Report a Shock

Shock Warning 01
Phone It is critical that all electrical shocks, however minor, be immediately reported to the line manager and to Health Services at ext. 6266 (7:30AM – 3:30PM). AT ALL OTHER TIMES, EMERGENCY MEDICAL SERVICES ARE AVAILABLE FROM THE FIRE DEPARTMENT THROUGH THE 7-911 DISPATCH SYSTEM.
From any LBNL phone on-site or off-site: DIAL 7911
From a 642 or 643 PREFIX: DIAL 9-911
From a cellular phone: DIAL 911
All persons experiencing an electrical shock are to receive appropriate medical evaluation. First Aid

Reporting any shock incident allows us to accomplish three things:
1. First and foremost, make sure you’re OK!
2. Make sure the equipment is safe
3. Improve the Electrical Safety Program

The following are considered severe electrical incidents:

  1. Any loss of consciousness (even if employee is subsequently awake and talking)
  2. Any reported or witnessed prolonged contact (unable to let go)
  3. Any fall or trauma
  4. Obvious burn injury
  5. All high voltage incidents (>750 V) or lightning strikes

Incident Response for a severe electrical incident:

  1. Turn off the electrical power. Do not approach the victim until all electrical power to the area has been disconnected. Alternately, use an insulated rescue hook to move the victim away from the electrical equipment. Do not become a second victim!
  2. Designate someone to call 911 (ext. 7911 from a Berkeley Lab phone) and initiate the Site Emergency Response Plan to get medical assistance. If an ambulance is on the way and in live communication with one of the emergency responders, seek advice from the ambulance team for a treatment plan. Note: In Alameda County, the dispatcher will keep the caller on the line, run through an assessment protocol, and provide instruction for victim handling.
  3. Designate someone to bring back an automated external defibrillator (AED).
  4. Once it is safe to touch the person, begin to administer first aid and assess the need for cardiopulmonary resuscitation (CPR) and/or AED.
  5. If required, administer the AED by following the instructions of the device. Note: All on-site security rovers now carry an AED in their vehicle.
  6. Once Emergency Medical Services (EMS) arrives, turn over the scene. Prevent access to the area where the victim sustained the electrical shock, using barricades and attendants (see section on Alerting Techniques in the Electrical Safety Manual).
  7. Have a Qualified Electrical Worker attempt to determine the cause of the electrical shock, but do not delay medical evaluation of the victim.
  8. In the event of a serious injury, consider the need to preserve evidence for an incident investigation. Do not restore power to the equipment.
  9. Complete an Electrical Incident Report for use by the evaluating physician, but do not delay medical evaluation of the victim. The report is intended to capture as much information as possible about the mechanism of injury, since visible signs are often minimal to the examining physician.

Electrical Injury Report FormMedical evaluation will include a visual examination of the contact points, an electrocardiogram (EKG), a blood test, and an overall evaluation of the injured person’s physical condition. Emergency room evaluation may still be recommended following Health Services’ evaluation.
