When instructed to contact the technical supervisor, what is the best practice to follow?

The correct response emphasizes the importance of timely communication in operational situations involving the Intoxilyzer 9000. Contacting the technical supervisor as soon as possible is crucial in ensuring that any issues or questions regarding the equipment are addressed promptly. By calling from the Intox room, if feasible, it allows for immediate communication regarding the specifics of the situation, which can lead to quicker troubleshooting and resolution of any potential problems.

This practice not only adheres to operational protocols but also underscores the importance of maintaining the integrity of testing processes and ensuring continuity of operations. Immediate communication from the site of the issue offers the supervisor the best context to assist the operator effectively. Other options, while they may provide a means of communication, do not enshrine the same urgency or context required during critical operational moments.
