Course Description

Trenching and Excavating: Hazards involving excavations and trenches, can lead to serious incidents involving workers at construction sites. Workers can be critically injured or die in cave-ins. Many cave-ins occur on small jobs of short duration, such as water, gas, electrical and sewer line connections. Employers, supervisors and workers must follow the requirements set out in the Occupational Health and Safety Act (OHSA) and Regulations for Construction Projects.  The course is designed to provide participants with an awareness of Federal and State requirement, covering practical considerations for safe and compliant excavation and trenching. This portion of the course will include the following:

  • WAC (Washington Administrative Code) 296-155-PART N
  • General Protection Requirements
  • Requirements for Protective Systems
  • Soil Classifications
  • Sloping and Benching
  • Timber Shoring
  • Aluminum Hydraulic Shoring
  • Selection of Protective Systems
  • Fall Protection Requirements
  • Stability of Adjacent Structures
  • Daily Inspection Requirements
  • Written Test

Confined Space Awareness Training: Many workplaces contain areas that are considered “confined spaces” because while they are not necessarily designed for people, they are large enough for workers to enter and perform certain jobs. A confined space also has limited or restricted means for entry or exit and is not designed for continuous occupancy. Confined spaces include, but are not limited to, tanks, vessels, silos, storage bins, hoppers, vaults, pits, manholes, tunnels, equipment housings, ductwork, pipelines, etc. Class participants will learn how to identify these spaces, and what controls must be implemented prior to entry including:

  • Training Requirements
  • Confined Space Hazards
  • Space Classification
  • Air Monitoring (4-gas meters)
  • Forced Air Ventilation
  • Postings
  • Controlling Access
  • Emergency Rescue Requirements
  • Duties of Attendant and Space Supervisor
  • Permit Process


Each student will receive a wallet certification card for both Trenching & Excavation and Confined Space Awareness. These certifications are valid for 2 years each.
