Course Overview

This comprehensive Excavation and Trenching training course equips participants with essential knowledge and practical skills required for planning safe excavations, identifying soil hazards, and implementing protective systems to prevent cave-ins and other excavation-related hazards. The course covers fundamental excavation safety principles along with practical techniques for soil classification, protective system selection, hazard identification, utility location, and emergency response to enable workers and supervisors to conduct excavation operations safely, comply with regulatory requirements, and prevent excavation incidents.


Participants will learn to apply proven methodologies including Soil Classification procedures, Protective System selection, OSHA Excavation Standards, Competent Person responsibilities, Utility Location protocols, and Hazard Control measures to identify soil types, determine excavation hazards, select appropriate protective systems, inspect excavations daily, and ensure worker protection in and around trenches and excavations. This course combines theoretical concepts with practical applications and real-world case studies to ensure participants gain valuable skills applicable to their professional environment while emphasizing cave-in prevention, hazard awareness, regulatory compliance, and excavation safety culture.
