Lower explosive limit for acetone
WebFor example, the lower explosive limit for acetone is 2.5 percent acetone in air (about 25,000 parts per million), however workers can experience health effects such as irritation and intoxication at concentrations of 1,000 parts per million. Flammable gases such as carbon monoxide and hydrogen sulphide are toxic at very low concentrations.
