Emergency lights and exit signs are an integral component of all commercial buildings. While not always used daily, they can make all the difference in times of emergency. Because of that, it’s important to consider things like material, lumens and safety code certifications when installing emergency lighting. The vast majority of exit signs and emergency lights are made of thermoplastic, which is very durable and can withstand higher temperatures. Aluminum is another popular option and is often paired with acrylic panels. These “Edge-Lit” signs create a transparent and floating effect.
Some codes to be aware of when shopping for exit and emergency lighting are UL 924, NFPA 101 Life Safety Code, NEC and OSHA, which all determine specific safety requirements for electrical products. Other important aspects to consider are the kind of battery in the unit, if there’s a backup battery to provide illumination during a power outage and if it contains self-diagnostics and will perform automatic code compliance testing.
Exit and emergency signage must be inspected by a certified technician. The number and placement of exit signs and emergency lights in your facility will be subject to local requirements, so be sure to consult local and state regulations.
Common Safety Codes
UL 924: The UL 924 rating means that the product is certified to meet certain functionality and reliability requirements including emergency operation for at least 90 minutes.
NFPA 101 Life Safety Code: This code covers minimum requirements for design, construction and maintenance that will protect occupants from danger caused by fire and related hazards.
NEC: The National Electrical Code determines safe installation and wiring standards and requires emergency lighting be energized within 10 seconds and for 90+ minutes during an outage.
OSHA: The Occupational Safety and Health Administration standards are methods that employers must use to ensure safe and healthful working conditions for their employees.
