Alphabetical directory of every material in the ERG 2024 Blue Pages. Browse by first letter or digit to find UN numbers, response guides, and TIH designations for over 3,000 hazardous materials.
The full 49 CFR §173 hazard-class taxonomy: Explosives, Gases, Flammable Liquids, Flammable Solids, Oxidizers, Toxic, Radioactive, Corrosive, and Miscellaneous. Definitions, hazards, public safety response, packing groups, and common UN numbers.
Full text of the special-provision codes referenced by column 7 of the §172.101 Hazardous Materials Table: numeric, A (aircraft), B (bulk), IB/IP (IBCs), N (non-bulk), T (portable tanks), TP (portable-tank special), and W (water) codes.
The nine Globally Harmonized System (GHS) pictograms found on workplace and container labels, with hazards described and mapped to their equivalent DOT transport classes.
Decide the UN number, packing instruction, section, and required marks/labels/documents for a lithium battery shipment. Covers Li-ion and Li-metal, standalone / packed-with / contained-in-equipment, ground and air (passenger + CAO), with hard stops for damaged, disposal, and prototype batteries.
Convert a battery spec sheet (voltage × capacity) into Wh per cell and per battery, plus a g-Li estimate for Li-metal cells. Feeds the Lithium Battery Decision Tree.
How many lithium cells or batteries fit in one package under §173.185(c) / IATA PI 965–970 Section II — with per-package net-mass caps and per-consignment restrictions by mode.
Pick the right UN entry for a battery-powered vehicle, equipment, or cargo transport unit — UN3171 vs UN3536 vs UN3556 / UN3557 / UN3558. Handles item type × chemistry, calls out the alternatives it ruled out, and lists the applicable rules.
Visual reference guide for the 49 CFR §172 hazard placards. Click any placard to view active UN listings.
A single "DANGEROUS" placard may substitute for two or more Table 2 placards when the load carries at least two different hazard classes and less than 5,000 lb aggregate gross weight of any one class from one facility.
Orange "CARGO AIRCRAFT ONLY" label required on any package that exceeds the passenger-aircraft quantity limit in column 9A but is within the cargo-aircraft limit in column 9B. Such packages may only travel on cargo aircraft.
Bulk packagings and tank containers that once held hazardous materials must continue to display the original placards until they are cleaned, purged, or refilled. The Empty / Residue label communicates that a container still contains residue of the previous cargo.
Generate a DOT-compliant hazardous materials shipping paper. Enter shipper, consignee, and packages — UN number auto-fills class, packing group, ERG guide, and labels from the UN database. Live preview, one-click PDF export.
Interactive 49 CFR §177.848 segregation chart. Pick any two hazard classes to see whether they may be loaded, transported, or stored together, plus the Class 1 explosives compatibility table and the §177.848(c) additional segregation requirements.
Plan a mixed hazmat load across the fewest trucks that still comply with 49 CFR §177.848 segregation. Enter each package with its hazard class, weight, and volume; the planner partitions items into compatibility groups and bin-packs each group by First-Fit-Decreasing against the chosen equipment capacity.
Paste a shipping-paper UN list and get an instant compliance report: HMT verification, §177.848 segregation cross-check, §172.504 placard requirements per hazard class, and marine-pollutant / reportable-quantity flags. Inverse of the Load Planner — you already know how the load is packed; this tool checks whether it is legal to release.

ERG 2024 Green Table 1 — initial isolation and downwind protective action distances for TIH and water-reactive materials, by UN number, spill size, and time of day.
Estimate fireball radius, emergency response distance, and evacuation distance for an LPG tank at risk of a boiling-liquid expanding-vapor explosion. Interpolates between the ERG 2024 BLEVE table rows.
Mandatory evacuation and preferred shelter-in-place distances for suspected improvised explosive devices (IEDs) and outdoor LPG tanks, per ERG 2024.
Every isotope listed in 49 CFR §172.101 Appendix A Table 2 with its Reportable Quantity in curies (Ci) and terabecquerels (TBq). Cross-reference for the Class 7 packaging UNs (UN2908–UN3332), which classify the package type, not the isotope inside it — the RQ that triggers §171.15 discharge notification is looked up here per radionuclide.
