Carbon tetrachloride (Ref: ENT 4705)
Last updated: 10/12/2019
(Also known as: tetrachlorocarbon; methane tetrachloride; tetrachloromethane; carbon chloride)

GENERAL INFORMATION
Description
Once used widely as a grain and animal feed fumigant for post-harvest storage either alone or mixed with other substances. Also added to some formulations to aid distribution and to act as a fire suppressant.
