OBC Part 3: Spatial Separation Requirements | Ontario Building Code Webinar

Navigating spatial separation requirements under the Ontario Building Code (OBC) can be one of the most challenging aspects of designing Part 3 buildings. Decisions related to limiting distance, unprotected openings, and exterior wall assemblies have a direct impact on life safety, code compliance, project costs, and overall building design. In this recorded webinar, Vortex Fire Consulting's Jack Keays (Principal, MSc (Fire Safety Engineering), P.Eng.) and Oprite Bobmanuel (Team Lead, MSc (Fire Safety Engineering), RHFAC Professional, P.Eng.) provide a practical, step-by-step overview of OBC Part 3 spatial separation requirements. Using real-world examples and industry insights, they explain how to interpret code requirements, complete the OBC Data Matrix, and optimize exterior wall designs while maintaining compliance. Whether you're designing a new building, reviewing plans, or looking to strengthen your understanding of the Ontario Building Code, this webinar offers valuable guidance for professionals involved in building design and code compliance.
