In order to make room in my garage, I needed to move my 6' x 4' Gorilla Rack down into my basement. Is it safe (health wise) to store chemicals in the basement -- as long as they are all sealed? I already stored paint and oil down there for years. I'm not worried about my waxes/polishes/etc, but what about pesticides and weed killers? All OPE gas is stored in outside storage shed. Maybe I'm just paranoid, but I want to keep my family safe. Of course the HVAC is in the basement -- along with gas water heater. The rack is stored well away from any heat source (different room in finished basement). I guess they are all stored indoors in stores, so it shouldn't be any different in our basement?
