Which color is commonly used for the marking of utility lines according to Digsafe?

Utility line markings are essential for safety and helping prevent accidents during excavation activities. The color pink is specifically assigned for marking temporary survey markings, including those used in construction or excavation to indicate the location of utility lines that might be affected by the work being done. This is part of the uniform color code established by Digsafe and other organizations to provide standardization and clarity in the identification of different utilities.

Blue is typically used for potable water, yellow for gas, oil, steam, and communication lines, and red for electric lines. Each of these colors corresponds to specific utilities. The importance of using these colors correctly is to ensure that workers can quickly identify what type of lines they may encounter, promoting safety and reducing the risk of damage or accidents during excavation. Hence, pink's designation for survey markings is pivotal for marking boundaries and points of reference, separate from utility lines.
