I am the person who violates most rules (the machine manual suggests we wait 1 min to increase 1 step, i guess the engineer included a safety factor of 2 so i can safely do 40sec on busy day(i have to do this a lot so 20 sec saving once is like 20 mins a hour), you need to wear proper ppe, but i am in hurry, and have to remove it before doing other work, might as well wear half of it, and insure i do not use other half(this one is not that bad cause i am not handling something toxic, it’s just that i may contaminate some stuff, and this thing does not really require full clean room treatment)
