"At empcontracting.ca Inc., we've found that egress hardware is often where London, Ontario builders face the most scrutiny during final inspections. The NBC 2025 focus on 'intuitive operation' means that choosing the right panic bars and lever handles is critical for both safety and passing your occupancy permit on the first try."
Introduction to NBC 2025 Egress Safety Standards
Navigating the National Building Code (NBC) 2025 requires a deep understanding of life safety protocols, particularly regarding egress doors. These regulations are designed to ensure that occupants can exit a building safely and quickly during an emergency. As empcontracting.ca Inc. your construction contractor in London, Ontario, we prioritize these standards to ensure every project is both compliant and secure.
Clear Opening Width and Height Requirements
Under the NBC 2025 updates, egress doors must provide a minimum clear opening width to accommodate the projected occupant load. For most standard exits, a minimum clear width of 800 mm (31.5 inches) is required when the door is open at a 90-degree angle. In barrier-free paths of travel, this requirement typically increases to 900 mm to ensure accessibility for all users.
Direction of Swing and Operational Force
Doors must swing in the direction of exit travel if they serve an occupant load of more than 60 persons or if they lead into an exit enclosure. NBC 2025 also specifies that the force required to open an egress door must not exceed 90 N for swinging doors and 22 N for sliding doors. Ensuring these tolerances are met is a specialty of empcontracting.ca Inc., your construction contractor in London, Ontario.
Latching and Locking Hardware Specifications
The 2025 code emphasizes that egress door hardware must be operable with one hand and without the need for tight grasping, pinching, or twisting of the wrist. For assembly and high-occupancy buildings, panic hardware or fire exit hardware is mandatory. This hardware must be installed at a height between 900 mm and 1100 mm above the floor to remain accessible to all occupants.
Fire Resistance and Self-Closing Devices
Egress doors that serve as part of a fire-rated assembly must be equipped with self-closing devices and positive latching mechanisms. These components ensure that the door returns to its closed position and latches securely after use, maintaining the integrity of the fire separation. Our team at empcontracting.ca Inc. ensures that all fire-rated hardware is ULC listed and compliant with London, Ontario's municipal building standards.
