CITY OF LAKEVILLE By: Duane Zaun ayor TTEST: Char Friedges, City erk • • CITY OF LAKEVILLE LOCKOUT/TAGOUT ~ PROCEDURE • • PURPOSE Lockoutltagout procedures are precautions designed to make sure that machines do not cause accidental injury to people. This procedure establishes the minimum requirements for the lockout of energy isolating devices whenever maintenance or servicing is done on machines or equipment . It will be used to ensure that the machine or equipment is stopped, isolated from all potentially hazardous energy sources and locked out before employees perform any servicing or maintenance where the unexpected energization or start-up of the machine or equipment or release of stored energy could cause injury. COMPLIANCE WITH THIS PROGRAM All employees are required to comply with the restrictions and limitations imposed upon them during the use of lockout. The authorized employees are required to perform the. lockout in accordance with this procedure. Employees must never attempt to start, energize, or use a machine or equipment that is locked out. • DEFINITIONS The following are definitions of words and phrases used in this procedure: Affected employee - An employee whose job requires him or her to operate or use a machine or equipment on which servicing or maintenance is being performed under lockout or tagout; or whose job requires him or her to work in an area where such servicing or maintenance is being performed. Authorized employee - A person who locks or implements a lockout system procedure on machine or equipment to perform the service or maintenance on that machine or equipment. An authorized employee and an affected employee may be the same person when the affected employee's duties also include performing maintenance or service on a machine or equipment which must be locked or tagged out. Capable of Being Locked Out - An energy isolating device is considered capable of being locked if it is designed with a hasp or other attachment which a lock can be fastened on or through, or if the device has a locking mechanism built into it. Other energy isolating devices are considered capable of being locked out if lockout can be achieved without the need to dismantle, rebuild, or replace the energy isolating device or permanently alter its energy control capability. • Energized -Connected to an energy source or containing residual or stored energy. 1 • t • Energy Isolating Device - A mechanical device that physically prevents the transmission or release of energy. Examples include; but are not limited to a manually operated electrical circuit breaker; a disconnect switch; a manually operated switch by which the conductors of a circuit can be disconnected from all undergounded supply connectors and no pole can be operated independently; a slide gate; a slip blind; a line valve; a block; and any similar device used to block or isolate energy. The term does not include push button, selector switch, and other control circuit type devices. Energy Source -Any source of electrical, mechanical, hydraulic, pneumatic, chemical, thermal, or other energy. Hot tap - A procedure used in maintenance and service activities which involves welding on a piece of equipment under pressure in order to install connections or appurtenances. It is commonly used to replace or add sections of pipeline without the .interruption of service for air, gas, water, steam, and petrochemical distribution systems. Lockout -The placement of a lockout device on an energy .isolating device, in accordance with an established procedure, ensuring that the energy isolating device and. the equipment being controlled cannot be operated until the lockout device is removed. • Lockout Device - A device which utilizes a positive means, such as a lock ke or ~ Y combination type), to hold an energy isolating device in the safe position and prevent the energizing of a machine or equipment. Normal Production Operations -The utilization of a machine or equipment #o perform its intended production function. Service and/or Maintenance -Workplace activities such as construction, installing, setting up, adjusting, inspecting, modifying, and maintaining or servicing machines or equipment. These activities include lubrication, cleaning, unjamming of machines or equipment, and making adjustments where the employee may be exposed to the unexpected energization or start-up of the equipment or release of hazardous energy. Setting up -Any work performed to prepare a machine or equipment to perform its normal production operation. Tagout -The placement of a tagout device on an energy isolating device, in accordance with an established procedure, to indicate that the energy isolating device and the equipment being. controlled may not be operated until the tagout device is removed. 2 • r . SEQUENCE OF LOCKOUT 1. Before shutdown -All affected employees will be notified that. servicing or maintenance is required on a machine or equipment and that the machine or equipment must be shut down and locked out to perform the servicing or maintenance. 2. Before shutdown -The authorized employee must know the type and magnitude of the energy that the machine or equipment utilizes, shall understand the hazards of the energy to be controlled, and .shall know the methods or means to control the energy. 3. During shutdown -The authorized employee will shut down the machine or .equipment by the normal stopping procedure (depress stop button, open switch, close valve, etc.) 4. Isolation -The main power switches, circuits, or other sources of energy will be moved to the "off' position, etc. The energy isolating device(s) will be deactivated so that the machine or equipment is isolated from the energy source(s). 5. Lockout -Locks will be placed on switches or other energy sources in the "safe" or "off' position. Warning tags will be placed with each lock. All lockout and tagout • devices must indicate the identity of the employee applying the device. All tagout devices must warn against hazardous conditions if the machine or equipment is energized. All lockout and tagout devices must contain the following warning, "DO NOT START, DO NOT OPEN, DO NOT CLOSE, DO NOT ENERGIZE, DO NOT OPERATE". 6. Energy Release -.All potentially hazardous stored or residual energy (such as that in springs, elevated parts, rotating flywheels, hydraulic systems, electrical systems, and air, gas, stream or water pressure, etc.) is relieved, disconnected, or otherwise made safe by repositioning, blocking, bleeding down, etc. (If there is a possibility of reaccumulation of stored energy to a hazardous level, verification of isolations will be continued until the servicing or maintenance is completed, or until the possibility of such accumulation no longer exists.) Stored or residual energy (such as that in capacitors, springs, elevated machine members, rotating flywheels, hydraulic systems, and air, gas, steam, or water pressure, etc.) must be dissipated or restrained by methods such as grounding, repositioning, blocking, bleeding down, etc. 7. Testing - After ensuring that no personnel are exposed, and as a check on having disconnected the energy sources, the authorized employee will operate the push button or other normal operating controls to make certain the equipment will not' operate. CAUTION: Return operating control(s) to neutral or "off' position after • verifying the isolation of the equipment. 3 r , The machine or equipment is now locked out. RESTORING EQUIPMENT TO SERVICE When the servicing or maintenance is completed and the machine or equipment is ready to return to normal operating condition, the following steps will be taken. 1. Check the machine or equipment and the immediate area around the machine or equipment to ensure that nonessential items have been removed and that the machine or equipment components are operationally intact. 2. Check the work area to ensure that all employees have been safely positioned or removed from the area. 3. Verify that the controls are in neutral. 4. Remove the lockout device and reenergize the machine or equipment. 5. Notify affected employees that the servicing or maintenance is completed and the machine or equipment is ready to use. TRAINING Training must be provided to ensure that the lockout/tagout procedures are understood by employees. The training must include the following: - Recognition of applicable hazardous energy sources, the type and magnitude of energy sources in the workplace, and the methods and means necessary for energy isolation and control - The purpose and use of energy control procedures. - The lockout/tagout procedures and the prohibition of restarting or reenergizing machines which are locked out or tagged out. When tagout systems are used, employees must be made aware of the following: - Tags are warning devices fastened to energy isolating devices, and do not provide the physical restraint that is provided by a lock. 4 - ? . - When a tag is attached, it is not to be removed, bypassed, or ignored, except. by authorized employees, - Tags must be legible and understandable by all effected employees. - Tags and their means of attachment must be made of material that will withstand environmental conditions encountered in the workplace. - Tags may evoke a false sense of security, so their meaning as it applies to the overall energy control program must be understood by all employees. - Tags must be securely attached to energy isolating devices, so they cannot be inadvertently or accidentally detached. 5
