What should be the height of letters on a safe water tag?

The correct height for letters on a safe water tag is 7/16 inch. This specification ensures that the text is large enough to be easily readable from a distance, which is critical for safety and compliance purposes. The purpose of a safe water tag is to convey important information about water safety to individuals who may be handling or using the water, making visibility and legibility paramount.

Using this size allows for clear communication in a variety of settings, helping to prevent misunderstandings that could lead to unsafe practices. Adhering to the established standards helps maintain consistency in safety procedures across installations, ensuring that everyone recognizes and understands the warning represented by the tag.
