What should responders do if CO levels are detected above the normal range?

When carbon monoxide (CO) levels are detected above the normal range, it is crucial for responders to take appropriate action to ensure the safety of individuals in the area. Requesting assistance from the gas company is a necessary step as they have the expertise and resources to address potential risks associated with high CO levels. This might include identifying the source of the CO, evaluating ventilation options, and making sure that gas appliances are functioning correctly and safely.

Addressing this issue promptly is essential because elevated CO levels can pose serious health risks, including poisoning or fatality. The gas company can provide specialized assistance that fire department responders may not be equipped to handle fully.

In contrast, other responses would not adequately ensure safety. Ignoring the readings could put lives at risk, while documenting the findings alone does not address the immediate danger. Evacuating the premises is a significant step but may not be necessary if the gas company can safely mitigate the situation before it becomes critical. Therefore, coordinating with the gas company is the most effective course of action in responding to elevated CO levels.
