Section 9.10.19: Smoke Alarms and Residential Fire Warning Systems
In accordance with the 2024 Ontario Building Code (OBC), maintaining the integrity of fire detection systems is paramount for residential safety. Section 9.10.19.7. dictates that maintenance instructions must be prominently posted for occupants to ensure the continuous performance of smoke alarms.
Advanced Fire Warning Systems (OBC 9.10.19.8.)
For modern builds, residential fire warning systems conforming to CAN/ULC-S540 are permitted as alternatives to standard smoke alarms. At empcontracting.ca Inc. your construction contractor in London, Ontario, we ensure these systems meet all audible signal, power, and silencing criteria required by Article 9.10.19.
Section 9.10.20: Firefighting Access Requirements
Access Panels and Windows (OBC 9.10.20.1.)
To facilitate emergency services, non-sprinklered buildings must provide access panels on the second and third storeys. These openings must be at least 1100 mm high and 550 mm wide. While single-family dwellings and houses with secondary suites are often exempt, professional oversight is necessary to determine compliance for multi-unit projects.
Basement Access Standards (OBC 9.10.20.2.)
Large, non-sprinklered basements exceeding 25m in any dimension require direct outdoor access. This can be achieved via specialized doors, windows, or interior stairs accessible from the exterior, provided they meet the minimum dimension and sill height requirements.
Site Design for Fire Department Access (OBC 9.10.20.3.)
Effective site planning is mandatory for all new constructions. Roadways and yards must be designed to accommodate the weight, width, and overhead clearance of firefighting equipment, including strategic placement of fire hydrants and department connections.
