Frequently Asked Questions

What color exit signs are required in the U.S.?

In the U.S., exit signs are typically required to display either red or green lettering. The choice depends on regional regulations—places like New York and Chicago generally mandate red lettering for consistency. When considering compliance for your premises, it's essential to align with your local codes and standards, which may differ from other regions.

How often should I test my emergency exit lights?

Exit and emergency lights must be tested monthly with a full functionality assessment and undergo a thorough annual inspection. These routine checks help guarantee safety during power outages. If you're equipping commercial areas, browsing our selection of business emergency lighting can help ensure compliance and readiness.

What is the minimum letter height for exit signs?

According to NFPA codes, the minimum height for letters on exit signs is 6 inches. However, jurisdictions like New York City enforce stricter requirements, often mandating at least 8-inch lettering for enhanced visibility in emergency conditions.

Can I purchase exit signs online or is it better to buy from a safety vendor?

Although purchasing exit signs online is convenient, buying through a specialized safety vendor ensures compatibility with local building codes and proper installation. It's equally important to consider energy-efficient lighting solutions for long-term use, such as LED strip lights, to pair with exits or safety zones.

How long must emergency exit lights remain on during a power outage?

Per the NFPA 101 Life Safety Code, emergency exit lights must remain illuminated for at least 90 minutes following a power failure. This duration ensures safe evacuation and is a major requirement during annual inspections to verify battery capacity and performance.

What type of lighting is most commonly used for exit signs?

LED technology is the most common lighting solution for exit signs due to its superior energy efficiency, consuming just 3 to 5 watts. For added sustainability, consider pairing them with solar lighting solutions throughout other parts of your property for off-grid backup.

Can I install exit signs myself or do I need a professional?

While self-installation is possible, hiring a professional ensures your exit signs are compliant with local codes and function correctly in emergencies. Improper installation can lead to legal liabilities and compromised safety outcomes.

How do self-luminous exit signs work?

Self-luminous exit signs operate using tritium gas, a radioactive isotope that lights up the sign without the need for electricity or wiring. These low-maintenance signs can last up to 20 years and are ideal in locations where uninterrupted power is uncertain. You may also explore long-life illumination options like rechargeable lights for added reliability.
