Aerosol determinations

2019-11-08 Thread Shawn Chapman via Sprinklerforum
Could anyone assist with determing the level of classification of aerosols per NFPA 30B? I'm trying to determine the total chemical heat of combustion for some aerosol products (8600-13,000 btu)?? Product MSDS sheets don't identify. Thanks in advance.

Are you folks seeing strip malls which are using some IBC code?? that supposedly allows unsprinklered spaces in only certain assembly occupancy lease spaces. For instance, a strip mall that has 2 of 6 spaces only sprinklered with 4 only having feed mains through unsprinklered space? I thought
