Which of these are control measures used to mitigate electrical risks and hazards?
Always use the correct current and voltage for the equipment.
Keep the area and clothing dry.
Connect welding equipment properly to complete the circuit.
Always use new cables and leads to avoid wear.
Which of the following are hazards associated with welding operations?
Burns.
Cuts and abrasions.
Electric shock.
