CARBON TI^TR-lCIiLCRIDE 
Coi.imercially available carbon tetra- 
chloride, (CCI4), is useful as a fumigant in 
the control of insects attacking certain stored 
products such as food stuffs, grains, seeds, 
and fabrics. It may be used alone or in com- 
bination with carbon disulfide or ethylene 
dichloride to reduce the fire hazard of the

after wearing by fumigating them with carbon 
tetrachloride. 
Carbon tetrachloride is a colorless, 
noninflammable liquid heavier than water. It
