## Description

HazMat Reference (ERG 2024) is your quick offline tool for hazardous materials, combining HMT, ERG, CFR/NIOSH data for employees involved in handling, storage, or incident response. It aggregates material data from the Hazardous Materials Table (HMT) and Emergency Response Guidebook (ERG), presenting placard and hazard-class details with proper context.

Key features include advanced search, sort, and filter capabilities; offline access; search by name or UN Identifier; NFPA Fire Diamond visuals; CAS and RTECS numbers with NIOSH IDLH and exposure information; quicksort by UN ID, guide number, name, or incident count; and access to all ERG tables and reference pages. You can also filter materials with DOT-reported incidents in the last 12 months and view material histories (most viewed or most recent).

## Review summary

Users widely praise HazMat Reference as a handy, fast, portable quick-reference for toxic materials and emergency response. It’s repeatedly described as invaluable to safety professionals, easier to use in the field, and a strong alternative to carrying bulky books. However, several reviews highlight UI/readability issues, noting very dark color schemes that hinder reading and a non-ideal interface that could improve for larger screens. Overall, the app is viewed positively for timely information access with room for interface improvements.

### Pros

- Handy and fast quick-reference for HazMat information; invaluable for safety professionals and emergency responders.
- Replaces multiple reference books; easily accessible at your fingertips and faster than the book.
- Easy to use and user-friendly; many reviewers describe it as perfect or great.
- Broad applicability across roles (hazmat responders, chemical tanker drivers, firefighters, pipelines).

### Cons

- UI/readability issues: distance pages are very dark, making text hard to read; interface not consistently user-friendly and could benefit from improvements for larger screens.
