In this table, the substances are listed in numerical order of their 4-digit ID numbers.
The ID number is followed by the 3-digit guide number and the name of material.
An icon in the columns WRM, CWA and TIH indicates that the product is either, a water reactive material, a chemical warfare agent or a toxic inhalation hazard.
If the 3-digit guide number is supplemented with the letter "P", it indicates that the material may undergo violent polymerization if subjected to heat or contamination.
For entries highlighted in green follow these steps:
NOTE: If the name in Table 1 is shown with "When Spilled In Water", these materials produce large amounts of Toxic Inhalation Hazard (TIH) gases when spilled in water. Some Water Reactive materials are also TIH materials themselves (e.g., Bromine trifluoride (1746), Thionyl chloride (1836), etc.). In these instances, two entries are provided in Table 1 for land-based and water-based spills. If the Water Reactive material is not a TIH and this material is not spilled in water, Table 1 and Table 2 do not apply and safety distances will be found within the appropriate orange guide.
