1 Environmental Health and Safety
Lock Out Tag Out (LOTO) BGSU Environmental Health and Safety July 2006

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

3 Why is LOTO important? The Lock Out/Tag Out procedure prevents the unexpected start up or release of stored energy that could cause injury to employees by placing a lock and/or warning tag on an energy isolation device.

4 LOTO Program Enforcement
A violation of a University 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.

5 Regulatory Agencies Federal: Occupational Safety and Health Administration (OSHA) State: Public Employment Risk Reduction Program (PERRP)

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

7 OSHA’s LOTO Standard 29 CFR 1910.147
Requires a written energy control program that includes defined energy control procedures Requires documented employee training Requires periodic inspections at least annually Requires certain equipment specifics Defined energy control procedures such as: Equipment specific procedures, group LOTO, shift changes, trouble shooting procedures, etc.

8 BGSU’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 BGSU’s LOTO Program Office of Design & Construction Responsibilities
Notify contractors to bring their LOTO program to preconstruction meeting; and Include LOTO as an agenda item & allow contractors & EHS dept. to discuss

10 BGSU’s LOTO Program Supervisor’s Responsibilities
Complete equipment specific LOTO procedures; Conduct annual & periodic inspections; Keep a list of authorized employees; Issue LOTO devices to employees; Ensure all affected employees are properly trained on LOTO procedures; Enforce compliance with BGSU’s LOTO program; and Provide employees with copies of the LOTO Program upon request.

11 BGSU’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. Authorized employee: An employee who performs servicing or maintenance on machines and/or equipment. Affected employee: An employee who performs the duties of his/her job in an area in which the LOTO procedure is implemented & servicing or maintenance activities are performed.

12 BGSU’s LOTO Program Contractors
Contractor & on-site employer 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. The person responsible for bringing in the contractor will be responsible for providing a copy of BGSU’s LOTO program and resolving any conflicts between the two written procedures.

13 BGSU’s LOTO Program Equipment
Must be singularly identified; Must be the ONLY devices for controlling energy; and Must NOT be used for any other purposes.

14 BGSU’s LOTO Program Equipment
LO devices must be durable & withstand the environment to which they are exposed. TO devices must be constructed & printed so they do not deteriorate or become illegible; LO/TO devices must be standardized by color, shape or size; LO/TO devices must be substantial enough to prevent early or accidental removal and removal without excessive force.

15 BGSU’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 BGSU’s LOTO Program Equipment
One key will be issued to the authorized employee applying the lock. Additional keys will only be used to remove locks in the event the abandoned lock procedure must be implemented. The Bowling Green campus will retain an additional key in the lock shop. Firelands College will retain an additional key under the supervision of the Building Maintenance Superintendent.

17 BGSU’s LOTO Program Equipment
TO devices must include a legend such as: DO NOT START, DO NOT OPEN, DO NOT CLOSE, DO NOT ENERGIZE, DO NOT OPERATE, etc. TO devices must have standardized print and format.

18 BGSU’s LOTO Program Required TO Device Information
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.

19 BGSU’s LOTO Program Equipment
An approved warning tag will accompany all lockouts. The warning tag will be attached directly to the lockout device by a nylon tie.

20 BGSU’s LOTO Program Equipment
If equipment must be locked out for an extended period, extended locks will be issued. Extended locks will be distinguished as such, including a separate tag.

21 BGSU’s LOTO Program Procedures
Preparation for shutdown Shutting down the equipment Equipment isolation Application of LOTO devices Release of stored energy Verifying equipment isolation

22 BGSU’s LOTO Program Prep For Shutdown
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

23 BGSU’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.

24 BGSU’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).

25 BGSU’s LOTO Program Application of Devices
Use valve covers, plug locks, etc. if the lock can’t be placed directly on the energy control. When LO is used, every employee in the work crew must attach their personal lock.

26 BGSU’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.

27 BGSU’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.

28 BGSU’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.

29 BGSU’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.

30 BGSU’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.

31 BGSU’s LOTO Program Shift Changes
If servicing lasts more than one shift, LOTO protection CANNOT be interrupted. The original authorized employee will remove their lock & the incoming employee will place theirs on the isolating device. If the first employee leaves prior to the replacement’s arrival, a supervisor may place their lock on to ensure safety. The incoming authorized employee MUST VERIFY that ALL energy sources are locked out prior to beginning work.

32 BGSU’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 in the Lock Shop. Extra keys are controlled by the Lock Shop at Main Campus and by the Building Maintenance Superintendent at Firelands. If the supervisor can’t be reached, contact the Director of Maintenance & Trades or the Mechanical Trades Coordinator at Main Campus. Abandoned Lock Procedure Form filed in the Lock Shop at Main Campus and by the Building Maintenance Superintendent at Firelands.

33 BGSU’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.

34 BGSU’s LOTO Program Equipment Specific LOTO
Equipment Specific LOTO forms 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.

35 BGSU’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.

36 BGSU’s LOTO Program Equipment Specific Exceptions

37 BGSU’s LOTO Program Training
Supervisors Authorized Employees All Affected BGSU Employees BGSU employees: why lockout tagout systems are used; how to recognize lockout tagout devices; the importance of not disturbing lockout tagout devices and; who to call for information on lockout tagout.

38 BGSU’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.

39 BGSU’s LOTO Program Periodic Inspections
An inspection 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. The supervisor must certify that the inspections have been performed.

40 BGSU’s LOTO Program Periodic Inspections
Where LO is used, the inspector must review each authorized employee's responsibilities under the procedure with that employee (group meetings are acceptable). Where TO is used, the inspector must review BOTH the authorized and affected employee's responsibilities with those employees for the energy control procedure being inspected.

41 BGSU’s LOTO Program EH&S Assistance
