IMPORTANT SAFETY INFORMATION
1. WHAT IS CARBON MONOXIDE?
Carbon monoxide is a colorless, odorless and tasteless poison gas that can be fatal when inhaled. CO blinds to the hemoglobin in the
blood and inhibits its capacity to carry oxygen. CO kills hundreds of people each year and injures many more because it is difficult to
be detected with the human senses. In high concentrations, CO can kill in minutes.
