like Jet said buy a smoke hood with CO capabilities.
dust masks does NOT filter CO. and buying goggles is kinda useless if you don't have a good mask ( with's ussually has some kind of eye protection ).
consider buying flashlight's, maybe multi-tool(s) and bottles of water.
that would be a good start. please do some reseach before you start loading up, because that way you will got the best gear for a reseanoble price.
