Classify Hazardous Materials

Welcome to HMEx Assistant, the #1 best-selling software used by architects, design professionals, facility managers, and fire and building code officials to classify hazardous materials. It uses guidelines found in nfpa 704, and CAS numbers to help you search, then manage chemical inventory for fire and building code compliance.

HMEx Assistant is officially endorsed by the ICC, and has been the industry standard since 1993.


Whether you’re the building architect, facility manager, or code official for a facility that handles hazardous materials, you need to know which chemicals are used, their hazard classifications, and if they’re over or under quantity limits that might require special treatment as a hazardous occupancy.hazardous materials classification

If you’re the architect or facility manager, you have to compile the list of chemicals on-site and understand hazard classifications and control areas to comply with the fire and building code. Like you know how to do all that!

As the fire or building official, you need the materials pre-classified by hazard class and summarized by control area, or you can’t approve the building plans or operating permits… resulting in project and possibly operating delays. Beyond that, you need a way to validate the hazard classes assigned and control area analysis submitted


Most architects and facility managers either have to learn the code requirements and how to classify the chemicals—or, they have to hire a pricy consultant.

And code officials, with limited time and resources, either minimally validate hazard classes and control area analyses which drives the occupancy classification and the fire and life safe controls installed, or they simply accept the information submitted.

Every part of the process is a struggle without a detailed chemical database that includes the unique hazard classifications used by the fire and building code for EVERY single item in the database—and it’s seldom found on websites or in product safety data sheets.

If lucky, you may find a database—only to discover it is grossly incomplete.

The Big Question

So how do you automate chemical classification and inventory summary reporting and increase your chances of plan approval – at a price within reach?

Maybe you should consider….


#1 Best-Selling Fire and Building code-compliant chemical classification and inventory management.

HMEx is the ONLY system to combine an online chemical database with a chemical inventory management system to classify chemicals, create Hazardous Materials Inventory Statements (HMIS) and Summary Reports, and automatically evaluate compliance with IFC/IBC quantity limits.


HMEx was initially developed in the early ‘90s and has been used by thousands as the industry’s only chemical database for classifying hazardous materials for fire and building code applications–available from the International Code Council (ICC).

Now it’s cloud-based, updated, and includes a modern chemical inventory manager—as the industry’s #1 best-selling classification tool.

Best Solution for Classifying & Managing Hazardous Materials

There are five main reasons to consider HMEx

  1. One of the BEST chemical databases
  2. Offers the BEST chemical classification
  3. BEST chemical inventory management
  4. Absolute BEST Reporting
  5. STRONGEST industry Security

Plus, it is the Price Performance Leader.

Let’s consider each of these reasons in detail.

1) One of the BEST chemical databases

Unlike manual research that can literally take hours if not days, or grossly incomplete existing databases, HMEx gives you access to critical fire and life safety data for thousands of chemicals in one place, allowing you to validate chemical information in minutes, not hours. Features include:

Physical and chemical properties

Displays boiling point, melting point, flash point, autoignition temperature, LD50, LC50, LFL, UFL, molecular weight, specific gravity/density, vapor density and vapor pressure. Having critical data you need to evaluate the potential hazards of a material consolidated in one place saves time.

Regulatory limits for Hazardous Materials

Provides threshold limits and reporting quantities for federal regulatory programs including, SARA, CERCLA, CAA, and OSHA PSM. Having a heads up whether any of these federal programs regulate a material helps you avoid potential fines and penalties for failing to comply.

nfpa 704 cas numberDOT shipping information

Listed and correlated with 49 CFR Hazardous Materials Table 172.101. Easy access to up-to-date DOT shipping names and hazard class information can help keep you in compliance.

Firefighter hazardous materials warning placards

HMEx uses IFC Appendix F based on guidelines found in NFPA 704, Standard System for Identification of the Hazards of Materials for Emergency Response, to develop and display hazard ratings needed to alert emergency responders and comply with building signage requirements. This minimizes the need to look through individual safety data sheets, and it helps make certain the ratings are in the right place on NFPA 704 placards.

Screen chemical incompatibilities

Methodology developed by FEMA/DOT/EPA allows you to screen the consequences of the inadvertent mixing of two materials. This helps avoid catastrophes caused by mixing incompatibles and provides the peace of mind knowing that you did.

2) Offers the BEST chemical classification for hazardous materials

Unlike most chemical databases that do NOT include fire and building code hazard classifications, a simple search in HMEx ensures materials are properly and consistently classified for code compliance.hazardous materials nfpa

IBC/IFC compatible classifications

Contains over 3,400 chemicals and 9,000 synonyms with hazard classifications correlated to the International Fire Code (IFC) and International Building Code (IBC). Saves you time and money and increases consistency across jurisdictions.

Identifies additional hazards for NFPA and OSHA

Identifies hazard classifications beyond the IFC and IBC, including irritant, sensitizer, carcinogen, radioactive, and other health hazards. Knowing more about a material’s health hazards assists you with the implementation of NFPA 704 and OSHA’s hazard communication system.

3) BEST Chemical Inventory Management of Hazardous Materials

Most generic chemical inventory management software is not designed for chemical classification of hazardous materials for fire and building code compliance. In contrast, HMEx empowers you to classify, create and keep your inventory in compliance with the latest fire and building code in a fraction of the time, and have more accuracy.

Empowers you to manage, classify, create and update your own chemical inventories and generate summary reports with a single system – minimizing the need for costly consultants.

Auto-populates Inventory Statement

Automatically populates your inventory statement with fire and building code hazard classes and NFPA 704 hazard ratings for chemicals found in the database. Saves time and money, reduces mistakes.

Automatically Evaluates Inventory

Compares inventory quantities with limits set by the code, automatically applies the quantity increases and decreases allowed based on the fire protection controls and location, and notifies you if they’re over. Ensures accurate results, saves time, and reduces errors.

Data Exchange with External System

Import and export inventory data to and from external sources. Saves you time, minimizes manual data entry, and reduces errors.

Manage by Facility, Site, and Building

Simplifies managing inventories at complex sites. Users create and maintain inventories by company, site, facility, building, floor, and control area. Ensures consistency, adds organization, reduces mistakes, and simplifies updating where inventories are maintained by multiple users. All of which encourage more frequent inventory updates and increases compliance.

4) Absolute BEST reporting

Instead of spreadsheets that require complex formulas, extensive formatting and often still lack all the information needed for approval, HMEx automatically creates Inventory Statements and Summary Reports that demonstrate competence and compliance, making it a breeze for code officials to review and approve submittals.

Standardized Hazardous Materials Inventory Statements (HMIS)

Inventory Statements display essential information for each chemical, including the amount confined to cabinets and whether it’s contained in a pressurized system. Increases confidence that necessary variables have been considered and included in the summary and allowable quantity calculations. This helps you get quicker plan approval from jurisdictions with HMIS that exceed requirements.

Hazard Class Summary Reports

Formatted to compare actual inventory quantities with maximum quantities allowed for each hazard class. Values that exceed allowable quantities or violate code requirements display red on the Summary Report, making it easy for you to confirm compliance and for code officials to review and approve.

5) Strongest Industry Security

Extensive data security features include SOC 2 compliance, data encryption, firewall-secured operating system, infrastructure redundancy, multi-factor user authentication, data protection daily back-up, and ISO 27001 certification.

These features ensure your chemical inventory and facility data, as well as user and payment information, remain secure and accessible only to authorized users.

Plus, it is the price-performance leader!

HMEx includes the best features for the price. It saves countless frustrating hours calculating maximum allowable quantities and building reports and potentially saving weeks of delays due to incorrect or incomplete classifications.
