What is the approved size for the lettering on the "SAFE WATER" tags for potable water lines?

1/4 inches
3/8 inches
1/2 inches
7/16 inches

The correct answer is: 1/2 inches

The approved size for the lettering on "SAFE WATER" tags for potable water lines is 1/2 inches. This specification ensures that the tags are sufficiently legible and easily identified by everyone, including those who may not be familiar with the plumbing system. Proper labeling is crucial for safety and compliance with regulations, as it helps prevent contamination of potable water supply and ensures that anyone working on or around the water lines is aware of their nature. This standard reflects best practices in plumbing safety, highlighting the importance of clear communication regarding the quality of the water in the pipes. The other choices do not meet the standard size required for visibility and clarity, which is why they are not correct for this specific application.
