What is the first action to take in case of electric shock while welding?

The first action to take in the event of an electric shock while welding is to disconnect the power. This is critical because the electrical current can cause further harm not only to the victim but also to anyone attempting to help them if the power is not turned off first. The primary objective in such a situation is to eliminate the source of the shock before providing any aid or assistance.

Once the power supply is disconnected, it is safe to assess the situation and provide necessary first aid or call for medical help. Administering CPR or seeking medical assistance should only happen after the electrical source has been removed, ensuring that both the rescuer and the victim are safe from further electrical hazards. The sequence of actions is crucial; without first disconnecting the power, any attempts to help could lead to the rescuer also experiencing an electric shock.
