 Hey middle schoolers, we need you. Do you want to win a cash prize? Here's what we need you to do. Create your own poster that warns people about the dangers of carbon monoxide, which is also called CO. That's not CO2, like you learned in science class. CO is the invisible killer. You can't see it or smell it. This poisonous gas comes from the chimney or furnace in your home, your parents car, or a portable generator. The Consumer Product Safety Commission knows you have a lot to teach your parents. So join in and teach your parents and other families how to avoid the invisible killer. You can learn more about carbon monoxide here at www.cpsc.gov.co Draw a poster about what you learned about the dangers of CO. Here's how to enter CPSC's CO poster contest.
