Fellow fire community. I've run up against a conundrum and I'd like some input by others who either actively support laboratories or had supported them in the past.

Hello-   I am looking for some information regarding the storage amounts of Level 2 and 3 Aerosols in a General Purpose Warehouse. In general I am going by the amounts found in NFPA 30b 6.3.4, specifically a max of 2500 pounds.    My question is are those amounts specific to 50,000 square feet? If I segregated our aerosols in our 100,000 ft… (Show more)
