ERG Table 2: Water-Reactive Materials which Produce Toxic-By-Inhalation Gases

When spilled in water, large amounts of Hydrogen chloride (HCl), Sulfur dioxide (SO2) and Hydrogen sulfide (H2S) may be produced.

Hazmat Table (49 CFR 172.101)

The Hazmat Table in 49 CFR 172.101 "lists and classifies those materials which the Department (of Transportation) has designated as hazardous materials for purposes of transportation".

UN/NA datasheets display several items from the Hazmat Table: proper shipping names, hazard classes and divisions (explosives may also include a compatibility group letter), label codes, and special notes relating to shipping location, shipping name, and whether the material is an inhalation hazard.

Descriptive text for each label code is shown below the table, along with representative vehicle placards.

UN/NA Proper Shipping Name Hazard Class Labels Notes*

* There are three notes: (1) whether the displayed information is for domestic (U.S.) or international shipping (if neither is specifically indicated, it applies to both), (2) whether the proper shipping name must include one or more technical names of the hazardous material in parentheses, and (3) whether the hazardous material is an inhalation hazard.
