A colorless, oily liquid that causes eyes to water. Chloropicrin is a highly toxic irritant used in tear gas, dyes, disinfectants, and insecticides. It has also been used as a wood preservative. Trace amounts of chloropicrin are added to odorless fumigants (Methyl bromide, Sulfuryl fluoride) to act as a warning agent. However, unless the air is dry, chloropicrin may corrode metals.
