Excavation and trenching work is performed thousands of times daily throughout the United States in all types of conditions. Unfortunately, cave-ins can occur suddenly, without warning, giving little time to react. But their signs are present when proper safety precautions are not taken. This program has been created to increase your awareness and provide you with a better understanding of the laws, regulations, and company safety policies and procedures associated with your work. Ideal learners are workers who may work in or around excavations and trenches.
