Taking carbon monoxide (CO) readings during the worst-case conditions is essential for accurate assessment of potential hazards and ensuring safety. Worst-case conditions refer to scenarios where the appliance or system operates under the most unfavorable circumstances, often leading to increased emissions. This includes conditions such as a closed environment with limited ventilation, which can cause the worst levels of CO to be present.

By measuring CO levels under these conditions, inspectors can identify the maximum potential for CO buildup, allowing for a better understanding of how well the appliances function and their safety. This practice helps in determining whether the combustion appliances are operating within safe limits and if any adjustments or repairs are needed to mitigate risks associated with CO exposure.

This approach is crucial for ensuring compliance with safety standards and regulations, as it enables inspectors to recommend necessary actions if CO levels exceed acceptable thresholds.
