What system identifies pipes, valves, and equipment by color codes?

The color coding system is specifically designed to identify pipes, valves, and equipment through the use of distinct colors. Each color corresponds to a particular type of substance or hazard associated with the piping systems, providing immediate visual cues to workers about the contents of the pipes and the associated safety measures required.

This system aids in ensuring safety and efficiency in industrial environments by making it easier for employees to recognize and respond to the type of fluid transported within a pipe, whether it is a hazardous material, water, air, or another substance. The use of color codes enhances communication and can significantly reduce the chances of accidents that could arise from misidentifying a system.

In contrast, other options such as the labeling protocol, numbering system, and identification schema do not specifically denote the use of colors to convey information effectively. The labeling protocol might include text-based labels, the numbering system focuses on numeric identifiers, and the identification schema does not inherently indicate a visual color representation used for immediate identification of piping systems.
