What color-code is used to indicate fuel piping?

The color code used to indicate fuel piping is red. This identification system is an important safety measure in firefighting and industrial operations, as it allows personnel to quickly recognize the nature of the pipes they are dealing with. Red is specifically designated for flammable liquids, which includes fuel. This visual coding helps prevent mistakes during critical situations, such as during a fire or hazardous material incident, where the content of the piping needs to be understood at a glance to ensure proper handling and risk mitigation.

In the context of other colors used for piping, brown is often associated with flammable solids, yellow indicates toxic substances, and blue is typically used for potable water. Each color serves a unique purpose in safety protocols, emphasizing the importance of standardized color codes in maintaining safety in environments like airports.
