How HMEx handles MAQ compliance

Know where you stand against maximum allowable quantities (MAQs)

HMEx compares your chemical inventory against MAQ limits in real time – so you can see where quantities are within limits and where they exceed code thresholds.

Evaluate MAQs by control area and occupancy
Quantities are automatically compared based on control area, occupancy classification, and storage or use conditions.

Account for real-world conditions
Apply adjustments for fire protection systems, storage configurations, and other factors that impact allowable quantities.

Aggregate quantities by hazard class
HMEx groups materials by hazard class and evaluates totals the way the code requires – so results align with IFC and IBC expectations.

Identify exceedances immediately
The Summary Report highlights where limits are exceeded, so you can take action or adjust design before submittal.

Built for how MAQs are actually applied

MAQ compliance isn’t just a calculation – it depends on how materials are classified, stored, and grouped. HMEx connects classification, inventory, and MAQ evaluation in one workflow so results are consistent and defensible.

Why teams choose HMEx

Code-aligned Hazard Classification
Use a consistent, defensible process aligned with fire and building codes.

Quantity Threshold Analysis
Automatically compare quantities to MAQs and control area limits.

New in HMEx!

Classify directly from SDS data

Enter SDS data or GHS hazard classes, and HMEx Assistant will:

Cross-reference GHS hazards to fire and building code hazard categories
Prompt for any additional information needed
Recommend IFC/IBC hazard classes for review

This reduces manual classification time and helps you make decisions using current product-level hazard data.

5 Reasons to Consider HMEx

hazard classes

1. A Best-in-Class Chemical Intelligence Engine

Say goodbye to fragmented spreadsheets and incomplete databases. HMEx Assistant centralizes thousands of chemical records with validated fire, health, and regulatory data — built for real-time compliance, not academic curiosity.

✔ Physical & Chemical Properties
Quickly access boiling points, flash points, autoignition temps, vapor pressures, LFL/UFL, LD₅₀ values, and more — all in one place. Save time classifying, placarding, or evaluating thermal and flammable risk.

✔ Built-In Regulatory Thresholds
Automatically flags reporting thresholds for programs like SARA, CERCLA, CAA, and OSHA PSM, helping you stay ahead of federal regulations and avoid noncompliance penalties.

✔ DOT Shipping & Hazard Classification
Directly correlated to 49 CFR Table 172.101, HMEx provides up-to-date shipping names, UN numbers, and hazard classes — streamlining your transport compliance and SDS checks.

✔ NFPA 704 & Placarding Logic
HMEx uses IFC Appendix F and NFPA 704 standards to auto-calculate and place hazard ratings for first responders and inspectors — no more hunting through outdated SDSs.

✔ Screen for Chemical Incompatibilities
Using FEMA/DOT/EPA methodologies, easily detect dangerous chemical pairings that may require separation, engineering controls, or mitigation — with just a few clicks.

2. World-Class Hazard Classification

Other tools stop at CAS numbers — HMEx goes further. We classify chemicals for code compliance across multiple frameworks: IFC, IBC, NFPA, and others

✔ IBC/IFC-Aligned Hazard Classes
Over 3,400 chemicals and 9,000 synonyms mapped to fire and building code classifications — ready for permitting, plan check, and MAQ calculations.

✔ SDS to IFC Mapping
Transfer relevant GHS hazard class data from an SDS to generate IFC code-aligned classifications in seconds.

3. Built for Modern Inventory Management

Unlike generic systems, HMEx is built for hazardous materials from the ground up — with MAQ logic, control area support, and NFPA 704 data embedded in every entry.

✔ In-House Inventory Control
Create, classify, and manage chemical inventories at the facility, floor, and control area level. Empower your team to keep data current and submission-ready.

✔ Auto-Populated Inventory Statements
Instantly generate accurate inventories with hazard classes, NFPA 704 ratings, storage type flags, and more — cutting weeks off your permitting timeline.

✔ MAQ Compliance in Real Time
Compare actual inventory quantities against MAQ limits with auto-adjustments for fire protection controls and storage conditions — always up-to-date, always code-aligned.

✔ Integrate with External Systems
Import/export from Excel, CSV, or API — connect your inventory to your ERP, EHS, or facility dashboards with minimal IT overhead.

✔ Manage by Site, Facility, or Floor
Support large campuses and multi-tenant buildings with inventory views filtered by site, company, control area, or user group — purpose-built for operational clarity.
