Introduction to NBC 2025 Exit Signage Standards
Ensuring the safety of occupants during an emergency is a core pillar of the National Building Code of Canada (NBC) 2025. Proper exit signage and directional markers are not merely aesthetic choices; they are critical life-safety components. For those working with empcontracting.ca Inc. your construction contractor in London, Ontario, understanding these technical requirements is essential for project approval and building safety.
Visibility and Placement Requirements
Under the NBC 2025, every exit door must have a compliant exit sign placed over or adjacent to it if the exit is not immediately visible to the occupants. In large open-plan spaces or complex corridors, directional markers must be installed to guide individuals toward the nearest exit. These signs must be visible from any point in the exit access corridor at a distance specified by the occupant load and building classification.
Illumination and Power Supply Standards
The 2025 code emphasizes reliability. Exit signs must be illuminated either internally or externally while the building is occupied. In the event of a power failure, emergency lighting must automatically power these signs for a minimum duration—typically 30 to 60 minutes depending on the building type—to ensure safe egress during a blackout.
The ISO 'Running Man' Symbol
The NBC 2025 continues the transition toward universal pictograms. The green 'Running Man' (ISO 7010) is the mandatory standard for new construction in Ontario. This symbol ensures that language barriers do not impede safety, providing clear, intuitive direction for all residents and visitors in London.
Tactile and Braille Requirements for Accessibility
To align with evolving accessibility standards, directional markers must now often include tactile elements. This ensures that visually impaired occupants can navigate to emergency exits safely, reflecting the code's commitment to inclusive safety design in modern Ontario architecture.

Navigating the nuances of the NBC 2025 requires local expertise. When you partner with empcontracting.ca Inc. your construction contractor in London, Ontario, you ensure that every sign, light, and marker meets the rigorous inspections of the City of London’s building department.
