What should be done if high levels of carbon monoxide are detected in a home?

When high levels of carbon monoxide (CO) are detected in a home, opening windows and ventilating the area is a crucial immediate response. This action helps to dissipate the carbon monoxide concentration, allowing fresh air to enter while reducing the risk of poisoning. CO is a colorless, odorless gas that can be extremely hazardous, and proper ventilation can help in mitigating its effects until further action is taken.

In situations involving CO exposure, ensuring that the air in the home is replenished with fresh oxygen is paramount. While calling emergency services or checking smoke alarms may also be necessary actions to consider, they should follow venting the area as a primary step to ensure safety. Ignoring the presence of CO, especially when associated with an older furnace, poses a significant risk to health, thus emphasizing the importance of immediate action to ventilate the space first.
