GWWI Water Distribution Practice Test

The minimum distance that materials should be kept from the edge of a trench is crucial for maintaining safety on a job site. Keeping materials at least 2 feet away from the trench edge helps prevent the risk of collapse or slide that could occur if materials are stacked too close. This distance allows for adequate space to ensure stability and reduce the likelihood of a potential hazard associated with the trench itself.

Safety regulations and best practices in excavation work recommend this distance to protect workers from the dangers associated with trench collapses and to maintain structural integrity. Therefore, maintaining a minimum distance of 2 feet from the edge is essential for safety while performing excavation activities.
