According to the Bureau of Labor Statistics, in recent years cave-ins have caused an average of 24 worker fatalities and 88 injuries on U.S. worksites. Because excavation and trenching can be technically challenging and carries unique hazards, safe work requires a competent person trained to identify and mitigate these hazards. After completing this course, learners should be able to recognize the hazards of excavations. This microlearning course represents part of a broader topic. For a more complete training experience, see EXC-2.2 Excavation and Trenching - Competent Person.
