Cal/OSHA Trenching & Excavation Safety

Online Training Certification Course

Title 8 CCR 1540 Article 6

From the highest rated and most trusted online training company - since 2008.

This online training course covers Cal/OSHA regulations for excavation site requirements, the hazards present at excavation sites, protective systems that can be implemented, and requirements for those systems. The excavation safety training also covers employer and employee responsibility for training and implementing necessary safety measures.

The risks of working in trenches and excavations include cave-ins, floods, and other emergencies that can cause entrapment and even death. If an employee understands the risks involved and how to properly guard against them, injuries and fatalities are far less likely to occur.

This course is for:
Trenching and excavations are necessary to maintain and repair underground installations such as power lines, sewer systems, and other utilities. They may also be necessary when constructing a building or repairing a bridge. Any employee who is exposed to these operations needs to be adequately trained regarding the hazards present at the worksite.

Case Study: In California, a plumber was killed when a trench collapsed around him. He had been working for the company only two days when the incident occurred. The worker was dispatched along with a backhoe operator to connect residential and main sewer lines. The backhoe operator dug the trench and deposited the soil at the edge of the excavation. No protective systems were implemented, but the company indicated that typical excavations of this kind were sloped to prevent cave-ins instead of dug sharply out like this particular trench. The victim jumped into the trench to continue digging with a shovel when the walls caved in. The sharp angle of the trench walls combined with the fact that this area had previously been excavated was enough to cause the trench walls to collapse, burying the victim completely. Despite rescue attempts by coworkers and paramedics, the victim was pronounced dead at the scene due to asphyxia.

Key Takeaway: While the company had a training program in place, it failed to ensure that its employees completed the program before being dispatched to a potentially hazardous work site. Because the victim had only been employed by the company for two days, he had not yet had the time or opportunity to complete necessary training. Had he undergone proper training, he may have recognized the hazardous situation and avoided the incident. It is unknown whether the backhoe operator underwent satisfactory training for this task.

It will take a MINIMUM of 2 hours to complete this online course. The student may log on and off as needed. A bookmark will be set so when they log back in they will return to where they left off.

We have no restrictions on how long a person takes to complete a course. Likewise, if you are purchasing for others, we have no time limit on assigning courses. So you can purchase a larger quantity than you currently need and take advantage of volume discounts.

Employers are responsible for training new personnel before assigning them to tasks that may expose them to hazardous worksites. Additionally, recurrent training is needed whenever new hazards are introduced into employees' work areas. This online certification meets this requirement.

Each student will receive 0.2 CEUs (or 2 CMEs) from Compliance Training Online® for completing this course.
