Electrical Safety

1. Electrical Safety Hershey Entertainment and Resorts Company Revised 2006 Ref 29 CFR 1910.333

2. Purpose • The purpose of this program is to establish a set of procedures to be followed during work on or near enough to exposed de-energized parts of conductors and electric equipment and to make aware to the employee any electrical hazard they present

3. Lockout/Tagout Procedure • Lockout/Tagout devices shall meet the following specifications: • Durable • Lockout/tagout devices shall be capable of withstanding the environment to which they are exposed for the maximum period of time that exposure is expected • Tagout devices shall be constructed and printed so that exposure to weather conditions or wet and damp locations will not cause the tag to deteriorate or the message on the tag to become illegible

4. Lockout/Tagout Procedure • Durable (cont.) • Tags shall not deteriorate when used in corrosive environments such as areas where acid and alkali chemicals are handled and stored

5. Lockout/Tagout Procedure • Standardized • Lockout and tagout devices shall be standardized within the facility in at least one of the following criteria: • Color • Shape • Size • Tagout: print and format shall be standardized

6. Lockout/Tagout Procedure • Substantial • Lockout devices shall be substantial enough to prevent removal without the use of excessive force or unusual techniques, such as with the use of bolt cutters or other metal cutting tools • Tagout devices, including their means of attachment, shall be substantial enough to prevent inadvertent or accidental removal

7. Lockout/Tagout Procedure • Identifiable • Lockout/Tagout devices shall indicate the identity of the employee applying the device • Tagout devices shall warn against hazardous conditions if the machine or equipment is energized and shall include a legend such as the following: • Do Not Start • Do Not Open • Do Not Close • Do Not Energize • Do Not Operate

10. Procedural Steps to Control Hazardous Energy • Notify all affected employees that servicing of some kind is required on a machine and that it must be shut down prior to lockout to perform service • The employee should have knowledge of the type and magnitude of the energy before shutting down the machine

11. Procedural Steps to Control Hazardous Energy • Before shutdowns or work of any kind can take place, a survey must take place in order to locate and identify all isolating devices to be certain which apply to the equipment to be locked/tagged out. • The machine shall be turned off using the procedures established

12. Procedural Steps to Control Hazardous Energy • If the machine is in operation, it must be shut down by its normal halting procedures • All energy isolating devices that are needed to control the energy to the machine shall be physically located and operated in such a manner as to isolate the machine from the energy source

13. Procedural Steps to Control Hazardous Energy • Prior to starting work on machines that have been locked/tagged out, the employee shall verify that isolation and loss of energy to the machine has been accomplished • Stored energy must be dissipated or retrained by methods such as grounding, repositioning, blocking, bleeding down, etc.

14. Lockout/Tagout Device • Lockout the energy isolating device with assigned individual locks • Lockout devices shall be affixed in a manner as will clearly indicate that will hold the energy isolating devices in a safe or off position • Tagout devices shall be affixed in such a manner as will clearly indicate that the operation of energy isolating devices from the safe or off position is prohibited

15. Lockout/Tagout Device • Where tagout devices are used, the tag attachment shall be fastened at the same point at which the lock would have been • Where a tag cannot be affixed directly to the energy isolating device, the tag shall be located as close as safety possible to the device, in a position that will be immediately obvious to anyone attempting to operate the device

16. Lockout/Tagout Device • Tags are ultimately not as safe as lockout devices, they are merely warnings • The tag should never be removed without permission from the employee/contractor that place it there • Tags must be legible and understandable by all employees

17. Lockout/Tagout Device • Tags, and their means of attachment, must be made of materials that will withstand the environmental conditions encountered in the workplace • Tags may evoke a false sense of security: they will not provide the level of protection that a lock will!

18. Requirement for Testing Lockout/Tagout Effectiveness • Ensure that the equipment is disconnected from the energy source by operating the push button or other normal operating controls • Return the operating controls to neutral of off afterwards • When the machine is locked out, service may begin

19. De-Energizing Equipment • The circuits and equipment to be worked on shall be disconnected from all electric energy sources • Stored electric energy shall be released • Stored non-electrical energy in devices that could re-energize electric circuit parts could not be accidentally energized by the device

20. Application of Locks and Tags • A lock and/or tag shall be placed on each disconnecting means used to de-energize circuits and equipment on which work is to be performed • Each tag shall contain a statement prohibiting unauthorized operation, the disconnecting means and removal of the tag • If a lock cannot be applied, a tag may be used without a lock

21. Application of Locks and Tags • A tag used without a lock shall be supplemented by at least one additional safety measure that provides a level of safety equivalent to that obtained by the use of a lock • A lock may be placed without a tag only: • When one circuit or piece of equipment is de-energized • The lockout period does not extend beyond the work shift • Employees exposed to the hazards associated with re-energizing the circuit or equipment are familiar with this procedure

22. Verification of De-Energized Condition • A qualified person shall operate the equipment controls or otherwise verify that the equipment cannot be restored • A qualified person shall use test equipment to test the circuit elements and electrical parts of equipment to verify that the circuit elements and equipment parts are de-energized

23. Restoring Equipment to Service • The work are shall be inspected: • to ensure that nonessential items have been removed and to ensure that machine or equipment components are operationally intact • to ensure that all employees have been safely positioned or removed • All employees shall be notified that the lockout/tagout devices have been removed

24. Restoring Equipment to Service • The employee who applied the device shall remove each lockout/tagout • Qualified person(s) shall conduct tests and visual inspections to verify that all tools, electrical jumpers, shorts, grounds, and other such devices have been removed

25. Restoring Equipment to Service • If a lock/tag must be removed temporarily: • Clear the machine of tools and materials • Remove employees from the machine or equipment area • Remove the lockout/tagout devices • Energize and proceed with testing or positioning • De-energize all systems and reapply energy control measures to continue the servicing
