What color is fire system piping usually painted with?

Fire system piping is typically painted red to indicate its purpose and ensure visibility. This color coding is a safety standard that helps first responders quickly identify fire protection systems, such as water supply pipelines for fire hoses and sprinkler systems. By using red, it differentiates fire protection infrastructure from other utility pipes, which may be painted in various other colors based on their specific functions, such as water (usually blue), gas (often yellow), or electrical (sometimes green). This standardized approach is crucial in emergency situations, where time is of the essence, and quick recognition can impact response effectiveness and safety.
