May have said this before but bears repeating, Drivers if you wear dentures or partials remove them b4 racing, may choke on them in a crash. Deodorant should be used AFTER the races, the human body sweats to cool itself off. & PLEASE use it on the way home, other riding w/ you will appreciate it. All metal of any kind should be removed, if it gets hot it will stay hot longer & cause a nasty burn. If it's a medical alert tag put the info on your helmet, EMERGENCY CREWS take note if driver is breathing ok leave the helmet on. Especially if driver is unconscious, unless you need to remove it for some other reason. But take it to the hospital if driver goes, Docs at hospital will like to see where the hit was. T-SHIRTS UNDER THE FIRESUIT this is a pet peeve of mine. A soaking wet t-shirt will get you burned quick, it's like boiling water. Firesuits stop the fire, they stop the heat but not forever. The fireproof underwear is a lot better, it compliments the suit & adds time. Do you race at a 1/4 mile w/ walls or a 1/2 mile w/ no walls. How long will it take the rescue people to get to me. If they don't have one or an ambulance LEAVE, it's your life how long do want to live it. You AHHH won't happen to me, got news for you - theirs a million others saying the same thing. It's gonna happen to somebody gang be smart be safe
