Overview
The workshop explains the hazards of excavation and trenching, how accidents happen, and how worker protective measures should be applied. It’s a great way to inform new employees of safety protocol or to update more experienced employees on new safety information.
The workshop covers:
- Critical definitions and context for excavation safety
- Soils analysis: testing local soils and handling testing equipment
- Shoring options: a walk-through of all the basic systems—sloping, shoring, and shielding
The workshop also provides assurance that all relevant duties of a competent person at an excavation site will be fully covered and explained. However, the employer has responsibility and authority to actually designate a worker as a Competent Person. The course covers the requirements of 29 CFR Part 1926, Subpart P-Excavations, of the OSHA standards for the construction industry and essential material on the similarities and differences between General Industry Confined Space and the new Construction Confined Space standard Subpart AA.
Participants must be present for all 3 days to receive their certificate and wallet card.
