That’s the other thing, too. It’s rare to be in a situation where you could inhale it. The only example I can think, which is also a rare situation, is if a vehicle that uses it is involved in some kind of accident and breaks the piece of carbon fiber. That could release it into the air causing you to breathe it in.
