In the last week there have now been several posts in which an OP is clearly distressed. Buried deep in their rants (and in previous posts in other subs) were actually a few details that were easily missed. I had already been drafting my concerns at length and will post that in the first comment on this post. Most everything in the comment is superfluous and just me desperately trying to connect with them. The two big points I'd like reviewed would be the links.

I am not a CIH. I'm revisiting his issue, and posting separately for two reasons:

1. I think this is a potentially severe ventilation issue compounded by improper construction, cleaning & PPE measures in an enclosed space rather than the intentional chemical poisoning OP fears. OP's current state is hiding the important bits.
2. My family currently faces a residential issue that also includes hazardous exposure concerns. So, before I get to that I'm posting this first in order to differentiate our situations and my own approach to this kind of problem from OP's before asking for advice. I'd like to avoid our own questions getting dismissed as repetitive at best or paranoid at worst.
