While I don’t recommend macgyvering things like gas masks, this PDF on How to make an emergency gas mask is better than breathing in methal-ethyl-bad stuff because your mask is in a remote bug out location and not on your side during a terror attack or chemical spill.
I still recommend buying a quality mask and good filters for the people you love, knowing how to make one in a pinch is also good to know.
I like knowing how to do stuff, and I think this PDF is neat, but once again, have I said that it is much better to buy a true mask and filter that is certified against chemical agents than rigging one from soda bottles and household scrap?
If I had nothing else, and I had to get somewhere, and I had no choice but to go through a hazardous chemical plume, I would try this – but it would be my VERY LAST resort, and while its better than taking an unprotected lung full of toxic fumes, a handmade gas mask isn’t that much better….
If you don’t believe me watch videos where your ignorant libs make these and go up against tear gas grenades – they always end up sucking wind and crying….How to Make and Emergency Gas Mask
