Understanding OBC Part 3: Combustible Elements and Noncombustible Construction
Navigating the 2024 Building Code Compendium is essential for successful commercial and residential developments. As empcontracting.ca Inc. your construction contractor in London, Ontario, we prioritize compliance with Section 3.1.5 to ensure safety and efficiency in every build.
3.1.5.16. Combustible Elements in Partitions
The Ontario Building Code allows for certain combustible elements, such as solid lumber partitions (min. 38 mm thick) and wood framing, within noncombustible buildings. These are permitted in floor areas not exceeding 600 m² that are not sprinklered, provided they are not required fire separations and are not located in high-risk occupancies like care facilities or detention centers.
3.1.5.17. Storage Lockers in Residential Buildings
In residential buildings required to be of noncombustible construction, wood storage lockers are generally permitted in storage rooms, offering a practical solution for multi-unit residential projects, excluding retirement homes.
3.1.5.18. & 3.1.5.19. Combustible Ducts and Piping Materials
Combustible ducts and piping are subject to strict flame-spread and smoke-developed ratings. Generally:
- Ducts: Combustible ducts are permitted primarily in horizontal runs and must meet Subsection 3.6.5 requirements.
- Piping: Combustible piping and adhesives must maintain a flame-spread rating of 25 or less, and a smoke-developed classification of 50 or less in specific high-rise buildings.
- Sprinklers: Combustible sprinkler piping is permitted within sprinklered floor areas, facilitating modern fire suppression designs.
