What does Part 3 of Division B address?

Part 3 of Division B of the Ontario Building Code specifically addresses the requirements for fire protection and accessibility, which are critical to ensuring the safety and usability of buildings for all occupants. This part sets out standards for fire safety systems, such as alarms, sprinklers, and fire-resistant construction materials, which are essential to protecting life and property during fires. It also includes provisions related to accessibility, ensuring that buildings are designed and constructed to be accessible to individuals with disabilities, in line with the principles of universal design.

The requirements laid out in this part are comprehensive, covering various aspects such as egress (exit pathways), fire separations, and smoke control systems, aimed at minimizing risks and ensuring a safe environment for all occupants. By addressing fire protection and accessibility together, Part 3 emphasizes the importance of considering both safety from fire hazards and equitable access to buildings, underscoring their interconnected roles in the building design and construction process.
