In September 1999 a UW student, in a research lab, completed one step in a process, pulled the fume hood sash down, stepped away from the hood, took off his safety glasses, and caught a shard of glass in the eye from an explosion in the hood. This month, a UW student, in a research lab, was not using eye protection and received a chemical splash in the eye. Statisticians tell us that a percentage of the people reading about these accidents will not believe that it could happen to them. If you do not use the correct PPE all of the time, it won't do you any good. And there may be a severe price to pay to find that out.
Most people have experience wearing gloves to protect their hands.
You probably do too. Maybe you wore them while you were working in your lab or while you changed the oil in your car or last night when you washed the dishes. You made some decisions when you wore those gloves. You know oven mitts aren't good for changing oil, and leather work gloves wouldn't have been too helpful when you did the dishes. Nitrile gloves work for the former, butyl gloves for the latter.
