In trench rescue operations, how far should the first in company spot their apparatus away from the location of trench failure?

In trench rescue operations, it is critical to position emergency apparatus at a safe distance from the trench failure to ensure the safety of the responding personnel as well as to avoid additional hazards. Spotting the apparatus 150 feet away allows for sufficient space to minimize risks associated with potential secondary collapses, which may occur when crews approach the site of the initial failure. This distance also provides a buffer zone for personnel to operate safely without being in the immediate danger zone of falling earth or other hazards that could arise during rescues. Additionally, having the apparatus positioned further back allows for easier access and egress routes for both personnel and equipment, as well as preventing the risk of being directly impacted by any additional excavation or shifting soil. Proper positioning is fundamental in trench rescue operations, ensuring that all team members can perform their tasks effectively and safely.
