Who must supervise individuals performing CNG activities?

The correct answer emphasizes that individuals performing CNG activities must have supervision from their employer. This supervision is crucial for ensuring that safety protocols and operational procedures are properly followed, as CNG activities can involve complex procedures and safety hazards. Employers are responsible for training and overseeing their staff to ensure compliance with regulatory standards and safety measures that protect both the workers and the public.

In contrast, peers may not have the necessary authority or expertise to provide adequate oversight, potentially compromising safety. A government official typically does not engage in day-to-day supervision but rather focuses on regulatory compliance and inspections. Allowing individuals to work independently without supervision could lead to unsafe practices or accidents, which underscores the importance of having an employer oversee CNG activities.
