Emergency Lighting & Exit Sign Inspection Guide

During utility power outages or smoke-filled emergency evacuations, reliable emergency lighting prevents mass panic and guides building occupants along designated exit access corridors. NFPA 101 (Life Safety Code) and local EIT standards govern emergency lighting parameters, battery duration, and maintenance workflows.

1. Core NFPA 101 & EIT Illumination Standards

• Initial Illumination Level: Minimum average of 10.8 lux (1 foot-candle) measured at floor level along the entire path of egress.
• Minimum Illumination Threshold: No single point along the egress path shall fall below 1.1 lux (0.1 foot-candle).
• 90-Minute Battery Autonomy: Emergency battery units must deliver full light output for at least 90 minutes without mains power.

2. Mandatory NFPA 101 Inspection Schedule

1. Monthly Functional Test: 30-second manual battery discharge test to verify lamp illumination.
2. Annual Full Load Discharge Test: Continuous 90-minute discharge test to verify battery storage degradation.
