Question 1

What is Maximum Allowable Quantity (MAQ)?

Accepted Answer

Maximum Allowable Quantity (MAQ) is the maximum amount of a hazardous material permitted in a single control area of a building before additional fire code requirements apply. MAQ limits are defined in the California Fire Code (CFC) Table 5003.1.1 and the International Fire Code (IFC), broken down by hazard class (flammable, corrosive, toxic, etc.), physical state (solid, liquid, gas), storage vs. use, and whether the area has sprinkler protection or approved storage cabinets. Exceeding MAQ triggers High-Hazard Group H occupancy classification.

Question 2

What is an HMAR report?

Accepted Answer

A Hazardous Materials Assessment Report (HMAR) is a document submitted to the Authority Having Jurisdiction (AHJ) — typically the fire department — that identifies all hazardous materials stored or used in a facility, classifies them by GHS hazard class, calculates MAQ compliance per control area, and determines whether the facility's hazmat inventory triggers any fire code thresholds. HZMT generates complete HMAR documents from your chemical inventory data.

Question 3

How does automated hazmat classification work?

Accepted Answer

HZMT takes your chemical inventory — CAS numbers, quantities, and storage locations — and automatically assigns GHS hazard classifications using Safety Data Sheet (SDS) data. Each chemical is mapped to its fire code hazard class (flammable liquid, corrosive, oxidizer, etc.), then MAQ compliance is calculated per control area against CFC Table 5003.1.1, including adjustments for sprinkler protection, approved storage cabinets, and floor level. Every classification includes a confidence score.
