Excavation and trenching work is performed thousands of times daily, in all types of conditions. Unfortunately, many fatalities and work-related injuries are associated with excavation and trenching incidents. Cave-ins can occur suddenly, without warning, giving you little time to react.

This program has been created to increase your awareness and provide you with a better understanding of the safety procedures associated with your work. Ideal learners are employees who work in or near excavations and trenches.
