- Load suggestions (Beta) (Load suggestions): New planning tool for 49 CFR §177.848 — optimized load groups for hazard-class segregation and for Class 1 compatibility groups. Available from the menu and as a preview on the segregation check page (registered users see diagrams and restriction details).
- Restrictions in load suggestions: Conditional (yellow) segregation notes — including class 9 pairs — are listed again in the Restrictions column with expandable detail text.
- Load group diagram: Each suggestion row now labels load groups clearly (Load group 1, Load group 2, …) with stronger spacing and borders between groups.
Updates to HazMat Tool, regulatory data releases, and site improvements.
Latest News
- Substance information (info search): Each entry now opens with an At a glance summary (UN/ID, hazard class, packing group, ERG guide, special provisions) and an HMT snapshot badge showing the active §172.101 table month. On phones and tablets, a Jump to section menu replaces the desktop section bar. Navigation labels are in English; Copy link and Print / PDF are available (print layout hides ads and menus).
- Search: Substance name / UN autosuggest on the info search and related fields — dropdown stays open while you move the pointer to a suggestion.
- Segregation workflow: On Add Hazardous Material, a Segregation check quick button appears once you have two items. The segregation check page offers a clearer layout and a printable report (new window → Print → Save as PDF). Labels are consistent: Segregation check (U.S. HMR) vs. Compatibility check (TRGS).
- Help & legal: Updated Help (scope and disclaimer), Feedback (clearer form and topic categories), Imprint, and Privacy with current operator contact details.
- PWA: Install HazMat Tool on your home screen (Add to Home Screen) with a simple offline fallback page.
- Behind the scenes: Cleaner XML/JSON responses from the substance database API; quieter server logs for special-provision lookups and cache misses.
- Dataset update: The HMR Hazardous Materials Table (49 CFR §172.101) has been rebuilt from the current eCFR release. The active table contains 3,687 rows (approximately 3,005 entries with UN/NA/ID numbers plus alphabetical cross-references). Where entries could be matched to the previous table generation, ERG guide numbers and CAS references were carried forward.
- Regulatory deltas you will notice in daily use include revised special provisions (column 7), updated vessel stowage codes in column (10B)—for example additional stowage categories for certain Class 8 materials—and new or restructured proper shipping names (including “Articles containing …, n.o.s.” and corrosive aerosols under UN1950). Multi–packing group listings (PG I / II / III) for a single proper shipping name are stored as separate rows, as in prior HazMatTool releases.
- Compatibility checks, substance information, special-provision lookup, and search all use the updated table. If you rely on a specific UN entry for compliance documentation, verify critical rows against the official §172.101 text or your company’s dangerous goods procedures.
