I watched again and what I didn't notice the first time is the little rating box at the bottom. I can tell it says PG-13 but the video is too low quality to read the rest of it.

I've kind of kept out of this because I think the barrel speculation is pretty moot, but a few things from my about the barrel of what is intended to be a serious corrosive of some kind. I deal with pH 2 acid sanitizers and pH 13 basic desoilants at work literally every day.

First, there is definitely some movie magic going on here. While plenty of corrosives are capable of having a reaction that generates heat or bubbles, they are likely not green and not bubbling inherently unless they've been recently diluted from a salt form (most basic corrosive chemicals we use have an exothermic reaction when they get mixed with water for use, the products ship to us as a stable salt (salt meaning the category of chemicals, not table salt literally) either in flake or powdered crystals).

The reason we use these chemicals at my work is for debris removal and sanitation in a beverage industry. I would guess that if the event outside the shelter is some kind of virus/infection/etc. that the barrel scene is about sanitizing or decontaminating something. That's what it looks like to me.

It's pretty unlikely that the chemical would be used to dispose of waste, it would be a waste of that resource when there are natural, self sustaining ways to deal with waste (like fish/algae or composting). Even if you use an acid or a base to corrode something, the base organic material is still in the solution and would, over time, neutralize the pH of the corrosive.

That said, it could be Howard doing something like melting something in the chemical as a matter of dramatic effect or because he's a weirdo, so who knows. Just my two cents on what's likely.

For the record, I without any of that chemical knowledge, had assumed something similar from the first time I saw that barrel in the trailer.

The bit with the green goo actually just confirmed that for me.

I really think it's just a a strong chemical sanitizer of some kind.

Probably because clean water is at a premium in a bunker.

Lego version of the trailer -- very cute!

Here is a crop of that image:

Oxidizers don't necessarily just relate to flammability, most sanitation chemicals are aggressive oxidizers, so don't focus too much on the "combustion" term in there. Many acids are oxidizers.

Oxidation is frequently what yields their sanitary properties. The oxidation of the cell wall of microorganisms causes lysis and that causes cell death.
