Final answer:
Exit routes must be unobstructed and sufficiently arranged to facilitate quick and safe escape during emergencies, with clear markings and adequate lighting.
Step-by-step explanation:
Exit routes must be unobstructed, and there must be enough exits in the proper arrangement for quick escape. Properly designed exit routes are crucial for safety in various facilities, including schools, offices, and public buildings. Exit routes must adhere to specific standards to ensure everyone can evacuate promptly and safely during an emergency. These routes should be clearly marked, well-lit, free of any obstructions, and should not lead through high-hazard areas. Regulations also stipulate that there should be a sufficient number of exits based on the building's occupancy and size, as well as the layout of the facility, to prevent overcrowding during an evacuation.
