Refrigeration systems shall be operated and maintained according to which code?

Building
Fire
Uniform Mechanical
Life Safety

The correct answer is: Uniform Mechanical

Refrigeration systems are primarily governed by the Uniform Mechanical Code (UMC). This code outlines the standards for the installation, maintenance, and operation of mechanical systems, including refrigeration. It ensures that these systems are designed and maintained safely and effectively, meeting specific performance and safety requirements. The UMC provides regulations that help ensure the proper functioning of refrigeration systems, addressing aspects such as construction, energy efficiency, and safety measures to prevent issues like refrigerant leaks. Compliance with this code helps maintain the integrity of the refrigeration system, promotes energy efficiency, and enhances the safety of the working environment. Other codes mentioned do not specifically focus on the operation and maintenance of refrigeration systems. The Building Code typically addresses the structural and architectural aspects of buildings. The Fire Code is concentrated on fire prevention and safety measures, while the Life Safety Code is centered around ensuring the safety of occupants in emergency situations. None of these codes provide the comprehensive guidance on mechanical systems that is found in the Uniform Mechanical Code.
