This course covers safe work practices for excavation and trenching work. It is meant to be used as an introductory or refresher course for construction workers involved in digging or working in an excavation. It is based on OSHA Construction regulations and industry best practices.

At the end of this module, you will be able to:

  • Describe dangers Associated with trench and excavation work
  • Identify the role of the competent person
  • Identify soil types
  • Describe protective systems (sloping, shielding, and shoring)
  • Identify rules for sloping excavation walls
  • Describe the importance of inspections
  • Identify basic safe work practices

The following key questions are answered in this module:

What are the two exceptions when a system to protect workers from cave-ins is not necessary?
When the excavation is in solid rock and therefore not a risk of caving in, and when an excavation is less than five feet deep AND a competent person has determined there is no risk of a cave-in.

What are the four primary types of soil seen when trenching and excavating, and what are their characteristics?
The four primary categories of soil are: solid rock, which is the most stable of all soils, and has almost no chance of caving in; Type A soil, which is the second-most stable soil type and is made of cohesive clay-like soil; Type B soil, which is less stable as Type A and poses a significant danger of cave-in; and Type C soil, which is the most unstable type of soil which is sandy and granular and comes apart easily.

What methods are used to protect against cave-ins caused by water?
Methods for protecting against water hazards include: special support or shield systems, water removal equipment, and us of a safety harness and lifeline.

Why is extra precaution necessary when excavating an area that has already been excavated in the past?
Pre-excavated earth has looser soil than that of undisturbed soil. This includes soil around buildings and around utility lines.

What is spoil, and how can you reduce the risk associated spoil piles?
Spoil is earth that is dug out of an excavation. To reduce risks associated with spoil piles, they must be either: kept at least two feet away from the edge of the trench, or held back by some type of retaining wall or device.

When should sloping requirements be applied to an excavation site?
When excavations are less than 20 feet deep. Anything deeper than 20 feet must be designed by a registered professional engineer.

What are some hazardous atmospheres commonly seen?
Hazardous atmospheres include: poisonous atmospheres, oxygen deficient atmospheres (less than 19.5% oxygen), combustible atmospheres, and any atmosphere that may cause death, illness, or injury to a person exposed to it.

What underground utilities must be located before digging can begin?
Electric, water, telephone, sewer, and gas lines should all be attempted to located by contacting the local utility owner.

What changes on a site would require it to be re-inspected?
They include but are not limited to: weather changes (rainstorms, thaws, earthquakes, and snowstorms), when fissures, cracks, sloughing, water seepage, or other changes are noticed, and if there is a change in the spoil pile location or size.

Below is a transcript of the video sample provided for this module:

An excavation is any man-made cavity created in the ground by removing earth. A trench is a kind of excavation. It is a narrow channel that is deeper than it is wide. The term trench is typically applied to channels that are less than 15 feet wide at their base. Excavating is one of the most dangerous operations in construction work. There are an average of 70 deaths each year in the US due to excavation accidents and thousands more injuries. Most of these accidents could be prevented by following simple safety procedures. Even if you're not in charge of overseeing an excavation, you should be familiar with the general hazards of this work. Knowing how to spot potential problems will help keep you and your co-workers safe.

Sorry, we're missing some information

How do I log in to watch a video that I have already paid for?

Easy! Moments after you purchase your pay-per-view (PPV) course, you'll receive an email with login details. Just click the link and log in with your user name and password and you're on your way!

I would like to have some of my employees take 5 of your driving related courses, how can i set this up?

We're in the process of making bulk purchases and purchases for multiple users easier. But for now, you can order multiple courses and just let us know who you'd like to assign courses to. With an email for each user, we can set up their training plans and make sure everyone gets the eLearning assignments they need.

How can I get your paper-making courses for free?

Well, we can't blame you for asking... And while we're a for-profit company, there are situations with students and certain educational organizations where we can help out with a selection of eLearning. However, our online courses are extremely economical. And our paper industry courses are in very high demand. So, without knowing more about your situation, we think you'll get loads of value from the $39 you'll spend on any of our premium courses.

Do you have eLearning in Portuguese?

Yes, we do! And in addition to primary English narration, we produce many courses in a growing number of languages, including Spanish, Chinese, Dutch, German, Italian, Japanese, Korean, Polish, Russian, Tamil, and Thai.

I'm unemployed, but I really like your eLearning. Do I get a certificate when I complete a course?

Yes! All of our courses allow you to print a completion certficate upon successfully passing the integrated test at the end of eLearning. In the future, we'll have badges for you to use in your LinkedIn profiles.
