
- The system must be maintained and serviced according to manufacturer guidelines.
- Extinguishers must use FIA-homologated suppression agents such as AFFF foam, gas, or powder.
- The activation system must be mechanical (pull-cable) or electrical (push-button).
The table below outlines the specific fire extinguisher requirements for different motorsport event types.
Fire Extinguisher Regulations by Motorsport Event Type
Always check the latest regulations from FIA and Motorsport UK as they may be updated annually.
| Motorsport Event Type | Minimum Fire Extinguisher Requirements | Additional Notes |
| Circuit Racing (FIA & MSUK) | FIA 8865-2015 or FIA 2000-approved system | Minimum 3.0L AFFF foam or 2.0kg gas system |
| Rallying (FIA & MSUK) | FIA 2000 or MSUK-approved system | Minimum 3.0L AFFF foam or 2.25kg gas |
| Hill Climbs & Sprints | MSUK Blue Book-compliant system | AFFF foam system required, minimum 2.25L |
| Endurance Racing | FIA 8865-2015-approved system | Advanced multi-zone fire suppression required |
| Track Days (Non-Competitive) | Not mandatory, but highly recommended | A handheld 2.0L AFFF extinguisher is advisable |
Choosing the Right Fire Extinguisher for Your Motorsport Event
Selecting the correct FIA or MSUK-approved fire extinguisher system is crucial for both compliance and safety. Below are the key factors to consider when making your decision:
Understanding Fire Extinguisher Types
Motorsport fire extinguishers come in two main types, each offering different activation methods and benefits:
- Mechanical Fire Extinguishers (Pull-Cable Activated) – Reliable and simple, manually activated via a pull-cable system, commonly used in rally, club racing, and grassroots motorsport.
- Electrical Fire Extinguishers (Push-Button Activated) – Electronically controlled for instant deployment at the press of a button, typically used in GT racing, endurance events, and high-performance motorsport.
Meeting FIA & MSUK Fire Safety Regulations
To ensure compliance with motorsport regulations, your fire extinguisher system must:
- Be FIA 8865-2015, FIA 2000, or MSUK Blue Book approved, depending on your event.
- Use an AFFF foam or gas-based suppression agent suitable for racing environments.
- Have an approved capacity (e.g., 3.0L AFFF or 2.25kg gas for most racing series).
- Be securely mounted and maintained according to manufacturer guidelines.
Finding the Right Fit for Your Race Car
When choosing a fire extinguisher system, consider:
- Event Type & Regulations – Always check the latest FIA and MSUK requirements before purchasing.
- Suppression Agent – AFFF foam for fuel-based fires, gas-based for clean and instant suppression.
- Weight & Space – Ensure the system fits your vehicle’s cockpit and engine bay requirements.
- Ease of Installation – Choose a system that comes with a complete fitting kit for easy setup.

Mounting and Activation
Extinguishers must be securely mounted with anti-torpedo tabs to prevent detachment in an accident. Both mechanical and electrical activation systems are available, with Motorsport UK recommending electrical triggering systems. However, the best system depends on the specific application.
Servicing
It is crucial to maintain and service fire extinguishers properly. The manufacturer’s servicing schedule should be followed, with servicing required every 24 months at a minimum. For FIA homologated fire extinguishers, they must be serviced by the manufacturer or their agents to maintain their homologation.
Extinguishing Agents
For AFFF (Aqueous Film Forming Foam), a minimum quantity of 2.4 liters is required, while clean agents/gases need to be at least 2.0 kg. It is recommended that the extinguishing agent be directed toward common areas for fire outbreaks, such as the induction, exhaust, ignition, and fuel systems. Adding more nozzles than provided can reduce the effectiveness of the extinguisher due to pressure drop.
Type of Extinguisher
Circuit Racing typically requires a medium plumbed-in extinguisher for discharge into both cockpit and engine bay, with a recommendation for a slimline bottle for single-seaters or sports prototypes.
On-Board Fire Systems
All cars must have an on-board fire system, with specific regulations for cars registered after January 1, 2009. These systems must comply with SFI specification 17.1 or 17.2, or be listed by the FIA on Technical List No. 16. The system should have visible certification labels and details about the extinguishing agent, including type, capacity, and weight or volume.
Safety Mechanisms
All plumbed-in extinguishers must feature a safety mechanism to prevent accidental activation, which must be removed before each track session.
Final Thoughts – Ensuring Motorsport Fire Safety
Fire extinguisher regulations are crucial for driver and vehicle safety in motorsport. Whether you’re competing in circuit racing, rally, endurance events, or hill climbs, ensuring compliance with FIA and MSUK standards is essential.
By choosing the right fire suppression system, you not only meet motorsport requirements but also protect yourself and your vehicle in an emergency. Browse our full range of FIA-approved fire extinguishers to find the perfect system for your race car!
