🔐 Commercial Warehouse Exit Door Requirements – Quebec (Important Code Information)

In commercial warehouses and storage buildings in Quebec, life safety and emergency egress rules are strictly regulated under the Quebec Construction Code (Code de construction du Québec – Chapitre I, Building) and the National Building Code of Canada (NBC) as adopted in Quebec.

One of the most important principles in all occupancy classifications is this:

🚪 Exit doors must allow free and immediate egress

For warehouse or storage occupancies with a low occupant load (for example less than 60 persons), the building code may allow simplified exit door hardware depending on the layout and use of the space.

However, regardless of occupancy size, the key legal principle remains:

A door that serves as a required means of egress must be openable from the inside without keys, tools, or special knowledge.

🔧 Storeroom Function – Acceptable Locking Method

For many warehouse, storage, and non-public commercial spaces, the correct and commonly used hardware is:

👉 Storeroom function lever or cylinder

• Outside handle is always locked
• Inside handle is always free egress (always open to exit)
• Entry from outside requires a key at all times
• No push button, no privacy lock, no deadbolt controlling inside exit

This configuration is widely used in:

• Storage rooms
• Warehouse offices
• Mechanical rooms
• Restricted access commercial areas

It ensures security while maintaining full compliance with emergency exit requirements.

⚠️ Exit Devices vs. Standard Handles

In general:

• Panic bars / exit devices are required when occupant load and public access demand fast evacuation.
• In smaller controlled warehouses (often under 60 occupants and not public-facing), a simple lever handle with storeroom function may be acceptable, depending on final code interpretation and building classification.

However:

• Any modification that prevents instant exit from the inside is prohibited
• Adding locks, bolts, chains, or secondary locking devices on the egress side is not allowed

🔥 Important Fire & Safety Reminder

Even in low-occupancy industrial or warehouse spaces:

• Exit doors must remain operable at all times while occupied
• No special knowledge or action should be required to exit
• Doors must comply with fire safety and inspection authority requirements

📌 Final Note (Very Important)

Building interpretation can vary depending on:

• Occupancy classification (S-1, S-2, F-2, etc.)
• Occupant load calculation
• Local fire inspector interpretation
• Building permits and approved plans
