HazMat Reference

HazMat Reference indexes hazardous-material entries and reference tables for offline educational lookup.

Our take

Consider only as a secondary reference checked against current official sources

Name/UN searching and filters organize a large technical catalogue.

Keep in mind: Placards, exposure figures and regulatory editions are not independently validated; sampled reviewer disputes zone labels. Not an emergency/compliance authority or substitute for trained procedures.

Review themes: 3 US App Store written reviews, updated Mar 9, 2026–Jul 3, 2026. Collected Nov 5, 2026.

Review sources & grouping details

These themes use the completed local review collection and Codex analysis: the latest accessible written reviews within one year, up to 500 per app. This is an accessible sample, not a guarantee of all reviews or a measure of all users.

The feed does not identify each review’s platform. Its date is an update timestamp and may reflect an edited review. Versions shown belong to individual reviews; reported limitations are not verified current-version behavior.

Codex grouped explicit opinions from the review text, with original-text evidence retained. Counts use distinct review IDs, independently of star rating. A review may appear in several topics. The three most-mentioned topics per side are shown first; where more are available, expand the list to see every topic supported by at least three reviews. Group summaries describe recurring aspects across the group; individual examples retain their own context and do not stand in for the whole group. 0 reviews were too general, unclear or off-topic to assign a specific theme. Example summaries are paraphrases; the labeled excerpts are original review text. Analysis updated Nov 10, 2026.
