It would not take a genius to deduce that motorsport is pretty dangerous. So it isn’t surprising that in NASCAR, the crew chiefs sometimes wear fire suits. Most of the time, they wear regular clothes at the track, especially when they are in the pit box. However, there are occasions where the crew chief gets personally involved in the car’s mechanics.

Additionally, the pit box is situated close to the pit stall. This means that there is a potential risk of a large pit fire. Owing to this, it is far more practical for crew chiefs to wear fire suits for the sake of safety. It is also worth mentioning that this rule was enforced in 2002. Furthermore, it was the first year that any pit crew member going over the wall had to wear a fire suit.

Why is it so important for NASCAR crew chiefs to wear fire suits?

Back in 2007, Simpson Performance Products operations manager Dave Nelson, spoke about the suits. He said, “Our No. 1 goal has always been driver safety. That’s never changed. Nomex, a flame-resistant fiber made by DuPont, has been around for 40 years, and that’s what we use to make the suits. But the performance of our fabrics has changed, and even the function of the suits has changed.”

Aside from the crew chief, the same rules apply for over-the-wall pit crew members. As per reports, these uniforms need to have an SFI rating of 3.2A/1, a TPP value of six, and a protection time of 3 seconds. However, Nelson admitted that the above standards were just the minimum requirement.

At the end of the day, NASCAR is concerned with the drivers’ comfort and safety. He also said that while there is a minimum standard, the aim is to be above it. However, there is also the drivers’ size and weight to consider when the suit is decorated. Unfortunately, sponsor logos and other bits have a tendency to add weight.
