Course Content
- A trench can bury a worker in seconds
- By the end of this course, you'll be able to:
- Ground collapse gives almost no warning
- The soil around a buried worker is astonishingly heavy
- You do not need a deep trench to die in one
- Excavation work brings several deadly hazards together
- Undisturbed ground is holding back enormous force
- A handful of conditions turn a stable trench into a trap
- Loads and water near the edge push the walls in
- Previously dug ground is more dangerous, not less
- Never rely on 'being careful' near an unsupported wall
- A competent person decides how the trench is protected
- Four proven ways protect people from the walls
- Battering slopes the walls back; shoring holds them in place
- How to work safely around a protected trench
- Every dig risks hitting a service you cannot see
- Different buried services fail in different, dangerous ways
- Before You Dig Australia is free, and lodging an enquiry is step one
- Safe digging follows a plan, locate, expose, then dig sequence
- Not all location information is equally reliable
- Rules for working near live services vary by state
- A trench deeper than 1.5 m is 'high risk construction work'
- The business must find and share service information before digging
- Excavation controls go well beyond the trench walls
- The worker in the trench cannot see what is coming at them
- An excavation can become a confined space with unsafe air
- If the trench collapses, do not jump in to dig them out
- Who regulates excavation work where you work
- Now make the calls on a real dig
- On site: a stormwater trench across the yard
- The essentials to carry onto every dig
