TEXT:

This responds to your January 25, 1994, letter asking about how this agency's regulations might apply to your product, the Automated Fire Extinguisher System (AFES). You state that your product's purpose is to allow the operators and occupants of a vehicle to exit safely in the event of a fire. Apparently, the AFES sensors will detect smoke and heat and respond by automatically opening some sort of control valve, whereupon a manifold assembly with "strategically placed directional nozzles" will flood the passenger compartment with some sort of fire extinguisher/retardant. You do not state what kind of fire extinguisher/retardant is used. You explain that the automatic nature of this system will provide time to extract even an unconscious or incapacitated operator or occupant.

Apparently, the AFES has wide applicability. You explain that the AFES proto-type can be installed in a car, truck, boat, RV, or bus or other vehicle running on a 12 volt battery. Apparently you will modify the AFES so that it will run off the 110 volt current in homes and commercial buildings.

I am pleased to have this opportunity to explain our regulations. By way of background information, the National Highway Traffic Safety Administration (NHTSA) is authorized to issue Federal motor vehicle safety standards (FMVSS'S) for new motor vehicles and new items of motor vehicle equipment. Section 102(4) of the National Traffic and Motor Vehicle Safety Act (the "Safety Act") defines, in relevant part, the term "motor vehicle equipment" as:

any system, part, or component of a motor vehicle as originally manufactured or any similar part or component manufactured or sold for replacement or improvement of such system, part, or component OR AS ANY ACCESSORY, or addition to the motor vehicle... (emphasis added).

In determining whether an item of equipment is considered an accessory, NHTSA applies two criteria. The first criterion is whether a substantial portion of the expected use of the item is related to the operation or maintenance of motor vehicles. We determine a product's expected use by considering product advertising, product labeling, and the type of store that retails the product, as well as available information about the actual use of the product. The second criterion is whether the product is intended to be used principally by ordinary users of motor vehicles. If the product satisfies both criteria, then the product is considered to be an "accessory" and thus is subject to the provisions of the Safety Act.

Applying these criteria to the AFES, it appears that this product would be an accessory and thus an item of motor vehicle equipment under the Safety Act. Based on our understanding of the product, it appears that a substantial

portion of the expected use of the AFES system relates to motor vehicle operation. The system is intended to protect anyone occupying a vehicle when a fire occurs. Also, it appears that the product would typically be used by ordinary users of motor vehicles.

While it appears that the AFES system is an item of motor vehicle equipment, NHTSA has not issued any standards for such a device. Nevertheless, there are other Federal laws that indirectly affect the manufacture and sale of your product. You as the product's manufacturer are subject to the requirements in sections 151-159 of the Safety Act concerning the recall and remedy of products with defects related to motor vehicle safety. In the event that the manufacturer or NHTSA determines that the product contains a safety related defect, the manufacturer would be responsible for notifying purchasers of the defective equipment and remedying the problem free of charge.

We have some concerns about the safety impacts if the AFES were to activate while the vehicle is moving. Is it possible, for example, that a driver smoking in the car on a hot day could accidentally set off the sensors, or that they could malfunction spontaneously? Although we do not know what will be coming through the nozzles (fluid, foam, and inert gases are common fire extinguishing agents), we are concerned that AFES activation could cause the driver to lose control in what is otherwise a controllable situation. We urge you to thoroughly consider these and other factors that could affect the safety of motor vehicle operation.

If the AFES were installed by a vehicle manufacturer as original equipment, the vehicle manufacturer would have to certify that the vehicle with the AFES installed complies with all FMVSS's. Among the FMVSS's that might be affected by certain AFES installations are Standard No. 201, "Occupant Protection in Interior Impact," and Standard No. 208, "Occupant Crash Protection."

A commercial business that installs the AFES system would also be subject to provisions of the Safety Act that affect modifications of new or used vehicles. Section 108(a)(2)(A) of the Safety Act (15 U.S.C. 1397(a)(2)(A)) provides that:

No manufacturer, distributor, dealer, or motor vehicle repair business shall knowingly render inoperative, in whole or in part, any device or element of design installed on or in a motor vehicle ... in compliance with an applicable Federal motor vehicle safety standard.

This means that a manufacturer, distributor, dealer, or motor vehicle repair business must not install your device if the system renders inoperative the vehicle's compliance with the FMVSS's. For instance, compliance with Standard No. 208 might be degraded if it were necessary to mount the AFES manifold or directional nozzles in front of the driver or passenger. Any violation of this "render inoperative" prohibition would subject the violator to a potential civil penalty of up to $1,000 for each violation.

Please note also that the render inoperative prohibition does not apply to modifications that vehicle owners make to their own vehicles. Thus, Federal law would not apply in situations where individual vehicle owners install the AFES in their own vehicles, even if the installation were to result in the vehicle no longer complying with the safety standards. However, NHTSA

encourages vehicle owners not to degrade any safety device or system installed in their vehicles. In addition, individual States have the authority to regulate modifications that individual vehicle owners may make to their vehicles, so you might wish to consult State regulations to see whether your device would be permitted.

I hope this information is helpful. I am also enclosing a copy of a fact sheet titled "Information for New Manufacturers of Motor Vehicles and Motor Vehicle Equipment." If you have any further questions about NHTSA's safety standards, please feel free to contact us at this address or by telephone at (202) 366-2992.
