A worker who is in contact with an electrical source may not be conscious or may be experiencing "muscle clamping" where the releasing of the conductor is impossible because of the involuntary contraction of muscles due to current flow. A rescuer attempting to pull the victim from the source of electricity may themselves become energized and become a victim. When approaching a victim, caution should be the primary consideration as well as performing an effective and speedy rescue. Safely de-energize the electrical equipment if possible at the disconnect switch, circuit breaker, emergency shut-off device, removing the power source, etc. Contact emergency response personnel as soon as possible.
Considerations if the power source cannot be disconnected:
Start CPR and first aid as soon as it can be safely performed. Every minute counts to increase the victim's chance of survival.
The NFPA 70E Article 110.2(C)(1) Training Requirements Emergency Response Training Contact Release. Requires emergency response training for employees who work with energized electrical equipment and are exposed to shock hazards with annual refresher training.
OSHA and the NFPA (Article 110.2(C)(2) Resuscitation) require that the employers regularly train (verified annually) the employees who are responsible for responding to medical emergencies in the absence of medical personnel, which includes first aid, procedures, approved methods of resuscitation, cardiopulmonary resuscitation (CPR) as well as the use of automated external defibrillator (AED).
Though not mandatory for non-medical emergency response personnel, all employees should be trained in the basic first aid, cardiopulmonary resuscitation CPR and automated external defibrillator (AED) use.
Formal CPR and AED training is typically provided by the employer though outside training organizations such as the American Red Cross.
