A colleague is gripping a live conductor — tetanic muscle contraction prevents release. What is the FIRST action?

Question

Accepted Answer

FIRST switch off the power (switch or emergency stop), only then approach the victim — never touch them directly while current is still present — Tetanic muscle contraction (involuntary gripping) occurs with AC above ~10–15 mA and prevents the victim from letting go. Danger to the rescuer: the current flowing through the victim also flows through the rescuer on direct contact. Priority: (1) switch off the power at the nearest switch or emergency stop; (2) if impossible, use DRY insulating material (dry wooden plank, dry jacket) to push/pull the victim free — never touch directly. Step 3: first aid / 112.
