Highly Toxic: a gas that has a LC 50 in air of 200 ppm or less. [2] NFPA 704: Materials that, under emergency conditions, can cause serious or permanent injury are given a Health Hazard rating of 3. Their acute inhalation toxicity corresponds to those vapors or gases having LC 50 values greater than 1,000 ppm but less than or equal to 3,000 ppm ...
Vinegar is made of acetic acid and water, and when you mix bleach with an acid, this forms chlorine gas, Dr. Kelly Johnson-Arbor, a medical toxicology physician and interim executive director at ...
