First Aid and Emergency Response and Evacuation

This domain covers immediate life-saving action before medical help arrives, and the organised movement of people out of danger. The exam tests sequence, ratios and the do-not-do rules.

Primary assessment - DRABC

Danger (make the scene safe), Response (speak, squeeze shoulders), Airway (head-tilt, chin-lift), Breathing (look, listen, feel for 10 seconds), Circulation/CPR. Call 112 for emergency services and 108/102 for ambulance in most Indian states.

CPR

  • Adult chest compressions: centre of the chest, depth 5–6 cm, rate 100–120 per minute, ratio 30 compressions to 2 rescue breaths.
  • Use an AED as soon as it is available; follow its voice prompts.
  • If unwilling or untrained to ventilate, do compression-only CPR and keep going until help arrives.

Common emergencies

  • Bleeding: direct pressure with a clean pad, elevate, and use a tourniquet only for catastrophic limb bleeding; record the time.
  • Burns: cool with running water for about 20 minutes, remove rings and tight items, cover with a clean non-fluffy cloth, do not burst blisters or apply toothpaste.
  • Fracture: immobilise in the position found with a splint; do not attempt to straighten the limb.
  • Snake bite: keep the patient still, immobilise the limb at heart level, remove tight items, transport fast. No tourniquet, no cutting, no sucking.
  • Choking: five back blows, then abdominal thrusts (chest thrusts for a pregnant woman or infant).
  • Unconscious but breathing: recovery position, monitor airway.

Worked example. A worker collapses and is not breathing. Reasoning: no breathing after a 10-second check means start CPR, not search for a pulse for minutes. Correct order: shout for help and the ambulance, start 30:2 compressions, send a colleague for the AED, continue until the ambulance or the patient recovers.

Evacuation

Follow the marked escape route to the assembly point, take the roll call against the visitor and contractor registers, sweep toilets and meeting rooms, and never re-enter for belongings.

Traps

  • Giving water to an unconscious person.
  • Moving a suspected spinal injury casualty without need.
  • Not counting and reporting who is missing at the assembly point.
