Which statement accurately describes the use of carbon monoxide monitors in homes?

The accurate statement regarding the use of carbon monoxide monitors in homes is that they must be located near sleeping areas. This requirement is based on safety considerations, as carbon monoxide (CO) is a colorless, odorless gas that can be particularly dangerous when people are sleeping. Installing monitors close to sleeping areas ensures that occupants are alerted to the presence of CO, allowing for a timely response to avoid serious health risks, including carbon monoxide poisoning, especially when individuals may be less aware or responsive while asleep.

Proper placement of CO monitors enhances their effectiveness, as alerts need to be heard when individuals are most vulnerable. The other options suggest placements or scenarios that would not provide the necessary safety measures; for instance, having monitors only in kitchens or suggesting they are optional with gas appliances overlooks the potential dangers of carbon monoxide exposure throughout the home.
