🔍 Key Concepts

• electrical safety practices in arc welding • how insulation, dryness, and environment each affect shock risk • the meaning of a choice that groups other choices (e.g., “all of the above” type answers)

💭 Think About

• For each of the first three choices, ask: would this action reasonably reduce my body’s chance of becoming part of the electrical circuit? • Think about whether using insulated holders, wearing dry gloves, and staying out of wet areas are independent safety measures or overlapping ones. • Consider what exam writers usually do when several individual safety steps are all valid and commonly recommended in training materials.

✅ Before You Answer

• For each of A, B, and C, decide yes or no: does this clearly reduce electric shock risk during arc welding? • Verify whether water or dampness increases electrical conductivity and therefore shock risk. • Check if it’s common in safety guidance to combine multiple protective measures instead of relying on just one.
