Lockout tagout steps
When you think you need to perform a Lockout Tagout, follow these six steps, which apply to all machines or equipment, so every worker should be familiar with them.
All persons who are expected to be affected by the Lockout Tagout shall be notified by their supervisor or authorized person prior to commencing any work. Based on the complexity or nature of the machine or device, scope of work expected duration of work, associated process, type, number and location of energy isolators, start-up regulations, etc., a preparatory work plan shall be developed to ensure appropriate Lockout tagout.
Use the appropriate machine shutdown steps to stop operational control or return it to neutral mode.
3. The isolation
All relevant energy isolators shall be operated/placed in such a way as to isolate the machine from energy.
Locks and hangings shall be applied to each energy isolator by an authorized person, and lock machine fixtures shall keep the energy isolator in a "safe" position. The personnel tag shall be attached to the energy isolator.
The machine should be tested for residual energy. If detected, measures should be taken to release or limit the stored energy.
After completing the Lockout tagout, and before starting work, the following steps should also be taken: Operate the machine controllers (buttons, switches, etc.) to verify that the energy isolation has been completed. Upon completion of verification, deactivate the controller or return it to neutral mode. Inspect the machine by test instrument and visual inspection to verify that the machine has completed the energy isolation.
For example, maintenance of machinery and equipment:
1. Identify the dangerous energy of the equipment requiring Lockout tagout and notify all personnel affected by the Lockout tagout
2. Shut down the machine to ensure that all moving parts have stopped
3. Locate the dangerous energy isolation device and turn the switch to the "off" position
4. Safe energy locking using a personal Lockout Tagout device
5. Test whether there is stored potential energy or kinetic energy in the machine
6. Verify that the machine is in the safe "zero" energy state, and then start to test the machine's non-reactive action
