Long hair and loose clothing that can get caught in glassware or pose a danger in the laboratory should be withdrawn.
Wear proper clothing when working in the laboratory. Long hair, hanging jewels, loose clothing, and baggy clothing are dangerous in the laboratory. Long hair should be tied at the back.
