This app serves as a quick reference and educational tool for employees that are involved with the regular handling and storage or incident response of Hazardous Materials.

Materials from the Hazardous Material Table (HMT) and Emergency Response Guidebook (ERG) are listed in easy to review form with advanced search, sort, and filter capabilities. Pertinent information from the HMT, ERG, NIOSH and other sources are listed with the proper placard and hazard class for each material.

The Hazardous Materials Table (HMT) 49 CFR §172.101 is a list of hazardous materials by proper shipping name that governs the transportation, marking and labeling by all modes: air, water, rail, and highway. Understanding and knowing how to use information in the HMT is the first step toward compliance.

The Emergency Response Guidebook (ERG) is primarily a guide to aid first responders in quickly identifying the specific or generic hazards of the material(s) involved in the incident, and protecting themselves and the general public during the initial response phase of the incident. The ERG is updated and released every 4 years by the D.O.T.

Quick and very user friendly

An exact copy of the book. Very quick to open for information and easier than carrying the book!

Hazmat Must!

Very quick and easy to use reference. My favorite part of the app is the ability to quickly see the amount of hazmat allowed on cargo and passenger aircraft.
