Cal/OSHA Trenching and Excavating Safety

Title 8 CCR 1540 Article 6 Online Training & Certification Course

This course has been designed to familiarize employees with the hazards of working in and around an excavation, and to establish an effective understanding of how to avoid and mitigate those hazards. It is important to note that while proper preparation and structuring is one of the most effective ways to minimize risk in an excavation, it is not enough on its own. Without proper training, employees could fail to notice small imperfections in systems or equipment that could lead to serious complications, including cave-ins.

Governing regulations.
Cal/OSHA covers all private sector workplaces, state government, and local government workplaces in the state. Only employees of the federal government and offshore maritime workers are exempted from Cal/OSHA. These workers are covered under the federal OSHA plan.

The federal OSHA standard 29 CFR 1926, Subpart P covers a wide range of regulations related to trenching and excavating. The standard includes preparation for excavation, hazards present in excavations and trenches, and proper safety measures for working in these types of job sites.

Who must take this course?
Excavations are necessary in a wide range of construction, mining, and utility work. They provide access to systems and areas not typically accessible, whether underground or underwater. However, proper precautions must be taken while working within excavations to protect employees and prevent damage to materials, equipment, and subsurface installations. Persons working in these types of environments need adequate safety training to inform them of these risks.

Click to Learn More Course synopsis.

Excavations are necessary to maintain and repair underground installations such as power lines, sewer systems, and other utilities. They may even be necessary when constructing a building or repairing a bridge. However, these types of job sites present hazards for the workers operating in them, carrying the risk of cave-ins, floods, and other emergencies that can cause entrapment and even death. If an employee possesses an understanding of the risks involved, as well as how to properly guard against them, injuries and death are far less likely to occur. In this course, we will talk about how to prepare a site for excavation, the hazards present, protective systems that can be implemented, and requirements for those systems. We will also gain an understanding of employer and employee responsibility for training and implementing necessary safety measures.
