This orientation will be required annually and if necessary repeated if new information and/or work location changes. This orientation does not address all procedural items that a Chelan County PUD employee overseeing a project would typically review with the contractor.

Contractors are responsible for reviewing checklist information and procedures with their employees. This checklist is not designed to cover every safety issue applicable to Contractors’ work. Contractors are responsible for observing and educating their employees with regard to any and all safety regulations, procedures and equipment requirements applicable to employment in general, as well as those specifically applicable to their type of work. The Contractor is solely responsible for the safety of the Contractor’s employees and the work site.

Route original document or electronic copy once completed to the Safety/HR Dept. Admin.



Initials are required in each section by staff providing the orientation. (If section(s) do not apply, write N/A.)
