Exception: Minor adjustments and servicing activities that take place during normal operations are not covered if they are repetitive, routine, and integral to the use of the equipment, provided that the work is performed using alternative measures that provide effective protection. A procedure written to isolate equipment that cannot be positively locked out. This procedure should afford the employee s a level of protection that is equivalent to that provided by a positive lockout device.
The potential energy in a device or mechanism, which, if released, would cause a motion or discharge. Examples include energy in a compressed spring, an elevated mass, the electrical charge stored in a capacitor, energy contained in compressed air, gas, steam, water, etc. To establish the accuracy of the lockout. Personal inspection and testing is acceptable verification also. A list identifying all energy sources including backup systems , devices, and their locations that must be locked out and tagged to prevent an inadvertent startup or release of energy.
A written procedure is not required if there is only one source of energy and the individuals are familiar with the necessary steps to de-energize the equipment or system. Assistant directors are responsible for the implementation of the LOTO policy in their departments and for the proper training of their employees.
Assistant directors also are responsible for enforcing any required disciplinary action. Shop managers are responsible for ensuring their employees are aware of the LOTO policy and that they follow all requirements. A qualified electrical person who will be primarily responsible for implementing LOTO procedures for the isolation of the 13kV distribution to a building or area of a building.
The system reliability technician is responsible for ensuring that equipment or systems specified in the written LOTO procedure are properly locked out and tested, provide confirmation of this to those individuals who will be working on such equipment or systems, and direct them to place their personal locks and tags at the appropriate locations.
All authorized employees are responsible for following the practices outlined in this program. The attached auditing checklist will be updated as required to ensure it remains current see Appendix B. Another person or group other than those using the energy control procedure being audited shall audit each unit at least once per year.
EHS is responsible for ensuring that all UM departments are audited at least annually. All contractors working on the UM campus will be given a copy of this policy by the Purchasing Department.

If you have not been on campus the last 3 days and will not be on campus the next 10 days, report your case and check exposure guidance here. Environmental Health and Safety. Lombard St.
Baltimore, MD Lockout Tagout Program. Authorized employee: A person who locks and tags or implements a LOTO procedure on equipment or systems to perform servicing or maintenance on such equipment. Blank: To physically block the flow of gas, liquid, etc. Supervisory locks will be used to lockout equipment for an extended period of time. The supervisor will retain all supervisory locks and keys. Only the employee who applies a safety lock may remove it. If the employee is not available to remove a lock, specific procedures in Section The authorized employee will notify affected employees that equipment is to be locked out.
The equipment under repair is to be locked and tagged by ALL workers performing service on the equipment. The lock may be removed ONLY by the authorized employee who placed it on the equipment, except in special circumstances as described in this chapter. Energy must be isolated so that it is not possible to inadvertently re-energize the equipment. Before work is started, all pneumatic, hydraulic, or other fluid lines in the machine must be checked for stored energy.
All pressure must be vented or safely isolated from the area where work is to be done. Contents of line accumulators or tanks must be drained as necessary. Valves must be locked in either the open or closed position as the situation requires preventing a buildup of pressure. Any mechanisms under spring tension or compression must be blocked, clamped, or chained in position if the stored energy cannot be safely released.
Any suspended mechanisms or parts which might drop or cycle through a lower position must be moved to a safe position, or if necessary blocked, clamped or chained in place.
All moving parts must be at rest and the start button must be activated to assure that the machine is in a zero mechanical state before starting work. Operating controls must be returned to the OFF position after the isolation of the equipment is verified. Equipment with power panels at public locations must be locked out or positively disabled at two separate locations.
Plug-in cord equipment operated by a single electrical source will be unplugged and a TAGOUT sign attached to the plug, unless the plug is under the exclusive control of the employee or constant sight of the employee. If another authorized employee will be continuing the repair, then the status of the repair must be forwarded to that employee.
All guards must be installed. All exposed electrical wiring must be covered. Using Drones to Improve Workplace Safety As drones become more accessible, companies are exploring how to best use its capabilities.

Contents Show Content. Training - Employees must be given training about the program. This should include how to use and remove energy control devices. Evaluation - The facility is required to perform an annual evaluation of the lockout tagout program to ensure it is effective.
During this evaluation the facility must identify any changes to machines that would require an update to the program.
This evaluation should also look at whether employees are properly following the program. If they are not, additional training or enforcement may be necessary. Electricity - This is the most common source of energy. It typically comes from a main electrical cable that goes into a machine. Other sources of traditional electricity could be a gas or diesel generator or battery backup systems.
Hydraulic Pressure - Hydraulic pressure is commonly used in presses, lifts, and other similar machines. If there is hydraulic pressure in a line, it should be discharged prior to work beginning. Hydraulic Accumulation - Hydraulic accumulation is a similar type of energy, but is found in a pump rather than in the lines. Disconnecting a hydraulic pump and making sure any stored energy is discharged is essential. Pneumatic Energy - Using compressed air is common in certain types of machinery.
Compressed air can be stored in lines, pipes, tanks, or other locations. Identify any potential areas where compressed air could be present and ensure the program accounts for it. Gas - Gas is a common source of energy. While not commonly used in modern machinery that requires a lockout tagout program, it does need to be considered.
Steam - Steam is still a very effective source of energy and is used in a variety of industries. Identifying steam energy sources in a machine is critical for the success of any lockout tagout system. Thermal - Thermal energy comes from heat. Most machines create heat, and even if it is not intended to activate a machine, this should be considered. Looking at all the possibilities is essential for an effective program.
Gravity - When power is removed from a system, it is often going to be more susceptible to gravitational energy. As electrical brakes release, this energy can make machines move, which is why it is so critical that it is a part of a lockout tagout program. Kinetic - Tension from springs or other sources needs to be accounted for to keep the maintenance teams safe. Preparing for Shutdown - Machine operators should prepare the machine for proper shutdown.
Many machines have shutdown sequences that need to be followed to ensure all the energy is dissipated. Actual Shutdown - Complete the actual shutdown of the machine. Disconnecting Power - Disconnect a machine from its main power source and all other energy sources. Locking Out the Power - Apply a lockout or tagout device to the energy sources of the machine. Secure Machine - Take steps to release any stored energy or residual energy, and then secure any parts that need to be secured.
Verification - Take whatever steps are necessary to verify that the machine has been completely de-energized.
