Protect
your eyes against possible breaking glass, chemicals, etc. by wearing
safety glasses. Wear close-fitting clothes so that they don't catch on
things and knock them over (sleeves, etc) or catch on fire. Tie your
hair back so that it doesn't catch on fire or fall into chemical
solutions. Natural fibers tend to be more flammable than man-made.
Consider what would happen if you shake a test tube that has chemicals
in it. Consider what could happen if you look into a test tube where a
chemical reaction is taking place. Consider what could happen if
chemicals spill from the test tube while you are holding it.
Hope it helped : )
