The underlying color rules for markings, identification and operational warning in fire safety are very important to users, operators, auditors, and system maintenance engineers or technicians. This does not only help in systems documentation, but also tracing and working on the correct piping routes during maintenance, upgrade, and ease in systems process automation and control. NFPA 704 – Standard System for the Identification of the Hazards of Materials for Emergency Response, ANSI/ASME A13.1 – Pipe Color Code Standards, ISO 14726 – Color Coding Piping Systems, and ISO 22324 – Societal Security – Emergency Management – Guidelines for Color-Coded Alerts are the benchmarking standards for compliance on color codes. ISO 20471:2016 Amendment – High Visibility Clothing makes provisions for safety wear with regards to requirements for high visibility clothing. ‘NFPA 1950 – Standard on Protective Clothing, Ensembles, and Equipment for Technical Rescue Incidents, Emergency Medical Operations, and Wildland Firefighting, and Urban Interface Firefighting’ gives guidelines on the aspect of protective clothing, including hard hats or safety helmets. American National Standards Institute / International Safety Equipment Association ANSI /ISEA 107-2020 – Standard for High-Visibility Safety Apparel, and The Occupational Safety Health Administration (OSHA) covers aspects of color for safety wears. OSHA has color standards for caution and barricade tapes too. Guidelines for helmets are given in ISO 2925 – Specification for Industrial Safety Helmets, and Construction Skills Certification Scheme (CSCS).
