On April 28, 1971, Congress passed the Occupational Safety and Health Act to provide all workers a safe and hazard free place to work. This day has since been recognized as Workers' Memorial Day, or International Commemoration Day (ICD). This is now a day of remembrance for workers who have been killed, or suffered work-related disease or injury.
Carbon monoxide (CO) is a colorless, odorless gas that is poisonous and can kill you if you inhale too much.
Every year in the United States, there are about 400 carbon monoxide-related deaths, and about 20,000 people are hospitalized, according to Safeopedia.
