Step-by-step explanation:
The search priorities for non-residential high-rises include searching for occupants, ensuring stairwell safety, and controlling utilities. When a fire occurs in a high-rise building, it is important to quickly search for any occupants who may be trapped or in danger. Ensuring stairwell safety involves keeping stairwells clear of obstructions and ensuring that they are properly lit and ventilated for safe evacuation. Controlling utilities, such as shutting off gas and electricity, helps prevent further hazards and the spread of fire.
