Final answer:
The search priorities in a high-rise emergency are searching for occupants, ensuring stairwell safety, and controlling utilities. Locating and rescuing people is the top priority, followed by ensuring escape routes are clear and managing utilities to prevent further hazards.
Step-by-step explanation:
The search priorities for a residential high-rise during an emergency, such as a fire, include searching for occupants, ensuring stairwell safety, and controlling utilities. When firefighters enter a burning building, their primary concern is to locate fire victims and rescue victims from the dangerous environment. To achieve this objective safely and effectively, firefighters need to ensure that evacuation pathways, particularly stairwells, are secure and passable. Additionally, managing and shutting off utilities like gas and electricity is vital to prevent further hazards and to control the fire. Proper gear such as fire-resistant clothing and breathing apparatus are essential for firefighters to protect themselves while they assess the fire and report conditions to their superiors to receive further instructions.
