Which document specifies the depth of cover for underground pipe?

The document that specifies the depth of cover for underground pipe is NFPA 13. This standard provides detailed requirements for the installation of sprinkler systems, including guidelines related to the placement and protection of underground piping.

In the context of underground piping, NFPA 13 addresses how these pipes should be installed to ensure they are safe and functional. Cover depth is critical for preventing damage to the pipes from surface load and environmental factors. NFPA 13 outlines specific requirements for how deep these pipes should be buried to safeguard against potential impacts or disruption, ensuring that the sprinkler system remains effective even under adverse conditions.

Although other documents mentioned, such as NFPA 20, OSHA Standards, and the IBC Code, address various aspects of fire protection, safety, and building construction, they do not specifically detail the requirements for the cover depth of underground pipes as NFPA 13 does. Understanding these standards helps ensure that systems are installed properly and function as intended, contributing to safety and compliance within fire protection systems.
