Soil trenching is extensively used in geotechnical, mining, tunneling and geo-environmental infrastructure activities. Since soil trenching involves excavation work in limited spaces, soil trench failures can directly result in loss of lives. Although several provinces in Canada published guidebooks to emphasize occupational health and safety concerns related to fatalities associated with trench failures, a large number of worker deaths are still reported each year associated with soil trench failure.

土壤挖沟广泛用于岩土工程、采矿、隧道和地质环境基础设施活动。由于土槽开挖涉及有限空间内的挖掘工作，土槽故障可直接导致生命损失。尽管加拿大的几个省出版了指南，强调与沟渠故障相关的死亡相关的职业健康和安全问题，但每年仍有大量工人死亡与土壤沟渠故障有关。
