Any scientific laboratory work poses potential hazards. These are minimized by use of safe laboratory procedures and apparatus, and by exercising ordinary common sense. Both instruments and chemical reagents can pose safety hazards if used improperly or carelessly. Ordinary eyeglasses are NOT sufficient.
Contact lenses are particularly dangerous.
If you do get anything in your eye, contact lenses can make it very difficult to expel or wash out the foreign matter. Shoes must be worn. Sandals or open-toed shoes are unacceptable. Your clothing must cover the trunk of your body and your shoulders. If you wear shorts or a short skirt, also wear a lab coat or apron.
