The correct answer is based on established safety guidelines regarding carbon monoxide exposure. Testing should be stopped immediately at 35 ppm, as this concentration indicates a potentially dangerous level of carbon monoxide in the environment. Exposure to carbon monoxide concentrations at or above this level poses serious health risks, including symptoms like headaches, dizziness, and even life-threatening conditions.

This threshold is supported by standards set by organizations such as the Occupational Safety and Health Administration (OSHA) and the American National Standards Institute (ANSI), which recognize 35 ppm as a maximum safe level for continuous exposure. It is critical to prioritize safety during testing, as high levels can indicate a malfunctioning appliance or improper ventilation conditions that require immediate remedial action.

Understanding this limit is essential for a Quality Control Inspector, as it not only protects the health and safety of individuals during testing but also underscores the importance of taking swift action in potentially hazardous situations. Thus, ceasing testing when carbon monoxide levels reach 35 ppm helps ensure a safe working environment.
