I looked up the SDS for WD40.

The word "lethal" is associated with the word "aspirant". It also states "Extremely Flammable Aerosol". If you leave it in a closed auto in the summer sun, it can explode. It also states some permissible exposure limits (in mg per kg and g per kg). My wife's experience with it was over 20 years ago, in an industrial setting. She was doing OSHA compliance analysis of a stucco company (home construction industry). To keep the stucco from sticking to all the parts of the building that they didn't want it to stick to (windows, doors, trim, etc.) they were coating those parts with WD40 before spraying or troweling on the stucco. She found that they were way over the PEL, and corrections in their procedures/process were needed.
