What color indicates a Siamese connection specifically designed for standpipe systems?

In standpipe systems, the color red is specifically designated to indicate a Siamese connection. This color coding is part of the fire protection industry's standards to enhance visibility and recognition of critical fire protection equipment. The Siamese connection, which allows for multiple hose connections to facilitate firefighting efforts, is marked in red to ensure that firefighters can quickly identify and access it during an emergency.

The use of color coding in fire protection systems is essential for swift response and efficiency. Since red is universally associated with fire safety equipment, it ensures that all firefighters, regardless of their training or location, can easily recognize these vital connections.

Other colors, such as orange, purple, or black, may represent different types of connections or equipment within fire protection systems, but red is the established standard for Siamese connections within standpipe systems. This standardization helps maintain consistency and safety during fire emergencies.
