2.9 Lock out and tag out procedure

2.9.1 Purpose and scope

Before performing any preventive maintenance work or service work, a procedure of locking and

tagging must be followed. The procedure, when followed correctly eliminates the possibility of an

employee being injured.

PLEASE NOTE

These procedures represent the minimum lock/tag out requirements. Any additional safeguards

needed to complete work safely can be specified by facilities supervision, the safety officer, the

safety committee and the health department. 2

2.9.2 Description

Whenever it becomes necessary to isolate, control and release energy, the following procedure is

to be followed

(1) Notify affected employees.

(2) Shut down the equipment. Carry out all normal stopping procedures, such as

– depressing the stop button,

– shutting down the station computer,

– switching off the placement system at the main switch.

Fig. 2.9 - 1 Locking the motor contactor

(1) Turn the operating lever counter-clockwise.

(2) Use the screwdriver to push the locking lug out of the operating lever.

(3) Secure the operating lever with a padlock.

– The tag out alternative:

If a machine can be locked out, it must be. However, there are situations where energy iso-

lating devices cannot accommodate locks. In these cases, the energy isolating devices

must be tagged to warn employees that the machine is de-energized for servicing. The tag

must be securely fastened, it must be placed in a position visible to all and it may only be

removed by the person who attached it. 2

(4) Release stored energy

Stored energy in the compressed air supply or electrical energy in electrolytic capacitors must

be released by appropriate means. 2

– After switching off the placement machine wait until the voltages and the compressed air

have discharged (see Sections 2.6

and 2.7), to be able work without any risk.

(5) Verify the lock out.

Testing the lock out can be done simply by pressing the start button. 2

(6) The following steps must be taken to restore the machine to operation.

(7) Check the area. Authorized employees should remove all of their tools and reinstall all

guards.

(8) Notify all affected employees.

Before removing even one lock or tag, inform all workers in the area that the machine is go-

ing to be restarted. 2

(9) Remove locks/tags

Each authorized employee must remove his or her own lock. Each authorized employee will

have his or her own lock. 2

(10) Turn the machine on. Authorized workers should observe the equipment in operation to in-

sure repairs were done correctly.

2.9.3 Testing

The maintenance or electrical person may test the circuits by energizing the circuit for a short pe-

riod of time without voiding the lock out procedure provided. This may be done only when no other

work is being performed by any other person on the equipment being tested.

It is extremely important that all remote start switches be tagged with the “Do Not Operate” tag to

prevent inadvertent operation of the equipment during these periods.

2.9.4 Responsibilities

(1) It shall be the responsibility of the maintenance and electrical personnel to make sure this

procedure is adhered to.

(2) It shall be the responsibility of the maintenance and electrical personnel’s immediate super-

visor to instruct his personnel on this procedure.

(3) It shall be the responsibility of the Safety Officer with assistance from the Safety Committee,

Health Service Department, and the various managers and Vice-presidents to administer the

Lock Out / Tag Out Procedure.
