What is the minimum required temperature for a pump room?

The minimum required temperature for a pump room is set to ensure that all equipment operates correctly and efficiently, particularly in environments where freezing could create significant issues. A temperature above 40 degrees Fahrenheit is considered necessary to prevent any liquid within the pump system from freezing, as freezing can lead to damage in the pumps and associated piping.

Keeping the temperature above this threshold helps ensure that the pumps and other mechanical components remain in good working order and can perform their intended functions without risk of ice formation, which could impede operation or even cause significant system failures. This temperature guideline is critical in maintaining the integrity and reliability of fire protection systems, where pumps play a vital role in water supply during emergencies.

Higher temperature thresholds, like those proposed in the other options, could indeed provide more safety margin against freezing, but the established minimum requirement recognizes 40 degrees as sufficient for operational purposes in most climates.
