about the guy that smokes on oxygen in my bldg

my apt manager is on vacation right now and the person thats over him took over a couple of days, i guess its his manager, since my manager was too busy moving people to the new apt bldg he wouldnt deal with the guy smoking on oxygen so i told his manager that was covering for him, he said in some places its an immediate eviction and that hes also seen this lady blow up cause of oxygen, i think hes dealing with it but im not allowed to know the results of it cause its confidential, anyways, i went to throw out some trash right now and he was screaming at me cause he said i snitched on him, wondered how he knew it was me, dont think they would tell him, he said i shouldve talked to him about it instead, i just told him i didnt want to talk to him, now hes mad at me for it, i dont think the manager told him, he probably just guessed, it wouldnt have done any good to talk to him cause he'll do whatever he wants to do anyways. do you think he got evicted? how do i deal with him in the meantime, not in the mood to get yelled at. i know i did the right thing cause i was talking to someone that would listen. any ideas of how to avoid him, hes outside all the time i need to throw out trash and id like to do it without getting yelled at
