Excavation/trenching work is inherently dangerous. Prior to starting work at a jobsite, employees must be informed of the potential hazards that may exist in their work environment. In addition to knowing how to recognize hazards, they need to know how to avoid unsafe conditions. OSHA and State safety regulations require employers to train and educate workers to recognize and protect themselves from hazardous conditions. How can an employer expect their people to work safely if they are not aware of what constitutes an unsafe condition and/or what conditions exist?
