An electrical shock response plan matters most for the injuries that look minor. A serious electrocution triggers an obvious emergency response. The harder problem is the worker who gets “just a zap,” shakes it off, and goes back to work. Shocks like that are frequently never reported, never evaluated, and never investigated, which means the employer learns about the hazard only after the next contact is worse.
This guide is written for safety directors and operations leaders at electrical contractors, industrial facilities, and energy employers. It lays out what to do from the first seconds after contact through medical evaluation, OSHA recordkeeping and reporting, and a safe return to duty.
Why Every Electrical Shock Needs a Response Plan
Electrical injuries are unusual because the visible damage can be the smallest part of the injury. Current can travel through the body along a path that is not visible from the outside, and a worker can appear normal immediately after contact. That is why many organizations treat every shock as a medical event. Lawrence Berkeley National Laboratory’s electrical emergency response requirements, for example, require evaluation by a health professional, including an ECG, after any electrical incident, noting that delayed heart rhythm problems can occur after a shock.
A written plan protects the employer in three ways: it gets the right level of care to the worker fast, it captures the facts needed to fix the hazard, and it produces accurate records instead of guesses.
Step 1: The First Minutes After Electrical Contact
1. Do not touch the worker if they may still be in contact with the source. De-energize the circuit or equipment first, or use approved rescue methods and tools.
2. Call 911 if any emergency sign in the table below is present.
3. Start CPR and use an AED if the worker is unresponsive and not breathing normally. Electric shock can cause cardiac arrest, which is why OSHA’s electric power standards require CPR-trained workers and set two-person and 4-minute rescue rules for energized work. We cover those rules in our wind and solar first aid guide.
4. Secure the scene so no one else is exposed, and keep the area as undisturbed as possible for the investigation.
| Call 911 immediately | Same-day medical evaluation |
| Loss of consciousness, any duration | Brief contact, worker alert and talking normally |
| Not breathing normally, chest pain, palpitations, or shortness of breath | Tingling or numbness that resolves |
| High-voltage contact (Berkeley Lab uses more than 750 volts) or lightning | Low-voltage contact with no emergency signs |
| Could not let go of the source, or prolonged contact | Worker “feels fine” but had a shock |
| Visible burns, especially at entry and exit points | Minor skin marks with no other symptoms |
| A fall, confusion, seizure, or any doubt at all | Any shock not covered in the left column |
| When in doubt, call 911This table is a planning aid, not a substitute for clinical judgment. Your medical director should approve the criteria in your plan, and any uncertainty on site should default to emergency services. |
Step 2: Report Every Shock, Including the Minor Ones
The biggest gap in most electrical safety programs is reporting. Workers often treat small shocks as part of the job, especially on residential and light commercial work. Your plan should say plainly that every shock is reported, the same shift, with no penalty. Workers must never be discouraged from reporting injuries or seeking care; OSHA’s anti-retaliation rule at 29 CFR 1904.35 protects that right.
Reported shocks are valuable data. Each one is a near-miss that points to a failed lockout, a missed test-before-touch, damaged tools or cords, or work that should have been de-energized.
Step 3: Get the Right Medical Evaluation
For shocks with emergency signs, the emergency department is the right place. For the far more common minor shocks, an evaluation by an occupational medicine provider is usually the faster and more appropriate route. A typical post-shock evaluation includes:
- A history of the contact: voltage, AC or DC, the likely path through the body, duration, and whether the worker could let go
- An exam for burns at contact points and for neurological symptoms
- An ECG, and further testing if the history, exam, or ECG raises concern
- Clear instructions on delayed symptoms that require re-evaluation
On remote sites and night shifts, remote physician triage lets an occupational medicine physician assess the situation by video and direct the worker to the right level of care. For in-person evaluation, our workplace urgent care handles workplace injuries with same-day reporting to the employer.
Step 4: Document and Investigate the Incident
Capture the facts while they are fresh. Your incident record should include:
| Record this | Why it matters |
| Voltage, AC or DC, and the equipment or circuit involved | Drives the medical evaluation and the hazard fix |
| Contact points and likely current path | Guides the clinician and identifies the failure |
| Duration of contact and whether the worker could let go | A key severity indicator |
| Task being performed, and whether it was energized work | Tests whether an energized work permit was required and followed |
| Lockout/tagout and test-before-touch status | The most common root cause in shock incidents |
| PPE and tools in use, including condition | Identifies damaged or inappropriate equipment |
| Witnesses and time of each response step | Supports the investigation and any later review |
Most electrical safety programs built on NFPA 70E already require an incident investigation process. Tie the medical side of the response into that process so the clinical findings and the root-cause findings sit in one record.
