In an emergency, the first priority is to stay calm and assess the situation to determine the immediate danger. If necessary, call emergency services for assistance, providing clear details about the situation, the location, and any critical information. If someone is injured or ill, assess their condition: check for breathing and a pulse, and administer CPR if trained. Control bleeding by applying direct pressure to the wound. If there is a fire, smoke, or hazardous situation, ensure your safety first and then evacuate if needed. For medical emergencies, do not attempt to move a seriously injured person unless there is immediate danger. Always be prepared with basic first-aid knowledge, such as how to handle choking, burns, or broken bones, to help stabilize the situation until professional help arrives.
