H/T to my moots here who have been screaming into the void to raise awareness of this issue, and so I’m going to boost it.
ICE is using hexachloroethane gas grenades. There can be used as smoke markers. When used as riot control, it is inexcusable. Here’s why:
HC gas is a potent central nervous system depressant. It also causes cancer. It will absorb through your eyes, respiratory tract, and importantly, your skin!
Is the green colour from Cl₂ gas, another compound, or a combination?
"Chlorine gas ... was first used as a weapon in World War I by Germany on 22 April 1915, in the Second Battle of Ypres.
...
Chlorine reacts with water in the mucosa of the lungs to form hydrochloric acid, destructive to living tissue and potentially lethal."
I've suffered chlorine gas poisoning. Teacher didn't know what a gas jar lid was and supplied none for the forty gas jars. Un-nice.
@zl2tod the colors are from various dyes, most of which are bad for you. Unclear what is in the formulation out there at the moment but…
THE MAJOR dye components of the smoke formulation are benzanthrone (BZA) (54% of the dye components) and dibenzochrysenedione (DBC) (38%) (Lundy and Eaton 1994). DBC is also referred to as vat yellow 4. In the old M18 grenades, the colored dyes are mixed with a pyrotechnic mixture containing sulfur, potassium chlorate, and sodium bicarbonate. Optional amounts of a mixture of pure, refined kerosene and tricalcium phosphate are added for control of dusting and caking, respectively.
