Trenching, Excavation and Underground Construction Safety Technician (TET) Independent Study - Construction
Our Trenching, Excavation and Underground Construction Safety Technician certification covers:
- Trenching and Excavation Overview
- Soil Mechanics
- Course Outline
Certification:
Trenching, Excavation and Underground Construction Safety Technician (TET)
Course Objectives:
Excavation, trenching, and underground construction are among the most hazardous construction operations. This course will teach you relative regulatory requirements and safe work practices. The course includes soil mechanics, shoring procedures, sloping and benching, and trench shields. In addition to the hazards of cave in and engulfment the course also covers the other hazards common to this type of construction.
Learning Outcome:
Upon successful completion of this course, the student will be able to identify safety and health concerns, identify regulatory requirements, implement safe work practices, understand soil mechanics and recognize hazards of trenching, excavations and underground construction.
Optional Credits:
The estimated time required to complete the course is 22 hours, but can be done at the student's own pace. The student will take a comprehensive online exam at the end of the course. You must score 80% to receive certification. You have three opportunities to pass the exam.
