excavation; contractor's license; safety

HB 2799 amends Arizona's contractor licensing law to enhance safety for workers in excavation projects. It requires contractors whose work includes excavation to ensure the "competent person" (the individual responsible for identifying hazards and taking corrective action) and all employees entering trenches complete and renew trench safety training every two years. The bill also mandates that new license applicants successfully complete a state-approved trench safety training course as part of the licensing process. These changes apply directly to all contractors seeking or renewing a license in Arizona, with the goal of reducing trench-related accidents.
