ERG Table 2: Water-Reactive Materials which Produce Toxic-By-Inhalation Gases
When spilled in water, large amounts of Hydrogen chloride (HCl) may be produced.
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.
