Ensuring Safety and Adherence to OSHA & NFPA Regulations
For procurement managers, project engineers, and MRO professionals, the responsibility of ensuring a facility’s safety is paramount. While complex machinery and large-scale systems often take center stage, some of the most critical safety components are the ones we see every day: exit signs and emergency lighting. These are not merely fixtures but essential elements of a building’s life safety system, designed to guide people to safety during an emergency. Understanding and adhering to the strict standards set by regulatory bodies is not just a matter of compliance—it’s a fundamental commitment to protecting lives. Partnering with a knowledgeable supplier for your safety products is the first step in building a robust safety infrastructure.
Understanding the “Why” Behind the Regulations
The primary function of exit signs and emergency lights is to provide a clear, illuminated path of egress during a crisis, such as a fire, power outage, or other hazardous events. When normal power is lost and visibility is compromised, these systems activate automatically to prevent panic and guide occupants to safety. Two key organizations govern the requirements for these systems in the United States:
- The Occupational Safety and Health Administration (OSHA): OSHA mandates that all exit routes must be adequately lit and clearly marked, ensuring that employees can safely navigate their way out of a facility in an emergency.
- The National Fire Protection Association (NFPA): Specifically, the NFPA 101, Life Safety Code®, provides detailed standards for the placement, illumination, and testing of emergency lighting and exit signs. These guidelines are widely adopted into local and state building codes.
Non-compliance carries significant risks, including heavy fines, legal liability in the event of an incident, and most importantly, a failure to protect the people within your facility. A comprehensive understanding of these standards is essential for anyone responsible for sourcing fire protection equipment and safety systems.
Key Requirements for Exit Signs
Visibility and Placement
According to OSHA and NFPA standards, exit signs must be unmistakable. This means they must be illuminated, use legible letters (typically at least 6 inches high), and be placed so that no point in an exit access corridor is more than 100 feet from the nearest visible sign. They must clearly mark all exits and the paths leading to them.
Illumination and Power Sources
Signs must be lit by a reliable source and be visible in both normal and emergency conditions. Modern facilities have several options, each with distinct advantages:
- LED Signs: The most common choice today, LED signs are highly energy-efficient, have a long service life, and provide bright, consistent illumination.
- Photoluminescent Signs: These “glow-in-the-dark” signs absorb ambient light and release it slowly when power is lost. They require no electricity or batteries, making them a sustainable and low-maintenance option where sufficient charging light is available.
- Self-Luminous Signs: Using tritium gas, these signs provide constant illumination for 10-20 years without any external power. However, they require special disposal procedures due to their radioactive content.
Demystifying Emergency Lighting Standards
Emergency lighting activates automatically during a power failure, providing essential illumination along the path of egress. The NFPA 101 code outlines specific performance requirements to ensure effectiveness.
Illumination Levels
The path of egress must be illuminated to an average of at least 1.0 foot-candle (10.8 lux) at the floor level. The minimum illumination at any single point must be no less than 0.1 foot-candle (1.1 lux). This ensures there are no dangerously dark spots along the escape route.
Duration and Activation
Emergency lighting must stay illuminated for a minimum of 90 minutes after normal power is lost. The system must activate automatically within 10 seconds of a power failure, ensuring a seamless transition and continuous visibility.
A Practical Checklist for Maintenance and Testing
Installation is only the first step. Regular testing and maintenance are required by law to ensure systems function when needed. Keeping detailed records of these tests is crucial for compliance audits.
Monthly Inspection (30-Second Test)
Once every 30 days, a functional test must be performed. This involves activating the test button on each unit for at least 30 seconds to verify that the lamps illuminate and the battery is connected. A visual inspection for any physical damage should also be conducted.
Annual Inspection (90-Minute Test)
Annually, a full-duration test is required. The system must run on its backup power for the full 90 minutes to ensure the batteries can hold a charge and perform as required during a prolonged outage. Any units that fail must be repaired or replaced immediately.

Frequently Asked Questions
How often do emergency lights need to be tested?
Emergency lights require a 30-second functional test monthly and a full 90-minute duration test annually. Records of these tests must be maintained.
What’s the difference between maintained and non-maintained emergency lighting?
Maintained emergency lights are always on and function as part of the normal lighting system, switching to battery power during an outage. They are common in public venues. Non-maintained lights only turn on when normal power fails and are often used in workplaces where occupants are familiar with the layout.
Are red or green exit signs better?
Both red and green are compliant colors in the U.S. The choice often depends on local codes and facility aesthetics. Green is sometimes considered easier to see in smoky conditions and is the international standard, but red is more traditional in many parts of the country.
What are the consequences of non-compliance with emergency lighting standards?
Non-compliance can lead to significant OSHA fines, denial of insurance claims, and severe legal liability in case of an accident. Most importantly, it puts building occupants at a much higher risk of injury or death during an emergency.
Can I use photoluminescent exit signs in any building?
Photoluminescent signs are an excellent, energy-efficient option, but they must be placed where they can receive at least 5 foot-candles of ambient light from fluorescent, metal halide, or mercury vapor lights to charge properly. They may not be suitable for dimly lit areas.
Glossary of Terms
Foot-candle: A standard unit of illuminance, or the amount of light reaching a surface. One foot-candle is equivalent to one lumen per square foot.
NFPA 101: Also known as the Life Safety Code®, it’s a standard from the National Fire Protection Association that provides strategies to minimize the effects of fire and related hazards.
OSHA: The Occupational Safety and Health Administration, a U.S. government agency that ensures safe and healthful working conditions by setting and enforcing standards.
Path of Egress: A continuous and unobstructed way of exit travel from any point in a building to a public way. It consists of three parts: the exit access, the exit, and the exit discharge.
Photoluminescent: A material that has the property of glowing in the dark after being charged by an ambient light source. It does not require electricity or batteries.
