What must a trainee do if they fail the rules examination?

When a trainee fails the rules examination, they must cease all CNG related activities. This approach ensures that safety standards are maintained and that the trainee does not engage in any activities that they are not adequately trained for until they have successfully passed the examination. Continuing to perform CNG activities without the necessary knowledge and certification could lead to unsafe situations both for the trainee and others around them. It's crucial that trainees fully understand the regulations and operational guidelines related to the handling and delivery of compressed natural gas to ensure a safe working environment. This pause in activity allows for additional training or study before the trainee attempts to retake the examination.
