Emergency lights in cinemas are safety requirements mandated to ensure safe evacuation of patrons during power failures or fire emergencies. These lights are specifically installed along exit routes, stairways, and corridors to maintain sufficient illumination for occupants to leave the building safely.

EreqтАЛтЙе1┬аlux тАФ Minimum illumination level required at floor level along escape routes per safety codes.
In the event of a normal power supply failure, an automatic changeover switch (often integrated with a battery-backed Uninterruptible Power Supply or central battery system) energizes the emergency lighting circuit. These circuits are wired independently of the main house lighting to ensure that even if a circuit breaker for the main hall trips, the egress paths remain illuminated.
Emergency lighting must be maintained for a specific duration (typically 60-90 minutes) during a mains power failure.
IE Rules mandate that egress paths must be clearly identifiable even in complete darkness.
Exit signs must be self-illuminating or externally lit by emergency circuits.
Prevents stampedes and panic during emergencies.
Ensures compliance with local fire safety and building codes.
Requires regular battery maintenance and monthly discharge testing.
Higher installation cost due to independent wiring requirements.
Cinema theaters
High-rise commercial buildings
Public assembly halls
Standard: IS 9583-1981 covers the specifications for emergency lighting systems.
Option A (Ticket counter) is incorrect because while important for operations, it is not a safety-critical egress zone requiring dedicated emergency illumination for evacuation.
Option C (Toilet) is not a primary evacuation path and thus does not require emergency lighting to the same stringent standard as exit paths.
B is correct тАФ Emergency lights are mandatory at exits and stairs to facilitate safe evacuation during power failure.
Always remember that in electrical safety exams, priority is given to paths that directly enable egress (exits, corridors, stairs) over operational zones like ticket counters.
