"The 2024 OBC updates for rapid transit fire safety highlight the critical need for integrated communication between transit hubs and adjoining commercial developments, which is especially relevant for expanding urban corridors in London and Oakville. As empcontracting.ca Inc. your construction contractor in London, Ontario, we ensure that specialized monitoring systems like CAN/ULC-S561 are seamlessly incorporated into your project to meet these rigorous provincial safety standards."
Understanding Fire Safety Provisions in the 2024 Ontario Building Code
The 2024 Building Code Compendium outlines specific safety requirements for rapid transit stations under Section 3.13.5. These regulations ensure that fire detection, monitoring, and notification systems are integrated and functional within high-traffic public infrastructure.

3.13.5.1 - 3.13.5.2: Fire Alarm Systems and Exceptions
While a fire alarm system conforming to Subsection 3.2.4. is generally required for rapid transit stations, the code provides notable exceptions. Specifically, manual stations and audible signal appliances are not mandatory within the station itself, acknowledging the unique acoustic and operational environment of transit hubs.
3.13.5.3 - 3.13.5.4: Fire Detection and Central Monitoring
In areas where a sprinkler system is not installed, fire detectors must be placed in every service room, ancillary space, leased space, booth, and kiosk. Furthermore, every rapid transit station must be monitored by a central supervising station that conforms to the CAN/ULC-S561 standard, ensuring a direct link to emergency response services.
3.13.5.5 - 3.13.5.6: Annunciator Requirements and Building Integration
Annunciators must be strategically located for easy firefighter access and visible to transit collectors. A critical safety feature in the 2024 code involves adjoining buildings: if an alarm triggers in an adjacent structure within two storeys of a station connection, the station annunciator must flash a warning sign to prevent passengers from using that specific route as an exit.
3.13.4.6: Manual Reactivation of Access Controls
Following a release (often triggered by an alarm), gates, turnstiles, and specific doors must remain in their safety state until they are manually reactivated by an authorized switch. This prevents automated systems from prematurely re-securing an area during an ongoing emergency.
