I would buy up some of these along with some canisters of R22 refrigerant.

What I am trying to understand though is I read he was in front of the screen in the movie theater with a gas mask on.He threw chemical canisters and people thought this was a stunt for the new movie and that it was fog.The theaters we have here have no way to unlock a door from the outside.You have to push open from the inside to get in next to the screens.So how did this guy get in from what they say a gas mask,chemical canisters,a shot gun,and assault rifle,and two regular size hand guns?????

We also give tenants a canister of disinfectant wipes with their move-in gifts, so they can tend to matters on their own.

Maybe, if the oil canister is an eyesore, isn't secure and easily spilled, you told him he can move it, he needed to move it to use the yard, he told you he was going to move it, etc. 

I have been a tenant and an owner of units with recessed lighting, and changing the bulbs is a huge pain and it's almost impossible to put the canisters back in place.
