LOTO on the Auraria campus

1. Lock Out Tag Out (LOTO) AHEC Environmental Health and Safety Department Last Revised: May 2023

2. Outline Importance of Lock Out/Tag Out (LOTO) OSHA’s Control of Hazardous Energy standard AHEC's LOTO Program EH&S Assistance

3. 3 What is Lockout/Tagout? Control of hazardous energy - including electrical, mechanical, hydraulic, pneumatic, chemical, thermal, or other sources Procedures to prevent accidental startup of equipment that’s being serviced or repaired and to ensure stored energy cannot be released Lockout – putting a lock on circuits that power equipment Tagout – warns employees you’re working on equipment and to not touch the lock

4. Hazardous Energy Sources Electrical Mechanical (i.e. motors, drive belts) Chemical (i.e. natural gas, propane) Thermal Pneumatic Hydraulic

5. 5 LOTO Takes out the Guesswork Many injuries happen when co-workers turn on equipment that’s being worked on Or stored energy is released LOTO prevents accidents

6. 6 Leading Causes of LOTO Injuries No. 1: Failure to shut off equipment No. 2: Failure to disconnect equipment from power source No. 3: Unexpected startup No. 4: Failure to remove tools and debris that can become flying projectiles, before restarting equipment

7. OSHA’s LOTO Standard 29 CFR 1910.147 Requires a written energy control program that includes defined energy control procedures Trouble shooting procedures Shift changes Requires documented employee training Requires periodic inspections at least annually Requires certain equipment specifics

8. AHEC's LOTO Program Environmental Health & Safety Responsibilities Coordinate the LOTO program; Training & assistance with annual inspections; Maintain copies of equipment specific lock out procedures, annual inspections & training records; and Update & evaluate the LOTO program annually.

9. AHEC's LOTO Program Project Management Responsibilities Notify contractors to bring their LOTO program to preconstruction meeting; and Include LOTO as an agenda item & allow contractors & AHEC trades or EHS. to discuss, as needed Ensure an appropriate MOP is created and reviewed by affected trades during project work.

10. AHEC's LOTO Program Supervisor’s Responsibilities Complete equipment specific LOTO procedures; Create MOP for multi-trade support (i.e. electrical oversight) for all operational work Ensure inspection of equipment specific LOTO procedures are completed at least annually; Maintain LOTO devices and supplies for employees; Ensure all affected employees are properly trained on LOTO procedures; Enforce compliance with AHEC's LOTO program; and Provide employees with copies of the LOTO Program upon request.

11. AHEC's LOTO Program Authorized Employee Responsibilities Attend EH & S’s required training; Follow all LOTO procedures; Assist supervisor’s in completing equipment specific LOTO procedures; Consult supervisors when questions or concerns arise; and Notify all affected employees of LOTO activities.

12. AHEC's LOTO Program Contractors Contractor & AHEC must exchange LOTO info On-site employees must understand & comply with the contractor’s rules. Employees must be alert & aware of any new types of LOTO devices.

13. LOTO Program Enforcement A violation of AHEC’s employee's responsibility must be reported to the employee's immediate supervisor for appropriate action. A violation of a contractor’s responsibility must be reported to the project manager (or the person who hired the contractor) for appropriate action.

14. AHEC's LOTO Program LOTO Equipment Must be the ONLY devices for controlling energy and singularly identified as such Must NOT be used for any other purpose Must be durable & withstand the environment to which they are exposed. Must be standardized by color, shape or size; TO devices must be constructed & printed so they do not deteriorate or become illegible; LO devices must be substantial enough to prevent early or accidental removal and removal without excessive force.

15. AHEC's LOTO Program Equipment Lock out will be accomplished using a lock and key. Chains, or other hardware, may be used in conjunction with the lock to isolate the energy source.

16. AHEC's LOTO Program Equipment Each shop will have a specific color lock. Each lock will be keyed separately. Master keys will only be used to remove locks in the event the abandoned lock procedure must be implemented.

17. AHEC's LOTO Program Required TO Device Information An approved warning tag will accompany all lockouts. The warning tag will be attached directly to the lockout device by a nylon tie. Name of authorized employee who locked out equipment; Authorized employee’s radio or phone number, including contractors; Date and time of lockout; and Brief description of work being performed .

