Which of the following are not a concern when it comes to electrical hazards?

• A. Rubber, wood, or dry PPE
• B. Rubber gloves
• C. Wet gloves
• D. Metal tools

Answer: (A)

Electrical hazards arise when current can find a path through moisture or conductive materials, so insulation and dryness are what protect you. Dry rubber, wood in its dry state, and dry PPE all act as barriers to current, so they don’t introduce a risk by themselves. Wet gloves, by contrast, increase conductivity and create a path for electric shock, which is why moisture is a hazard. Metal tools can conduct electricity and become energized paths, also increasing risk. So the items that are not a concern are those dry, non-conductive barriers, while moisture and metal tools are what you need to watch out for.
