In the chemistry lab, what should you do with long hair and jewelry?

• A. Tie long hair back and remove jewelry
• B. Leave hair loose and wear jewelry
• C. Tie hair back but keep jewelry
• D. Wear more jewelry to protect yourself

Answer: (A)

The main safety idea is to keep anything that could catch fire, snag on equipment, or become contaminated away from your face and the work area. Long hair can easily brush into an open flame or hot surface and can snag on glassware or stirring rods, leading to burns or spills. Jewelry can trap chemicals, get caught in moving parts or glassware, or heat up if it comes near heat sources, increasing injury risk. For these reasons, tying back long hair and removing jewelry minimizes these hazards and is the safest practice in the chemistry lab.
