Name two electrical hazards in welding and a basic control for each.

• A. Electric shock — keep dry and insulate workpiece; use insulated gloves; Arc flash — use proper PPE, maintain equipment
• B. Overheating of the wire feed; keep spool tight
• C. Fire hazard from sparks; ignore
• D. Electrical noise; use ear protection

Answer: (A)

Two electrical hazards in welding are electric shock and arc flash. Electric shock occurs when a live electrical part comes into contact with the body or when moisture creates a conductive path, so staying dry, insulating the workpiece to reduce any current path, and using insulated gloves are fundamental protections. Arc flash is a rapid release of energy from a fault in the welding circuit, which can cause burns and eye injuries; protecting yourself with proper PPE (such as a suitable welding helmet, flame-resistant clothing, gloves, and eye/face protection) and keeping equipment well maintained and properly grounded reduces the chance of an arc flash. The other options don’t target electrical hazards in the same way: overheating of the wire feed is more of a equipment issue with different fixes; ignoring sparks is dangerous and not a protective measure; electrical noise relates to sound, not the direct risk of electrical injury.
