What color should the NST hydrant adapter be painted?

The NST hydrant adapter is painted yellow to signify its specific use within the fire department's equipment and operations. This color coding is important because it helps firefighters quickly identify the adapter and differentiate it from other equipment during emergency responses. The choice of yellow serves as a visual cue that enhances safety and efficiency, especially in high-stress situations where time is critical. Understanding this color-coding system is essential for ensuring that all personnel are familiar with the tools they will be using in the field, thereby promoting effective teamwork and response actions.