Step 5: OSHA Recordkeeping and Reporting After a Shock
Recordability depends on what happened to the worker and what care was needed, not on the fact that a shock occurred. Under 29 CFR 1904.7, visits solely for observation and diagnostic procedures are not medical treatment. That leads to these common outcomes:
| Scenario | Recordable? | Why |
| Brief shock, clinic evaluation with ECG, cleared, back to work | No, on that basis alone | Observation and diagnostic tests are not medical treatment |
| Minor skin burn treated with a non-prescription dressing | No | First aid |
| Loss of consciousness for any length of time | Yes | 1904.7(b)(6) requires recording any loss of consciousness |
| Burn treated with prescription medication or professional wound care | Yes | Medical treatment beyond first aid |
| Days away, restricted work, or job transfer | Yes | General recording criteria |
Separately, OSHA requires employers to report a work-related fatality within 8 hours and an in-patient hospitalization, amputation, or loss of an eye within 24 hours. Hospital admissions solely for observation or diagnostic testing are not reportable. For worked examples of the first aid line, see first aid vs. OSHA recordable: construction examples.
| Never skip care to protect the logThe evaluation after a shock is diagnostic, and the recordkeeping rules already account for that. Skipping or delaying evaluation to avoid a record puts the worker at risk and creates far larger liability than any entry on the OSHA 300 log. |
Step 6: Return to Duty and Follow-Up
A worker should return to duty after a clinician clears them. Give every worker who had a shock clear instructions to report delayed symptoms, such as palpitations, chest pain, numbness, weakness, persistent headaches, or trouble concentrating, and make re-evaluation easy. Supervisors should check in over the following days rather than treating the case as closed on day one.
Close the loop on the hazard as well: corrective actions from the investigation should be assigned, completed, and shared with crews doing similar work.
What a Written Electrical Shock Response Plan Saves
- Missed injuries. Early evaluation finds the problems that are hardest to see, before they become the most expensive claims.
- Unnecessary ER visits. Clear criteria send emergencies to the ER and minor shocks to faster, lower-cost occupational care.
- Accurate records. Correct recordkeeping protects your TRIR and the experience modification rate that affects bids and premiums.
- The next incident. Every reported shock is a chance to fix a failed control before it causes a fatality.

Frequently Asked Questions
Does a worker need a medical evaluation after a minor electrical shock?
It is best practice. A worker can feel fine after a shock and still have an injury that is not visible, and some organizations, such as Lawrence Berkeley National Laboratory, require evaluation by a health professional, including an ECG, after any electrical incident. The evaluation can often be done quickly at an occupational health clinic or started through telemedicine triage when there are no emergency signs.
When should an employer call 911 after an electrical shock?
Call 911 immediately if the worker lost consciousness, is not breathing normally, has chest pain, palpitations, or shortness of breath, contacted high voltage, could not let go of the source, has visible burns, fell, or is confused. When in doubt, call 911. Never touch a worker who may still be in contact with an energized source.
Is an electrical shock an OSHA recordable injury?
It depends on the outcome, not the shock itself. Under 29 CFR 1904.7, visits solely for observation and diagnostic procedures such as an ECG are not medical treatment, so a shock that is evaluated and cleared is not recordable on that basis alone. It is recordable if the worker lost consciousness for any length of time, needed medical treatment beyond first aid, or had days away, restricted work, or job transfer.
Does an electrical shock have to be reported to OSHA?
Employers must report a work-related fatality to OSHA within 8 hours and an in-patient hospitalization, amputation, or loss of an eye within 24 hours. OSHA does not require reporting of hospital admissions solely for observation or diagnostic testing. Every shock should still be reported internally and investigated.
When can a worker return to duty after an electrical shock?
After a clinician has evaluated the worker and cleared them, based on the history of the shock, the exam, and any tests such as an ECG. Workers should be told to report delayed symptoms such as palpitations, chest pain, numbness, weakness, or headaches in the following days so they can be re-evaluated promptly.
