DIY paint booth fan question

It just takes 1 car...... ask me how I know....isocyanate is no joke!!

I understand but it effects people different. I know a 22 year old girl that had a stroke cause of birth control she was one of those one in a million cases. I'm probably gonna have some future complications cause me and some friends rescued a family from a house that was attached to a car battery recycler that was engulfed in fire i dont even want to know the chemicals we inhaled, worries me from time to time. It's good to know possible side effects. But I'll be painting my car when the time comes.
