Which plumbing code references address health and safety standards?

The choice referencing 520 CMR is appropriate when discussing health and safety standards in plumbing. This section of the code is particularly focused on the regulation of construction and occupancy standards that safeguard public health and safety. It provides crucial guidelines for maintaining sanitary conditions, preventing contamination, and ensuring safe potable water systems.

These regulations are designed with public well-being in mind, addressing aspects such as water quality, system installation, and maintenance practices that potable water systems should follow to minimize health risks. By adhering to these standards, plumbing professionals contribute to the overall safety of community water supplies and the health of the public. Such regulations are essential not only for compliance but also for fostering a safe environment for all users of plumbing systems.

In contrast, the other options may cover various aspects of plumbing work but do not specifically emphasize health and safety standards to the same extent as 520 CMR.
