MAINTENANCE OF ELECTRICAL SYSTEMS

      When describing electrical equipment operation and repair, there are two groups of people that may work around electricity. These two groups are called Unqualified and Qualified.

      Unqualified employees: are individuals who face the risk of electrical shock, but are not qualified to make repairs to the electrical equipment. Unqualified employees are generally the people who work in office buildings and laboratory. An Unqualified person could also be a maintenance employee from a non-electrical trade (painter). If you are a Unqualified employee you need to be aware of the following items:

      • There is a risk of severe injury and death associated with contacting energized electrical equipment. People can, and have, died because they were not aware of an electrical hazard in their work area.
      • You should not attempt to repair electrical equipment (extension cords, reset breakers), reach into panel boxes, etc. These tasks must only be done by Qualified Electrical Workers. If you need to have electrical repairs made to your equipment, call the electrical maintenance department.
      • As a Unqualified employee you may see electrical hazard signs and tags that read "Danger Electrical Hazard Authorized Personnel Only". These signs and tags are posted for your safety - stay away from the equipment.
      • If you are an Unqualified person and you are working in an elevated position near overhead lines (roofers), you must position yourself (ladder, boom basket, etc.) so that the longest conductive object you are using (saws, poles, tools, brooms, etc.) cannot come closer than at least 10 feet to any unguarded, energized overhead line.

      On the next page, we will discuss Qualified Employees.
