2018 IMC warehouse ventilation rates

[HVACQuestions]

For the IMC 2018 warehouse ventilation rates, they specity 0.06 cfm/sf, which has been the standard. but now they've added a 10 cfm/person requirement, which is new, but the occupant density column is blank. so how do i establish a minimum ventilation rate?

Figure out the occupancy per IBC TABLE 1004.5
MAXIMUM FLOOR AREA ALLOWANCES PER OCCUPANT
500 gross SF per person for Warehouse
Then figure out your total

Same question posed, same answer provided. Same issue in the '21 code so no help there. IMC commentary has several places that tell us not to use the IBC for density, but it's all we have for now.
