National Building Code Standards for Industrial Storage and Hazardous Materials

Navigating the complexities of the National Building Code of Canada (NBC) is essential for any industrial development. When ensuring your facility meets these rigorous fire safety and structural standards, empcontracting.ca Inc. your construction contractor in London, Ontario provides the professional expertise required to maintain compliance and safety.

3.3.5.9. Multiple-Tenant Self-Storage Warehouse Requirements

In multiple-tenant self-storage warehouses classified as industrial occupancies, fire safety is paramount. Unless the building is protected by a professional sprinkler system, each individual tenancy must be separated from the rest of the building by a fire separation with a fire-resistance rating of no less than 45 minutes.

3.3.5.10. Standards for Industrial Guards

For industrial occupancies (excluding storage garages), the NBC specifies that guards must be constructed to prevent accidental falls while allowing for functional industrial use. These guards are permitted to consist of:

• A top railing.
• One or more intermediate rails spaced to prevent the passage of a spherical object with a diameter of 535 mm.

3.3.6. Design and Storage for Hazardous Areas

3.3.6.1. Application of Dangerous Goods Standards

This subsection governs the fire protection and design requirements for buildings used for the handling, processing, and storage of dangerous goods, including flammable and combustible liquids, in quantities exceeding those identified in the National Fire Code (NFC).

3.3.6.2. Fire Separations for Dangerous Goods

The NBC mandates strict fire separation protocols for high-risk materials:

• Oxidizers and Organic Peroxides: Must be separated from the remainder of the building by a fire separation with a rating of at least 2 hours.
• Reactive Materials: Require a minimum 2-hour fire-resistance rating for all separations.
• Explosives: Storage design must strictly conform to the “Explosives Act” and Natural Resources Canada regulations.
• Electrical Safety: Any electrical equipment in areas containing flammable gases, vapours, or combustible dust must conform to CSA C22.1, the Canadian Electrical Code, for hazardous locations.

3.3.6.3. Indoor Storage of Compressed and Toxic Gases

Storage of flammable, toxic, or oxidizing gases requires specialized architectural considerations. Flammable gas cylinders must be housed in a room that is:

• Separated by a gas-tight fire separation with a minimum 2-hour rating.
• Positioned on an exterior wall with direct exterior access.
• Equipped with self-closing devices and gas-tight seals to prevent migration of vapours into the building interior.

For toxic or oxidizing gases, the fire-resistance rating requirement is at least 1 hour. Implementing these safety features correctly is vital for facility approval.
