When using power tools, what two precautions are most important?

• A. Wear gloves and keep the area tidy
• B. Use eye protection; ensure proper grounding
• C. Use loud music to stay focused
• D. Shut off power after use only

Answer: (B)

Eye safety and electrical safety are the priorities when operating power tools. Eye protection is essential because power tools can eject metal chips, wood fragments, dust, or sparks that can injure your eyes in an instant. Safety glasses or a face shield create a barrier that helps prevent serious eye injuries during cutting, grinding, or drilling. Proper grounding is a fundamental part of electrical safety. It gives any fault current a safe path to the ground, which helps prevent electric shock if the tool’s insulation fails or a live wire is nicked. Grounding also works with protective devices like fuses or circuit breakers to shut the circuit off quickly if something goes wrong. In damp conditions or when using metal tools, grounding plus appropriate outlets or GFCI protection adds another layer of safety. The other options don’t address these immediate, high-risk hazards as directly. Gloves can interfere with tool control or get caught in moving parts, keeping the area tidy helps prevent trips but doesn’t stop injuries from debris or shocks, and turning off power after use doesn’t protect you while you’re actively using the tool.
