Emergency Lighting Systems for Commercial Structures


Within the electrical system of a commercial building, one of the most important features of the is the emergency lighting. The value of having a network of emergency lighting during a catastrophe or fire should never be underestimated, as it can mean the difference between making it out of a building or not during the emergency event. The electrical building codes reflect the importance of emergency lighting, as there are strict laws regarding the placement and capacity of these lights.

Inspection and regular service by an individual well-versed in OSHA regulations will keep the emergency lighting in a state of perpetual good working order. This is essential as fines are steep if the emergency lighting is not in compliance, and failed re-inspections can rack those fines up into the tens of thousands of dollars. Also, compliance paperwork is critical to avoid legal problems if there is a crisis or disaster.

There are two parts to an emergency lighting network. The first portion is the exit signs. These signs must be properly placed. They are independent units from the emergency lights, and they are either glow-in-the-dark or self-illuminating. 
The second part is the emergency lights, themselves Although emergency lights are part of the primary lighting system, they have independent controls. If the electrical system is operational after an event, the emergency lights will operate from the main power system. However, if this is not the case,  the system has its own ballast network which connects the lights to an emergency lighting battery system. 


In the event of emergency circumstances, if the primary power fails, the lighting system must be capable of battery-powered operation for a least 1.5 hours, although the newer systems are much more effective and will last about 30% longer. While occupants will presumably be evacuating briskly from the building, firefighters and other personnel will still have a brief time to enter the building to conduct emergency procedures and move the injured out.

The lighting pattern must be correctly set to guide individuals within a building toward an exit by providing illumination all the way up to the exit and all the way out of the building. Emergency lights are a ‘trail of breadcrumbs’ to get potentially confused and frightened occupants out of the structure without further injury, and a building owner with compliant lighting can be proud to call his facility a safe one.
