Yeah i thought that was quite a weird question...
i put that enzymes are irritants and also it said in the passage about forming air born dust so i wrote wearing breathing masks. Also it said about blisters on the skin so i talked about wearing gloves, lab coat and eye protection ie googles. I also put an alternative and said to minimize overall contact with it the experiment could be carried out in a fume cupboard.
I'm really not sure if mine was correct but thats what i wrote.. what about you?
