Committee Statement

CommitteeStatement:

NFPA 400 is the expert document on maximum allowable quantities and the requirements for hazardous materials. Now that NFPA 400 is an established document, NFPA 5000 is able to extract applicable provisions regarding hazardous materials. All MAQ tables should be extracted from NFPA 400 for this edition of NFPA 5000 and those going forward.
