A tear gas canister found near Tahrir. Photo by @ghadasha
This canister is clearly marked “MK II 570 CS”, one can also read that its produced by “Federal laboratories”
As this is outdated by far, it will be diffiult to find any online description of this product.
Though we will try anyway.
This might be the same product as this one – 37mm short-range spede-heat
In which case, there is a – MSDS *Though keep in mind that the canister used is very outdated.
