I totally agree with every thing said exhaust extraction, doors open and face masks..

But at the end of the the day it comes down to education and time..

How many of you when you were 16 left school and indestructible where told by some old fart not to lie on the cold concrete floor or you will get something or the other or put a face mask on because someone going to respray a car in the workshop??
Bet you wish you took notice now....
