Question: A heavy-duty equipment technician is using a pneumatic impact wrench to remove lug nuts from a large truck tire. The technician has selected the correct socket and confirmed the air pressure. What specific safety practice should the technician also adhere to when operating this power tool?

Answer options:

• Use both hands to steady the wrench and apply even pressure to avoid kickback.
• Keep fingers clear of the trigger until ready to operate to prevent accidental activation.
• Ensure the air hose is routed away from walkways to prevent tripping hazards. ✅ Wear appropriate eye and hearing protection, and ensure the tool is properly lubricated.

Correct answer: Wear appropriate eye and hearing protection, and ensure the tool is properly lubricated.

Explanation: Pneumatic impact wrenches generate significant noise and can cause metal fragments or debris to fly. Therefore, eye protection (safety glasses or goggles) is crucial to protect against flying debris, and hearing protection (earplugs or earmuffs) is essential to prevent noise-induced hearing loss. Proper tool lubrication is also part of safe operation and maintenance.
