I am overseeing an NFPA 101, Chapter 43 reconstruction project in an existing storage occupancy that is changing to an industrial/high hazard occupancy.
I am trying to coordinate the means of egress during construction.
Other parts of the building are currently occupied and the new area is less than 50% of the building.
Section 18.104.22.168 requires that the area comply with the applicable new construction chapters of the occupancy. The hazard category per table 43.7.3 leads me to believe this would be a hazard category 1.
The question is: when is the construction area considered to be high hazard?
The contents of the hazardous occupancy will not be present through the entirety of the construction and will only be put in place after the space is ready to be occupied and compliant with all means of egress requirements. During construction, the "high hazard contents room" is just a small room with nothing located inside.
Even with no high hazard contents present until the space is ready to be occupied, does it need to meet the egress requirements of new industrial/high hazard or can it meet the egress requirements of existing for storage?
