First Aid for Electrical Shock: Critical Steps to Save Lives
By Muhammad Adnan Chattha··
Learn vital first aid steps for electrical shock in Pakistan. Discover immediate response protocols to prevent fatalities during electrical accidents.
Electrical accidents occur without warning and escalate within fractions of a second. In Pakistan, where the standard domestic power supply runs at 230 volts (single-phase) and industrial infrastructure operates at 400 volts up to 11 kilovolts (kV), contact with energized components can cause catastrophic trauma. The outcome of an electrical shock incident depends almost entirely on the actions taken within the first three to four minutes. When an individual comes into contact with live current, the human body acts as a conductor, leading to severe muscular tetany (the inability to let go), respiratory paralysis, cardiac arrest, and deep thermal burns. Understanding precise, step-by-step first aid protocols can mean the difference between immediate resuscitation and a fatal outcome.
Immediate Assessment: Securing the Scene Without Becoming a Victim
The primary instinct when watching a colleague or family member collapse from an electric shock is to reach out and pull them away. In an electrical emergency, acting on instinct without assessing the environment often creates a second victim. The current will effortlessly pass from the casualty into the rescuer, incapacitating both. Before moving a single step toward the victim, you must evaluate the voltage source, the physical environment, and potential paths of conduction.
In Pakistani residential and industrial environments, secondary conduction hazards are widespread. Standing water, ungrounded metal conduits, reinforced concrete floors, and metal roofing sheets can all remain energized if in contact with a severed wire. High ambient humidity during the monsoon season lowers skin resistance, accelerating the flow of current. If the accident involves overhead lines—such as an uninsulated 11kV feeder line snapped during a storm—the ground itself becomes energized around the point of contact in concentric voltage rings (known as step potential). In high-voltage scenarios above 1,000 volts, you must stay at least 10 meters (33 feet) away until the local utility distribution company (such as FESCO, LESCO, or K-Electric) isolates the grid.
For low-voltage accidents inside buildings (under 1,000V), assess whether you can safely approach without stepping into standing water or touching conductive metal surfaces. Check for hazards such as spilled liquids, dangling conductors, or damaged control panels before planning your approach to break the electrical circuit.
Safe Separation: How to Disconnect the Victim from the Current
The most critical priority in low-voltage electrical first aid is terminating the current flow. If the victim is still frozen against the conductor due to involuntary muscle contraction, do not attempt physical contact. Instead, locate the source of isolation immediately:

1. Cut the Power Source: Rush to the main distribution board (DB) and switch off the main double-pole Miniature Circuit Breaker (MCB) or Molded Case Circuit Breaker (MCCB). Pulling the plug from a wall socket or turning off an appliance switch is insufficient if internal wiring faults are feeding the circuit.
2. Use Non-Conductive Material: If the switchboard is inaccessible, submerged, or locked, use a dry, clean, non-conductive object to push or pull the casualty clear. Use seasoned dry timber, a fiberglass pole, a broom handle made of dry unfinished wood, or heavy industrial dry PVC conduit.
3. Avoid Conductive Hazards: Never use damp wood, metallic rods, wet cloths, or items with metal fastenings. Ensure your hands and feet are dry; standing on a dry rubber mat, wooden board, or folded cardboard provides an extra layer of insulation against ground faults.
4. Dislodge with Caution: Strike or shove the live wire away from the victim, or push the victim’s limbs away from the conductor in one deliberate, forceful movement. Never attempt to wrap your arms around the person's clothing to drag them away, as moisture, sweat, or synthetic clothing can conduct electrical currents directly into your body.
Once the current is broken and the area is verified as de-energized, you can proceed directly to medical evaluation without risk of shock.
Emergency Medical Response: Triage, CPR, and Vital Checks
Once the victim is clear of the electrical source, time is of the essence. Electrical shock directly disrupts the heart’s intrinsic electrical conduction system, frequently triggering ventricular fibrillation—a chaotic, ineffective quivering of the heart muscles that halts blood circulation. Follow the standard DRSABCD emergency sequence:
* Check Response: Tap the casualty’s shoulders firmly and shout loudly in both Urdu and English. If there is no response, check the airway immediately.
* Open the Airway: Tilt the head back gently while lifting the chin. Because severe electric shocks can throw a victim backward or cause a fall from a height, handle the neck with care to avoid aggravating potential spinal trauma.
* Check for Normal Breathing: Place your ear near the victim's mouth and nose while watching the chest for five to ten seconds. Do not mistake agonal gasps (irregular, snorting gasps) for normal breathing; agonal breathing is a clear sign of cardiac arrest.
If the patient is unconscious and not breathing normally, begin Cardiopulmonary Resuscitation (CPR) without hesitation. Place the heel of one hand in the center of the chest, interlock your fingers with the other hand, and compress hard and fast at a rate of 100 to 120 beats per minute, depressing the chest 5 to 6 cm (2 to 2.5 inches). Maintain a ratio of 30 compressions followed by 2 rescue breaths if trained, or perform continuous hands-only CPR if rescue breaths are not possible. If an Automated External Defibrillator (AED) is present on an industrial site, power it on immediately and follow the spoken prompts. Continue CPR until the victim shows signs of life, emergency medical personnel arrive, or you are physically unable to continue.
