Several issues with the Maximum Allowable Quantity (MAQ) tables in Chapter 60 of the 2015 edition of NFPA 1: Fire Code were identified, which led to additional revisions needed in the source document, the 2013 edition of NFPA 400: Hazardous Materials Code . The MAQ tables were subsequently corrected via the issuance of Tentative Interim Amendment (TIA) 1-15-2. In the NFPA standards development process, a TIA is tentative because it hasn't gone through the full consensus process. As such, it will be automatically processed as a Public Input on the upcoming 2018 edition of NFPA 1 (get your Public Input in by July 6, 2015).


Did you know the maximum allowable quantities of hazardous materials specified by the MAQ tables aren't really maximums? Rather, they represent the maximum quantities permitted without providing additional protection measures, known in the Code as Protection Levels. So yes, the MAQs CAN be exceeded, but additional precautions will be required.


Stay safe!
