Canary in the Coal Mine
Those of us who have had a major mold exposure often become chemically sensitive. We essentially become canaries. We can sense the safety of an environment.
The following is excerpt from an article on bird care. It is a good word to all of us, canary or not.
There is an excellent website called The Canary Report designed to alert us to the hazards of chemicals.Birds have very sensitive respiratory systems, and you will want to avoid using most household cleaners and chemicals around your bird. This includes anything with a strong scent or chemical odor, cleaners, sprays, liquids, aerosols, etc. You should not use air fresheners (deodorizers and scents) when you have a bird, including sprays/aerosols, plug-ins, powders, and scented candles.
