"In London, Ontario, municipal inspectors are increasingly stringent regarding the visibility and power-source reliability of egress markings during final occupancy reviews. At empcontracting.ca Inc. your construction contractor in London, Ontario, we integrate these life safety components at the early framing and electrical stages to ensure your project passes inspections the first time while providing maximum occupant safety."
Understanding the National Building Code (NBC) 2025 Standards for Exit Signs
In the latest iteration of the National Building Code of Canada (NBC) 2025, the focus on life safety and egress visibility has been sharpened. Standardized signage is not merely a preference but a mandatory safety requirement for all commercial and multi-unit residential buildings. As empcontracting.ca Inc. your construction contractor in London, Ontario, we ensure that every project adheres to these critical safety protocols.
The 'Running Man' Pictogram and Visibility Standards
The NBC 2025 continues to mandate the use of the ISO 7010 'Running Man' pictogram. Exit signs must be clearly visible from all areas within the floor space and must be placed at every exit door leading to a hallway, staircase, or the building exterior. The code specifies that these signs must be green and white, replacing the older red 'EXIT' text signs to align with international safety standards.
Illumination and Emergency Power Supply
Illumination is a core pillar of the 2025 egress marking code. All exit signs must be internally or externally illuminated. In the event of a power failure, these signs must be connected to an emergency power supply, typically a battery backup or a dedicated emergency generator, capable of providing illumination for a minimum of 30 to 120 minutes depending on the building's occupancy classification. Our team at empcontracting.ca Inc. your construction contractor in London, Ontario specializes in integrating these electrical requirements into your building's infrastructure seamlessly.
Tactile and Low-Level Egress Markings
To enhance accessibility and safety in smoke-filled environments, the NBC 2025 emphasizes supplemental egress markings. This includes photoluminescent (glow-in-the-dark) strips along floor-level paths and tactile exit indicators for the visually impaired. These additions ensure that occupants can navigate the egress route even when visibility is severely compromised at eye level.
Inspection and Maintenance Compliance
Compliance does not end at installation. The NBC 2025 requires regular testing and maintenance records for all emergency lighting and exit signage. Failure to maintain these systems can lead to significant liability issues and failed fire marshal inspections in the London region.
