Mission
Chiller Short-Cycling
The chilled water plant serving the process hall is tripping on low pressure, restarting, and tripping again — about twelve times an hour since first thing this morning. Chilled water flow temperature is climbing and two process lines will have to come off if it reaches 12 °C. The contract refrigeration engineer can be on site in four hours and wants to know whether to bring gas.

You can call it at any point. Submitting ends the mission and is scored on the evidence behind the answer, not only on the answer.
