How should long hair be managed in the lab?

• A. Tie back if hair is longer than 8 inches
• B. Keep hair down
• C. Hair color change required
• D. Hair must be shaved

Answer: (A)

Long hair must be secured in the lab because loose hair can ignite from flames, drip into chemicals, or get caught in moving equipment, leading to burns, contamination, or mechanical injuries. When hair is longer than about eight inches, tying it back keeps it away from your face and heat sources, reduces the chance of splashes reaching the hair, and helps you work safely with both hands free and your vision unhindered. Keeping hair down increases exposure to heat and chemicals, which is unsafe. Hair color change or shaving aren’t typical safety requirements for managing hair in the lab.
