Sarah's Expert Insight
OBC Compliance Specialist
"When planning seasonal venues in London or Muskoka, many clients overlook that air-supported structures require a 1-hour fire separation and full building sprinklers if attached to existing facilities. At empcontracting.ca Inc. your construction contractor in London, Ontario, we emphasize that early spatial planning is critical to meet the 3-meter property line setback and avoid costly site plan revisions."
Navigating the 2024 Ontario Building Code (OBC) is essential for safe and legal temporary installations. Whether you are erecting event tents or industrial air-supported structures, understanding Part 3 requirements ensures your project remains compliant and safe for the public. At empcontracting.ca Inc. your construction contractor in London, Ontario, we specialize in implementing these complex safety standards.
Firefighting Access and Electrical Safety for Tents
3.14.1.9. Firefighting Access
Every tent installation must provide clear access for firefighting personnel. This ensures that emergency services can respond effectively to any incident without obstruction.
3.14.1.10. Electrical Systems and Public Safety
To mitigate fire and shock hazards, all electrical systems—including fuses and switches—must be inaccessible to the public. Furthermore, any cables running along the ground must be protected by trenches or heavy-duty covers to prevent damage from pedestrian or vehicular traffic.
Regulations for Air-Supported Structures
3.14.2.2. Occupancy Restrictions and Interior Construction
Air-supported structures are subject to specific occupancy limitations. They cannot be used for Group B (Care/Treatment), Group C (Residential), or Group F, Division 1 (High-hazard industrial) occupancies, nor can they serve as classrooms. While interior walls and mezzanines are permitted, any interior construction must adhere to stringent fire safety requirements found in Articles 3.2.2.20. to 3.2.2.93.
Spatial Separation and Property Safety
3.14.2.3. Minimum Distance Requirements
Standard regulations require air-supported structures to be located at least 3 meters from other structures and property lines. However, exceptions exist for structures not occupied by the public, provided no hazard is created. If an air-supported structure is attached to a permanent building, that building must be fully sprinklered and separated by a fire-resistance rating of at least 1 hour.
