Work Requiring Class II Material Specific 8 Hour Asbestos Trained UW Employees

 

 

Maintenance and Repair Procedures for High Voltage Electrical Breakers That Contain Asbestos Materials

 

 

Prior to starting work, fill out a Permit to Work on Asbestos Containing Material and submit it to the Asbestos Coordinator (AC) and EH&S for approval. All Electrical Breakers are to be considered to contain asbestos materials. Have a Competent Person inspect the job and verify that the maintenance or repair operation will not disturb any friable asbestos material. Other than using the University Blanket Permit, regulatory notification is required for removal and disposal of asbestos-containing material if 10 linear feet or 48 square feet or greater is removed. If a Negative Exposure Assessment has been conducted by the Competent Person, some of the requirements for Personal Protective Equipment may be modified if approved by the Competent Person and by the University of Washington Environmental Health and Safety Office.
