I am stupid about airborne hazzards as well
I just finished spraying in the shop with an unventilated make shift spray booth of cardboard and no 3M mask or canister respirator.
I did put the air filter machine on and ran it for an hour after I would be done.
Hey, it will just be a quick spray, I will be ok. I do the same stupidity woodworking.
Things that don't kill us immediately are deemed ok...smoking, excessive drinking, drugs, fumes, sunburns.
Cancer is a slow growing process often caused by repetitive irritations/ exposures that force changes to skin cells.
If it developed on the first exposure to something we would freak out and avoid the activity and ban it all together.
Thanks for the reminder, will try to be more careful, especially when my kids around
