BAY de NOC COMMUNITY COLLEGE PERSONNEL POLICIES AND PROCEDURES
Originator: Board of Trustees Revision Date: Subject: Work Areas 603 Lockout Procedures POLICY The purpose of this procedure is to assure that employees are protected from unintended machine motion or unintended release of energy which could cause injury when they set up, adjust, repair, install or perform maintenance work on equipment, machinery or processes. This procedure applies to all employees performing any of the aforementioned tasks. 603.1 Responsibilities: a. Each supervisor shall train new employees and periodically check to insure that employees know this lockout procedure. If the procedure is not done correctly, retaining is initiated. b. Each supervisor shall effectively enforce compliance of this lockout procedure including the use of corrective disciplinary action where necessary. c. Each supervisor shall assure that the locks and devices required for compliance with the lockout procedure are provided for their employees. d. Prior to setting up, adjusting, repairing, servicing, installing or performing maintenance work on equipment, machinery or processes, the supervisor shall determine and instruct the employees of the steps to be taken to assure they are not exposed to injury due to unintended machine motion or release of energy. 603.2 Employee Responsibility: a. Employees shall comply with the lockout procedure. b. Employees shall consult with their supervisor or other appropriate knowledgeable management personnel whenever there are any questions regarding their protection. c. Employees shall obtain and care for the locks and other devices required to comply with the lockout procedure. 603.3 General: a. The power source shall be locked out by each employee doing work on any equipment, machine or process to be set up, adjusted, repaired, serviced, installed, or maintained to prevent the unintended motion or release of energy, which would cause internal injury. Sources of energy, such as springs, air, hydraulic, and steam shall be evaluated in advance to determine whether to retain or relieve the pressure prior to starting work. b. Safety locks are for the personal protection of the employee and are only to be used for locking out equipment. c. Equipment locks and adapters can be obtained in the departmental supervisor’s office. The sole purpose of the “equipment” lock and adapter is to protect the equipment during periods of time when work has been suspended or interrupted. The locks are not to be used as a substitute for the employee’s personal safety lock. d. Employees shall request assistance from their supervisor if they do not know where or how to lockout equipment. e. Any questions concerning the lockout procedure should be directed to the employee’s supervisor. 603.4 Locking out and Isolating the Power Source: a. Equipment, machines or processes main disconnect switches shall be turned off and locked in the off position only after the electrical power is shut at the point of operation control. Failure to follow this procedure may cause arcing, and possibly an explosion. b. A machine connected to cover a 110 volt source of power by a plug-in cord shall have a locking device applied to the plug attached to the cord leading to the machine to be considered locked out. c. A machine connected to a 110 volt source of power by a plug-in cord shall be considered locked out if the plug is disconnected and tagged with a do not start tag. d. After locking out the power source, the employee shall try the equipment, machine or process controls to ensure no unintended motion will occur or test the equipment, machine or process by use of appropriate test equipment to determine that the energy isolation has been effective. e. When two or more employees work on the same equipment, each is responsible for attaching his/her lock. Safety locks and adapters are to be fixed on levers, switches, valves, etc., in the non-operative (off) position. f. An employee who is assigned to a job and upon arrival finds an “equipment lock,” “adapter,” and “Danger” tag affixed to the equipment shall take the following action: 1. Affix his/her personal lock to the equipment adapter.” 2. Try the controls to ensure no unintended motion will occur before starting work or test the equipment, machine or process by use of appropriate test equipment to determine that the energy isolation has been effective. g. When die or safety blocks are required, they shall be used in conjunction with the lockout steps, not as a substitute. 603.5 Removal of locks and Restoring Power Source a. Power may be turned on when it is required to perform tests or adjustments. All of the rules pertaining to removing locks and restoring power shall be followed. The equipment, or process, shall again be locked out if it is necessary to continue work after completing the test or adjustments. b. If the employee leaves the job before its completion, such as job reassignment or shift change, the employee shall remove his/her personal lock and adapter and replace it with an “equipment” lock and adapter. In addition, the employee will prepare and attach a “danger tag” indicating the reason the equipment is locked out (Should more than one employee be assigned to the job, the last employee removing his/her lock will be responsible for affixing the “equipment” lock, adapter and the “danger tag.”) c. Upon completion of the work, each employee will remove his/her lock, rendering the machine operable when the last lock is removed. d. The employee responsible for removing the last lock, before doing so, shall assure that all guards have been replaced, the equipment, machine or process is cleared for operation, and appropriate personnel notified that power is being restored. This employee is also responsible for removing the “equipment” lock and returning it to the supervisor’s office. 603.6 Emergency Safety Lock Removal: Custodial staff will be authorized to remove an employee’s lock under the following conditions. a. Receipt of a written request signed by the appropriate department supervisor which shall state the reason the employee is not able to remove the lock. b. The supervisor is responsible for making certain all the requirements for restoring power are followed. |
