Stop After a Shock or Electrical Near Miss

Know the hazard

Team: Electricians. Topic: Incident Response.

A tingling sensation, a tool shock, a flash, or unexpected tripping is information about a possible failure. Do not dismiss it because the worker is still standing or the equipment runs again. Electrical injuries can be serious even when the surface injury looks minor. The first priorities are to stop exposure, protect others, and obtain appropriate emergency assistance.

Use the controls

If someone remains in contact with electricity, do not touch them or the equipment. Alert others, call emergency services, and have electrical isolation arranged through the appropriate safe means and personnel. Provide first aid or resuscitation only when the scene is safe and within your training. Follow the site emergency plan and obtain medical evaluation after an electrical exposure as directed.

Work within the safe plan

Secure the affected area and keep equipment out of service until responsible qualified personnel investigate and release it. Do not repeatedly reset, change plugs, or try the tool in another outlet to see whether it happens again. Preserve useful information about the task and conditions without entering the hazard. Today, practice reporting the exact location, equipment involved, and whether the electrical source is still uncontrolled so responders can approach safely. Before the crew begins, ask someone to explain the control in their own words and point to the person responsible for confirming it. Resolve uncertainty now, while the task is still paused.

Discuss with the crew

A worker feels a shock from a metal tool housing and offers it to a coworker to confirm the problem.

Question: What should happen instead?
Answer guidance: Stop use, keep others clear, report the event, and arrange medical and qualified equipment evaluation as appropriate.

Question: Why not test the tool by touch?
Answer guidance: That deliberately exposes another person to a potentially dangerous electrical fault.

Prepare, act, and follow up

Leader preparation: Confirm emergency numbers, reporting contacts, and the safe route for emergency responders.

Put it into practice: Rehearse the emergency location message and identify how defective equipment is prevented from reuse.

Supervisor follow-up: Investigate the cause and confirm medical follow-up and documented equipment release before return to service.
