What is the requirement for labeling pipes in a medical gas system according to NFPA 99?

In a medical gas system, the requirement for labeling pipes according to NFPA 99 is focused on color coding. This is crucial for ensuring the safety and clarity of medical gas delivery systems within healthcare facilities. Color coding allows for immediate identification of different gases, reducing the risk of errors in gas delivery that could have serious consequences for patient care.

For example, oxygen pipes are typically identified by a specific color, which helps personnel quickly recognize the type of gas being delivered, thereby enhancing operational safety. This standardization is vital in emergency situations where time and accuracy are of the essence.

Color coding serves not only to prevent cross-connections between different gases but also aids in quick identification for routine maintenance and inspection processes. Thus, the correct answer emphasizes the importance of standardized labeling through color coding as mandated by NFPA 99 to uphold safety standards in medical environments.
