Which of the following is a general safety principle around rotating equipment?

• A. Do not wear loose clothing or jewelry; keep hair secured
• B. Wear sandals for grip
• C. Stand in direct contact with moving parts
• D. Remove all PPE after startup

Answer: (A)

Preventing entanglement around rotating equipment is the key idea. Loose clothing, jewelry, and long hair can be grabbed by belts, pulleys, gears, or rotating shafts, pulling you into the machine or causing serious injury. Keeping hair secured and removing loose items is the safest general principle because it directly reduces the risk of being caught in moving parts. Other practices would not provide the same protection: sandals do not offer adequate foot protection and can slip; standing in direct contact with moving parts is dangerous and should be avoided; PPE should remain in place during operation to continue providing protection rather than being removed.
