The consequences are significant as the falling earth can bury or crush any person in its path resulting in death by suffocation or internal crush injuries. The speed of an excavation collapse increases the risk associated with this type of work. Prevent people and materials falling in – with barriers strong enough not to collapse if someone falls against them.Įxcavation failures are particularly dangerous because they may occur quickly, limiting the ability of workers (and in some cases others nearby) to escape, especially if the collapse is extensive.Do not assume ground will stand unsupported.
