Introduction to NBC 2025 Egress Safety
Ensuring the safety of occupants during power failures or fire emergencies is a cornerstone of the National Building Code of Canada (NBC) 2025. Proper installation of exit signs and emergency lighting is not just a regulatory requirement but a critical life-safety measure for any commercial or residential multi-unit building in London, Ontario.
Revised Standards for Exit Signage
Under the NBC 2025, exit signs must be clearly visible and identifiable from any point in the exit access corridor. The code continues to mandate the use of the green 'running man' pictogram (ISO 7010) to ensure universal accessibility and clarity.
Visibility and Placement Requirements
- Visibility: Signs must be visible from a distance of 30 meters or less, depending on the specific occupancy type.
- Directional Indicators: If an exit is not immediately visible, directional signs must be placed along the path of travel to guide occupants efficiently.
- Illumination: All exit signs must be internally or externally illuminated at all times the building is occupied.
Emergency Lighting Performance Criteria
Emergency lighting must provide a minimum level of illumination to allow for safe evacuation. The NBC 2025 specifies that the average illumination level must be at least 10 lux at the floor or tread level throughout the exit path.
Duration and Power Supply
- Minimum Duration: Lighting systems must remain operational for a minimum of 30 minutes, though high-occupancy or complex buildings may require 60 to 120 minutes.
- Automatic Activation: The system must activate automatically within 10 seconds of a primary power failure.
- Reliability: Systems must be connected to an emergency power supply, typically battery units or an on-site generator.
