Excavation and trenching are among the most hazardous construction operations. Cave-ins pose the greatest risk and are much more likely than other excavation-related accidents to result in worker fatalities. The United States Bureau of Labor Statistics (BLS) data show that 271 workers died in trenching or excavation cave-ins from 2000 through 2006. In addition to cave-ins, workers may also be exposed to the risks associated with combustible gases and oxygen deficiencies during trenching operations. Other potential hazards include falls, falling loads, and incidents involving mobile equipment. All of these hazards are recognized and preventable, yet injuries and fatalities related to trench work and excavation continue to occur.

In this course, you will learn how to protect employees against trench cave-ins and other hazardous conditions. You will also learn what you must do to comply with the Occupational Safety and Health Administration (OSHA) Excavation and Trenching standard, Title 29 of the Code of Federal Regulation (CFR), Part 1926.650. This course is relevant to business owners, engineers, managers, foreman, and any other personnel working in industries that require excavation and trenching operations.
