i've seen a few Defense Technology Aerosol OC/CS cans recently, all with the hole out the side.
i looked into the OC canisters, and these ones ARE supposed to fire out the side. they are not fueled by metal fires, but by gas. A quick scan on DT's website does not yield oc/cs tho? https://twitter.com/jovannithe1st/status/1297432195468951559

According to Defense Tech, this kind of aerosol can is non-flammable and rated "For indoor use"
It doesn't smoke, it just aerosolizes using pressurized gas,
Interestingly, however, for some reason, the MSDS link for this product is missing from its site
https://www.defense-technology.com/product/oc-vapor-aerosol-grenade/

perhaps that's because when you look at the MSDS you realize this thing is a cancer bomb.
like just take in for a second that they are releasing these in neighborhoods with open windows and they are "suspected of damaging fertility" and "may cause cancer"

so even without the CS added, we KNOW that these are highly toxic gas bomb that will damage the environment, and because OC is involved, this is considered hazardous waste under State-amended federal law https://twitter.com/JuniperLSimonis/status/1297094252858494976

But now let's look at this whole OC/CS combo business. We know that Defense Technology makes combos in various forms but the combo page focuses on sprays not canisters https://www.defense-technology.com/product-category/oc-cs/

And if you go digging you can, in fact, find a product page for the OC/CS Aerosol can listed under canisters, although hilariously, there is an "Inert Vapor" can for its picture. made me miss it more than once!

https://www.defense-technology.com/product/oc-cs-aerosol-grenade/ https://www.defense-technology.com/product-category/canisters/page/2/

And just like the pure OC can, this combo can's page does not have the MSDS link. interesting. this is not normal for Defense Technology product pages, trust me, I've read many.
Good thing they are in an archive Safariland has up here

A look at the MSDS for Product 1050 shows it brings some interesting and fatal products to the game
with consequences for humans and is poisonous to fish (what i'm studying in the long run!!)

And like I know I know I prattle on about regulations, but bbs, this is another avenue along which law enforcement agencies are breaking federal and state mandates as clear as "Do not allow product to reach sewer system."

Because here's the deal, the producers of these hazardous wastes (as defined under OAR 340) are legally responsible to completely remove and transport the solid waste (under 40 CFR 261.2) to proper treatment facility.

https://oregon.public.law/rules/oar_340-102-0011
https://www.law.cornell.edu/cfr/text/40/261.2

This is why they have Department of Transportation hazard classes of Toxic and Corrosive.

If a truck were transporting these munitions and got in an accident, DoT would require a hazmat unit to retrieve the waste.

[sidebar: that's the kind of stuff my dad used to do!!]

Law enforcement regularly and intentionally creates large amounts of hazardous waste and does not take the responsibilities that come along with access to toxic chemicals seriously
This's why I want a moratorium on chemical weapons

https://www.chemicalweaponsresearch.com/moratorium_letter.html

as with the powder balls, with these aerosol cans, and many munitions the agents fire them off with no consideration of impact site -- the first tweet in this thread is from here -- every night, law enforcement gasses neighborhoods.

According to the city's sewer assets map, the grates in the street do in deed do into the general sewer system.

So, given that Section 13 of the MSDS (quoted above) saying users shall "not allow product to reach sewage system"...
I'm wondering what sort of accountability there is for agents using weapons where the product's safety sheet explicitly says not to.
After all,
"The user ...

" has the RESPONSIBILITY to dispose of ... material, residues, and containers in compliance with ... local, state, and federal laws and regulations regarding ... hazardous and nonhazardous wastes. RESIDUALS SHOULD BE TREATED AS HAZARDOUS"
[emphases and oxford commas added]

So again, I call on @OregonDEQ @BESportland
@epa @portlandpolice @dhs_gov @USMarshalsHQ @tedwheeler @ChloeEudalyPDX @JoAnnPDX @AmandaFritzRN @repblumenauer @SenJeffMerkley @RonWyden to do the right thing and put a moratorium on chemical weapons being used domestically.
