What is the accepted distance for parking apparatus during a trench collapse?

The accepted distance for parking apparatus during a trench collapse is 100 feet. This distance is recommended to ensure the safety of the personnel and equipment in the event of further collapse or instability. It allows for a safe working area for responding crews, minimizing the risks associated with a trench collapse, such as additional ground subsidence or falling debris. Setting the apparatus at this distance provides sufficient buffer space for operations and protects firefighters from potential hazards related to the affected trench. This safety standard helps to ensure that both the firefighters and any victims involved can be safely approached and managed without increasing the risk of additional collapses that could endanger more lives.
