Emergency Response, Firefighting and First Aid
Domain focus
This domain tests emergency response, firefighting, and first aid: alarms, muster, fire classes, extinguisher selection, H2S response, casualty assessment, bleeding control, burns, and CPR. Questions often ask for the first safe action.
Core rules
- Follow the emergency response plan: raise the alarm, stop work, account for personnel at muster, and follow incident command. Do not re-enter without authorization.
- Fire needs fuel, oxygen, and heat. Use the correct extinguisher: water for Class A only; foam for flammable liquids; CO2 or dry powder for energized electrical; dry powder for gas fires. Never use water on live electrical or oil fires.
- Use PASS: pull the pin, aim at the base, squeeze the handle, sweep. Fight only a small, incipient fire with a clear escape route.
- For H2S, move upwind and uphill, use SCBA, and never attempt a rescue without breathing apparatus and backup.
- First aid: check danger, response, airway, breathing, and circulation; call for help; control severe bleeding; cool burns with running water; do not move a suspected spinal casualty unless necessary.
Worked example
A small electrical panel fire starts in a rig cabin. The reasoning is: isolate the power if safe, raise the alarm, evacuate non-essential people, and use CO2 or dry powder only if trained and the fire is small. If the panel remains energized or smoke spreads, withdraw and let the emergency team handle it.
Traps
Using water on an electrical fire; entering an H2S area without SCBA; delaying the alarm to fight a fire; moving an injured person before checking for spinal injury.
