This proposed addendum adds a refrigerated warehouse space type to Table 6-1, providing revised ventilation rates for these spaces. These rates include a 'People Outdoor Air Rate, Rp' which will require ventilation during periods of expected occupancy, but do not include an 'Area Outdoor Air Rate, Ra' which will allow the ventilation rate to be zero for refrigerated warehouses with no occupants. Note E to Table 6-1 is modified to indicate that if combustion powered equipment (e.g., a propane forklift) is used in the space, additional ventilation is required.
