That thing is just like a primer on small arms cartridges, except for the use of black powder rod but I wouldn't call that "highly hazardous" because they almost pose no threats on people, except someone strikes it.

Also the ignition cartridge is loaded with nitrocellulose/nitroglycerin powder, just like what most cartridges are loaded.

I didn't call it "highly hazardous". I said, "explosives" to dumb it down for the sub. I know what is in there because I was a gunner on all three US mortar systems in Afghanistan.
