finally picked up a couple lbs of calcium hypochlorite to have on hand if needed to make bleach for various reasons to include water treatment. as many warning as i see about it being corrosive and possible out-gassing, im curious as tohow you guys store it? it comes in a plastic bag but it smells like chlorine and i would prefer to be able to store it airtight to keep the fumes and such down. it will be stored in my garage which is detached from my house and not insulated but decently ventilated.

have been thinking of vacuum sealing it? or sealing it in a mason jar but that concerns me wth the oxidizing of the lid... not really sure.

I vacuum-sealed sealed mine in plastic with my Food Saver.

Have you noticed if the bags started to inflate in anyway?

Check out the MSDS here:

I do not think I would seal it up. I would store it in a plastic bucket.

only been about a month but no problems, no bags inflating.

I missed this post originally.

Got a pound of CH and threw in a drawer for, I think, two days. Maybe three. Whoof, big stink. Even though the original still-sealed bag was that super tuff plastic (tyvek?).

Who knows what corrosion it started in my drawer, and I've been airing out the drawer for 4 days now.

I think I'll try to FoodSaver seal mine, too, and keep it in a 2-gallon plastic bucket with lid.

Dang, you do NOT want to store this stuff near anything important. I'm sure it's highly corrosive.
