Navigating the 2024 Building Code Compendium is essential for any commercial or mixed-use project. Below, empcontracting.ca Inc. your construction contractor in London, Ontario, breaks down the critical safety and exit requirements under Section 3.10.2.
3.10.2.4. Safety Requirements Within Floor Areas
Section 3.10.2.4 outlines the specific conditions under which standard corridor and fire safety requirements may be modified. Key provisions include:
Corridor and Egress Specifications
- Public Corridor Exemptions: A corridor may not need to be constructed as a public corridor if travel distance from within a rental space to the nearest exit is 15 m or less, provided walls are noncombustible and continuous.
- Sprinklered Buildings: In fully sprinklered buildings, doors in public corridors may not require self-closing devices or latches, depending on travel distance measurements.
- Door Swing Requirements: Egress doors from rental spaces under 50 m² with travel distances under 10 m are not strictly required to swing in the direction of exit travel.
Corridor Widths and Lighting
The width of a corridor is determined by door swing direction: 1,500 mm is required if doors swing into the corridor, while 1,100 mm is acceptable if they do not. Furthermore, all corridors must feature either natural lighting (4% of area) or emergency lighting providing at least 10 lx at floor level.
3.10.2.5. Exit and Service Requirements
Exit Stair and Door Standards
Under Section 3.10.2.5, exit stairs must maintain a clear width of at least 1,100 mm. Similar to floor area requirements, exit doors for small rental spaces (under 50 m²) have flexible vertical axis requirements provided travel distances remain minimal.
3.10.2.6. Service Facilities
All service facilities must comply with Section 3.6 of the Ontario Building Code unless otherwise specified, ensuring that mechanical and electrical systems meet provincial safety benchmarks.