Treating Electrical Burns and Secondary Trauma
Electrical burns are deceptive. Unlike thermal burns caused by direct fire or hot surfaces, electrical burns generate damage from the inside out as the current encounters bodily resistance, transforming into intense internal heat.
The visible surface damage typically shows an "entry" wound (where the current touched the skin, often leaving a charred, punctate, or blistered mark) and an "exit" wound (where the current grounded out, frequently on the feet or opposite hand). Internal damage often involves massive destruction to deep muscles, nerves, blood vessels, and bone tissue, even when the skin appears intact.
To manage burns post-shock:
* Cool the Burn: Flood superficial entry and exit wounds with clean, cool, running tap water for at least 20 minutes.
* Do Not Use Home Remedies: Do not apply ice, iced water, toothpastes, mustard oil, or raw eggs—remedies frequently used in domestic Pakistan that trap heat and guarantee severe bacterial infections.
* Protect the Wound: Cover the wounds with sterile, non-adherent gauze or clean, lint-free cotton cloth. Do not burst blisters or remove melted clothing stuck to the flesh.
* Anticipate Internal Complications: Large-scale muscle breakdown releases myoglobin into the bloodstream, which clogs the renal tubules and causes acute kidney failure within 24 to 48 hours. Any victim exposed to medium or high voltage must be moved to an advanced tertiary care facility for fluid resuscitation, regardless of how well they feel immediately after the event.
Pakistan Emergency Protocols: Alerting Rescue 1122 and Hospital Care
While first aid is underway, coordinate the professional medical evacuation. In Punjab, Khyber Pakhtunkhwa, and urban centers across Sindh and Balochistan, dial 1122 to mobilize emergency medical technicians. If 1122 is unavailable in remote areas, contact the nearest Edhi foundation post (dial 115) or Chhipa service (dial 1020).
When reporting an electrical accident to the dispatch operator, state the exact nature of the incident:
* Confirm that it is an electrical shock trauma.
* State whether high-voltage transmission or domestic low-voltage is involved.
* Report whether the patient is conscious, whether CPR is actively in progress, and if severe burns or falls are present.
* Provide an unambiguous physical landmark, especially in dense industrial zones such as Faisalabad’s Small Industrial Estate or Karachi’s SITE area, where narrow roads can delay ambulances.
While waiting for the ambulance, manage the casualty for shock. If the victim is breathing and has no spinal injuries, position them on their side in the recovery position to keep the airway clear of vomit or fluids. Keep the victim warm with a light blanket to prevent hypothermia, which accelerates circulatory collapse.
Post-Incident Electrical Inspection and Prevention Costs
First aid manages the human tragedy, but preventing recurrence requires immediate remediation of the installation. Electrical shocks are rarely random; they are symptoms of missing earthing systems, defeated protective devices, or substandard wiring. Abdullah International has observed across industrial sites since 2003 that most electrical shock events stem from bypassing Residual Current Devices (RCDs) or using ungrounded sub-distribution circuits.
After an incident, the entire circuit must be locked out, tagged out (LOTO), and subjected to insulation resistance testing before re-energizing. Remedying these hazards requires clear financial investment, which pales in comparison to the cost of human life or industrial downtime:
| Protective Measure | Purpose | Approximate Cost (PKR) |
| :--- | :--- | :--- |
| Residual Current Device (RCD / RCCB) | Trips supply in under 30ms if leakage exceeds 30mA | PKR 4,500 – 12,000 per unit |
| Complete Chemical Earthing Pit | Establishes low-resistance earth return (<5 Ohms) | PKR 45,000 – 85,000 per pit |
| Class 0 Insulating Gloves (1000V rated) | Essential PPE for maintenance personnel | PKR 8,000 – 16,000 per pair |
| Non-Conductive Fiberglass Rescue Hook | Safe separation tool for electrical panels | PKR 15,000 – 25,000 per unit |
| Periodic Insulation Resistance Testing | Megger test to identify degraded insulation early | PKR 25,000 – 50,000 per audit |
A structured assessment by licensed professionals, such as the engineers at Abdullah International, guarantees that installations comply with Pakistan Engineering Council (PEC) standards and international electrical safety codes, preventing life-threatening leakage before it manifests.
Conclusion
The first four minutes following an electrical shock dictate the victim’s survival. Memorize the critical protocol: isolate the power immediately, break contact only with certified non-conductive tools, begin high-quality CPR if the victim is unresponsive, and immediately mobilize emergency teams via 1122. Never treat an electrical shock casualty casually, even if they regain consciousness quickly, as internal cardiac arrhythmias and cellular muscle damage can turn fatal hours after the event. Audit your facility’s distribution switchgear today, verify your earthing resistance levels, and ensure functional earth-leakage protection is installed across every energized panel.
