Which item is explicitly listed as requiring guards?

• A. Saw blades
• B. Hood ornament
• C. Bottle cap
• D. Door handle

Answer: (A)

Guarding moving parts is about preventing contact with parts that can injure you during operation. Saw blades are explicitly required to have guards because they rotate at high speed and have sharp edges, creating a severe risk of lacerations or amputations if a hand or tool comes into contact with them. A guard acts as a protective barrier, reducing the chance of accidental contact and kickback. The other items don’t involve exposed rotating components that are mandated to be guarded in typical mining machinery. Hood ornaments and door handles aren’t moving parts that pose the same direct cutting hazard, and a bottle cap doesn’t represent a dangerous machine component requiring guarding.
