In the event of a fire or other emergency that causes a power outage in a commercial building, panic and disorientation can set in quickly. When the normal lighting fails, the building is plunged into darkness, making a safe and orderly evacuation extremely difficult. This is why emergency and exit lighting is one of the most critical life-safety systems in any commercial property. These illuminated signs and battery-backed-up lights are designed to activate automatically during a power failure, clearly illuminating the path of egress and guiding building occupants to safety. Proper maintenance and testing of these systems are not just a good idea—it’s a legal requirement.
What Are the Code Requirements?
The standards for emergency and exit lighting are primarily set by the NFPA 101, Life Safety Code®, and are enforced by local fire marshals in the Inland Empire. The core requirements are designed to ensure that the path to safety is always visible, even in a total blackout.
- Illumination: Emergency lighting must provide a minimum level of illumination along the entire path of egress, including hallways, stairwells, and corridors, to prevent trips and falls.
- Exit Signs: All designated exits must be clearly marked with an illuminated sign that is visible from a distance.
- 90-Minute Battery Backup: This is the most critical requirement. Every emergency light and every illuminated exit sign must be equipped with a battery backup system. In the event of a power failure, these batteries must be able to keep the lights on for a minimum of 90 minutes, giving everyone ample time to evacuate the building safely.
The Importance of Regular Testing and Maintenance
A battery backup system is only reliable if it is regularly tested and properly maintained. Over time, batteries lose their ability to hold a charge, and bulbs can burn out. The NFPA 101 code mandates a strict testing schedule for all emergency and exit lighting.
- The 30-Second Monthly Test: Once every 30 days, a building manager must perform a quick functional test. This is done by pushing the “test” button on each unit. The test button temporarily switches the unit to battery power. You must verify that the lights come on and stay lit for at least 30 seconds. A written record of these monthly tests must be kept.
- The 90-Minute Annual Test: Once a year, a much more thorough test must be performed by a qualified technician. This test involves simulating a full power outage and allowing the emergency lights to run on their battery power for the full 90-minute duration. This is the only way to ensure that the batteries are still capable of holding a charge for the required amount of time. Any batteries that fail this test must be replaced.
As the Occupational Safety and Health Administration (OSHA), which sets workplace safety standards, emphasizes, proper exit route illumination is essential for employee safety during an emergency.
Common Points of Failure
- Dead Batteries: Batteries have a finite lifespan and will eventually need to be replaced.
- Burned-Out Bulbs: The lamps in older units can burn out.
- Faulty Charging Circuit: The circuitry that is supposed to keep the battery charged can fail.
- Damage to the Unit: The fixture itself can be damaged during routine building activities.
