Fire separation for high-hazard occupancies
The separation required between a high-hazard occupancy and the rest of the building.
A high-hazard occupancy requires separation of a defined fire resistance, and sometimes full physical separation. The requirement follows from the occupancy type and the risk level.
Demonstration scenario
A 640 m² industrial unit adjoining offices
The occupancy
- Occupancy type
- Industry
- Risk level
- Taken from the fire risk assessment in the project
- Unit area
- 640 m²
The building
- Construction type
- —
- Sprinkler protected
- Yes
- Adjacent occupancy
- Offices
- The risk level is determined in the fire risk assessment and is not asked for again here.
- Appendix E of the procedure already sets fire resistance by storey; separation between occupancies is a separate requirement.
