but full-on flames – like the ones that engulfed both martin truex jr.’s and kyle larson’s cars sunday during the brickyard 400 – are a different story. as fox sports analyst larry mcreynolds and driver aj allmendinger explained while recapping the indianapolis motor speedway race, each car is required to have two fire suppression systems on board. these combined to quickly turn truex’s flaming car into a ball of smoke as he climbed out onto the track.
@larrymac28 and @ajdinger look into one of sunday’s biggest moments. one is for the cockpit, and it’s driver-activated. one is for the rear of the car in the trunk above the fuel cell, and it’s heat-activated. it can work off of either one of those systems right there, and it’s normally located right on the fire wall right there behind the engine.
note the positioning of both push buttons to activate the system in the image at top left, as well as the placement of the fire bottle in the image at bottom left. when choosing a fire suppression system, all of our experts agreed that the first resource to turn to is the sanctioning body or series rulebook. an oil line or even a power steering line, on the cars that still have it, is more likely to come off and catch fire compared to a fuel cell having a puncture or a leak and creating a fire.” series not affiliated with either fia or sfi, such as the scca, nasa, and club race events, “will allow either sort of system,” schucker said, “as long as you follow the manufacturer’s guide to installation and that you’re up to certification on that system.” stroud safety has an easy-to-understand diagram in its suppression system installation instructions showing the recommended locations for the fire bottles and how they should be oriented.
mounting the bottle low in the chassis, parallel to the ground but perpendicular to the chassis axis, is stroud safety’s preferred location; the next best is mounting the bottle parallel to the ground and in line with the chassis axis, with the bottle head pointing to the rear of the vehicle. “make sure you can still reach it quickly and efficiently when you’re harnessed in, in the helmet and neck brace.” also check that the pull handle “is firmly mounted,” said cunningham, or you won’t be able to “fully open the system.” it takes a firm pull to activate the system. “that has to be one of the things on your pre-race checklist.” another item for the pre-race checklist is bottle recertification and refilling, schucker said. so you’re either stuck with ground shipping the bottle to and from, or if you’re in a rush, you may have to find someone to physically drive the bottle somewhere.” bottles must be sent to a company “certified for that style of system,” he added.
however, cars being able to put out their own fires is one of nascar’s many safety enhancements developed over the years. nascar on nbc. today’s race car fire suppression systems use a chemical called dupont fe-36. it was developed specifically for motorsports. it is sfi approved, does not scca requires sfi- or fia-approved fire suppression systems in all new racecars. we carry sfi-approved fe-36 and fia-approved afff or novec fire systems., drag racing fire suppression systems, drag racing fire suppression systems, phoenix fire systems race car, race car fire suppression system, race car fire suppression system installation.
nascar requires a 5-lb manually-activated fire extinguisher in the driver’s compartment. the drawing below shows the locations of the nozzle and the switch. in 2003, nascar required a separate, thermally activated fire extinguisher system for the fuel-cell area. firebottle safety systems – fire bottle fire suppression system – 5 lb fire bottle spare aluminum bottle – 5lb – dupont fe36 (nascar. following these basic yet critical components of using and installing a fire suppression system can lead to a protected race car, summit racing carries manual, electric and automatic race car fire suppression systems that are dry chemical and clean agent, dirt car fire suppression system, nhra fire suppression system, 10lb fire suppression system, sfi fire suppression system, sprint car fire suppression system, safecraft fire suppression, nhra fire suppression system rules, fire bottle fire suppression system, stroud fire suppression system, firefox fire suppression.
