P-13 Bulk Oil Storage Facility Practice Test

Color coding piping is used to quickly identify the system’s purpose during emergencies. Fire protection piping is painted red because this bright, high-visibility color clearly signals firefighting equipment and lines (like sprinklers, standpipes, and fire pumps). The quick visual cue helps responders locate and operate the fire protection system without delay and reduces the chance of confusion during an incident or maintenance. Keeping this color consistent across the facility, along with proper labeling, ensures everyone can distinguish fire protection lines from other piping. Other colors are typically used for different services (for example, blue for potable water, green for non-potable or other uses), so red best communicates the fire protection function.
