How does a facility count the amount of release flammable COI in a mixture that is not a fuel with an NFPA rating of 1, 2, or 3?
If a release-flammable chemical of interest is present in a mixture in a concentration equal to or greater than one percent (1%) by weight of the mixture, and the mixture has an NFPA flammability hazard rating lower than 4 (i.e., NFPA hazard rating of 1, 2, OR 3), and it is not a fuel, the facility need not count the entire weight of the mixture toward the STQ. Mixtures with an NFPA flammability hazard rating of 1, 2 or 3 are calculated by multiplying the perentage of the COI times the total weight of the mixture to see if the amount of the COI is at or above the STQ. If a release-flammable COI is present in a mixture, and the concentration of the chemical is les than one percent (1%) by weight, the facility need not count the COI or mixture in determining whether the facility possesses the STQ.