18. AHEC's LOTO Program Procedures Preparation for shutdown Shutting down the equipment Equipment isolation Application of LOTO devices Release of stored energy Verifying equipment isolation

19. AHEC's LOTO Program Prep For Shutdown Create a MOP to coordinate with other shops and/or contractors and schedule electrical support. Know the types and amounts of energy that power specific equipment Know the hazards of that energy Know how the energy can be controlled – review equipment specific procedures if necessary Direct any questions to immediate supervisor

20. AHEC's LOTO Program Shutting Down Equipment Notify ALL affected employees that a LOTO procedure is being used and why. Shut the equipment down using operating controls. Follow proper procedure for the equipment to avoid endangering anyone during the shutdown.

21. AHEC's LOTO Program Energy Isolation LO & TO energy isolating sources with assigned locks and tags. Usually requires locking out electrical disconnect. Be sure to isolate ALL energy sources (secondary as well as primary).

22. AHEC's LOTO Program Application of Devices Use valve covers, plug locks, etc. if the lock can’t be placed directly on the energy control. Every employee in the work crew must attach their personal lock and tag.

23. AHEC's LOTO Program Application of Devices A TO system alone is not acceptable at any time unless the equipment is not capable of being locked out. The tag must be placed at the same location that the lockout device would have been attached, and additional measures must be taken to ensure the level of safety is equivalent to that obtained by using a lock. This includes: blocking of a controlling switch, removal of an isolating circuit element, opening of an extra disconnect device, or removal of a valve handle ONLY .

24. AHEC's LOTO Program Release of Stored Energy Inspect the system to make sure all parts have stopped moving. Disperse stored energy (springs, hydraulic systems, air, gas, water pressure, or steam). If stored energy can build up again, monitor it to make certain it stays below hazardous levels.

25. AHEC's LOTO Program Verifying Equipment Isolation Make certain all dangerous areas are clear of personnel. Verify that the equipment cannot be turned to the “on” position. Press all “start” buttons and activating controls on the equipment. Return all controls to the “off” position after certain that LO is effective.

26. AHEC's LOTO Program Removing LOTO Devices/Restoring Equipment Safeguard all employees by making certain everyone is clear of the equipment. Also notify affected employees of impending re-energization. Verify that all tools have been removed and all guards reinstalled. Remove LOTO devices. Each device must be removed by the person who put it on. Energize equipment.

27. AHEC's LOTO Program Troubleshooting Remove all tools & personnel from the area. Notify affected employees of impending re-energization. Authorized employees remove the LO device but MUST leave tag in place. Energize equipment. When finished, de-energize & reapply LO device.

28. AHEC's LOTO Program Shift Changes If servicing lasts more than one shift, LOTO protection CANNOT be interrupted. The incoming authorized employee MUST VERIFY that ALL energy sources are locked out and ADD their personal lock prior to beginning work.

29. AHEC's LOTO Program Abandoned Lock Procedure Verify authorized employee has left the worksite & notify them that their lock is being removed. LOTO devices may ONLY be removed if supervisor is present & authorizes removal. After all communication attempts are complete & the equipment has been inspected, energy can be restored. An abandoned lock procedure form must be filled out & filed with EH&S.

30. AHEC's LOTO Program Exceptions Work on cord & plug equipment IF it is unplugged, the plug remains within arms reach during servicing and authorized employee has exclusive control of the plug. If guards aren’t removed or bypassed & are effective in preventing worker exposure to hazards created by the unexpected energization or start up of machines or equipment, or the release of energy.

31. AHEC's LOTO Program Equipment Specific LOTO Equipment Specific LOTO procedures must be completed by the supervisor and/or the authorized employee. All equipment specific procedures must be easily accessible or posted directly on the equipment. An inspection/review will be conducted at least annually by an authorized employee not involved in the procedure being inspected. The inspection will identify any deficiencies in or deviations from the program.

32. AHEC's LOTO Program Periodic Inspections For LOTO procedures on specific equipment: the inspector must review each authorized employee's responsibilities under the procedure with that employee (group meetings are acceptable). Where TO only is used, the inspector must review BOTH the authorized and affected employee's responsibilities with those employees for the energy control procedure being inspected.

33. AHEC's LOTO Program Equipment Specific Procedures Procedures must be updated when: New equipment is installed; or New energy sources are added to a facility or individual equipment; or Magnitude of an energy source changes; or Designated isolation points change. Deficiencies are noted during periodic inspection

34. AHEC's LOTO Program Training Supervisors Authorized Employees All Affected AHEC Employees

35. AHEC's LOTO Program Re-Training Change in authorized employee’s job assignments or job area that contains sources of hazardous energy; Change in machines, equipment or process that presents a new hazard; Change in energy control procedures; Need for refresher training found during periodic inspections; and/or Employer believes there are deviations from, or inadequacies in, the employee’s knowledge or use of LOTO procedures.
