Piping Systems Labeling and Color Coding Checklist

This checklist supports compliance with AFI 91-203 for safety color coding, labeling, and marking of piping systems. It covers evaluating locations, minimizing markings, applying correct color codes, identifying hazardous materials, addressing secondary hazards with warning colors, and confirming methods of identification. It also prompts supervisors to ensure personnel working with piping systems are trained and that training is documented. Use it to audit facility and utility piping, improve hazard communication, and standardize pipe marking practices across sites.
