What hand wheel color is used for potable water?

The color used for hand wheels associated with potable water systems is dark blue. This color coding is an industry standard designed to identify and differentiate various types of water supplies and associated systems. Dark blue is specifically designated for potable water to ensure that it can be quickly and easily recognized by personnel in various contexts, such as plant operations or emergency situations.

This color coding system enhances safety by preventing cross-contamination with non-potable water systems, enabling operators and maintenance staff to efficiently locate and manage water supply controls. The use of standardized colors helps streamline operations and limit confusion, particularly in facilities where multiple systems may be in close proximity. Other color options you might see are designated for different types of systems, reinforcing the importance of using the correct color to maintain clear identifiers for each utility type.
