Is it possible to have doors on the fire wall between Class C vehicle areas and the adjacent Class A areas, where there is a 5% gap?

Thread Content

For Class C vehicle spaces: “Is it possible to install doors on the fire wall between two Class A areas where the distance is less than 5%?” The interpretation of clause 3.1.2 of the Building Code states that fire and explosion prevention separation measures should be used to \"completely separate\" Class A production areas from other areas. Question: 1. What are fire and explosion prevention separation measures? The blast wall should be included; should the floor slabs be included as well? 2. Complete separation: Does installing fire doors and vestibules in an explosion-proof wall constitute complete separation? 3. Should the evacuation be calculated based on Class C workshops, or does this portion need to be calculated separately for evacuation purposes under Class A?
