Which safety guideline should be followed in every science lab to minimize risk?

• A. Always work with a partner during lab activities
• B. Always clean up any broken glass immediately
• C. Always wear a laboratory coat during lab sessions
• D. Always tie back long hair and secure loose clothing

Answer: (D)

Tying back long hair and securing loose clothing is a universal safety habit because it directly reduces the chance of head or body injuries in any lab activity. Long hair or loose fabric can swing into flames, dip into chemicals, or get caught in equipment, causing burns, spills, or entanglement. Keeping hair tied and clothing snug minimizes these risks across all experiments and stations, making it the most consistently applicable safeguard. Other guidelines are important in certain situations, but they aren’t universally required in every lab activity.
