This procedure is used for equipment that cannot be effectively covered under a two point Lockout Procedure. Multipoint procedures are used where more than two locks are required or for convenience due to frequency of use. Multipoint Procedures are recorded using the Multipoint Lockout Procedure Form. The procedure must be checked and approved by the supervisor or instructor prior to implementation.
- All Procedure Forms must have the identifying number of the locksets and the number of locks in the set prior to use recorded on the Procedure Form.
- The name of the worker is printed in the space provided under the heading on the first page.
- The worker will use the lock out sheet for direction and apply locks to each point as required by the procedure. At each point, the worker will initial the corresponding point on the lock out procedure form.
- If any point on the procedure is deemed to be not applicable under the circumstances, the letters “N.A.” (Not Applicable) must be written by the entry and the reason should be stated on the sheet. Should additional points be required, they must be written in ink and initialled by the worker.
- Locked out equipment must be checked to insure it will not run prior to isolating the block valves or lock points. The isolation of the equipment will now be completed.
- Then place the keys for the lockset in the key box on the Lock out Board and seal1 the box closed. The seal* number must be recorded on the Procedure form.
- When the lock out is complete and prior to commencement of work, the worker will review the lock out points with supervisor to ensure all lock out points are secure and that the supervisor is advised of any abnormalities.
- The worker and the supervisor will then sign the Procedure Form to indicate lock out is complete and attach the procedure to the designated Lock out Board.
- The equipment is now ready for work to commence. Personal locks are applied.
- Each worker or contractor required to work on the equipment must lock the key box with his or her own personal safety lock before commencing work. NO ONE IS TO PLACE THEIR PERSONAL LOCK ON THE BOX IF THE SEAL* IS NOT INTACT.
- If the seal1 must be broken all personal locks must be removed (to test a motor, for example). The number of the replacement seal must be inserted on the procedure and the reason for the replacement written on and signed by the original worker and supervisor that approved the initial process.
- Should the seal1 be broken, missing, or if the seal number does not correspond with the number on the Procedure Form, the Procedure Form must be removed and the Multi point lock out must be re done from the beginning.
- All locked out devices must be checked by the supervisor and where practicable the originating worker that initiated the first lockout to ensure the lock out points are secure before the key box is resealed and work on the equipment is permitted to resume.
- Prior to reenergizing the equipment driver, insure the isolation points are in the ready state.
- After all work has been completed and the personal locks have been removed from the Key Box, the device operator will remove the Procedure Form and break the seal to the Key Box. The device operator will now remove the Lock Set Keys from the Lockout Board to prevent anyone from entering or starting work on the equipment while it is being unlocked. They will check to ensure that the equipment is ready for operation.
Personal Safety Locks must be removed when the work on the equipment has been completed. If the work is theoretical in the classroom environment removal is at the discretion of the instructor in charge of the exercise.
