Emergency and exit path lighting are required in all commercial buildings. Think about it, power failures occur often. It could be from lightning, downed power lines, or just an interruption in service. Your employees and customers need to safely move around your buildings at the time of power failure. The need for these devices is essential. If there were a fire and swift escape was crucial, the combination of smoke and power failure would make visibility nearly impossible without proper emergency lighting. In your plan of protecting life and property at the time of an emergency, lighting is a critical component. The fire code requires that your illumination work for a minimum of 90 minutes when called to do so. Documents indicating that this test has been completed are required along with a monthly quick check of your units. At Tri State, the majority of our customers perform this quick check themselves and have us perform the 90 minute test and deliver the proper documentation that will help ensure you that your lighting will work when you need it most.
