2 IntroductionMost accidents are caused by the uncontrolled release of hazardous energy. Many of these accidents can be prevented by proper lock-out/tag-out procedures.OSHA’s standard is designed to prevent needless deaths and serious injury to workers by controlling hazardous energy.
3 Training OverviewThis training is intended to provide a general overview of Lock-out/Tag- out Systems used in today’s workplace.This awareness information will not provide specific direction in using lock-out/tag-out in confined space rescue operations.
4 Course Objectives Define what is lock-out/tag-out Determine when lock-out/tag-out should be usedDefine energy as it applies to this areaApply lock-out/tag-out guidelinesDescribe procedures for removing lock-out/tag-out
5 Lock-OutA disconnect switch, circuit breaker, valve or other energy isolating mechanism is put in a safe or “off” position.A device is often placed over the energy isolating mechanism to hold it in a safe position.A lock is attached so the equipment cannot be energized.
6 Tag-OutIn a tag-out, the energy isolating device is placed in a safe position and a written warning is attached to it. All lock-out/tag- out materials are supplied by the employer.
7 WhenLock-out/tag-out is necessary whenever you are performing service or maintenance around any machine where you can be injured.When placing any portion of your body in a position that may be caught in moving machineryAny work in or near electrically charged machinery.
8 Mechanism of Injury Unexpected start-up of the equipment Release of stored energy
9 What is Energy?Energy can be defined in many areas. For the purposes of these guidelines, energy is defined as the following:Energy is the movement or the possibility of movementWhenever the power switch is “on” or “off”, energy as some sort is always present in any powered equipmentEnergy can come from the force caused by the motion of an object, or potential energy, or force stored in an object that is not moving.
10 applying lock-out/tag-out guidelines Preparation for Shut Down Before you turn off any equipment, in order to lock or tag it out, you must know:The type and amount of energy that powers itThe hazard of that energyHow the energy can be controlled
11 applying lock-out/tag-out guidelines Preparation for Shut Down Shut the system down by using its operating controls.Follow the proper procedure which is right for that equipment.Assistance from employees knowledgeable with the equipment
12 Equipment Isolation Equipment Isolation Operate all energy isolating devices so the equipment is isolated from its energy sourceBe sure to isolate all energy sources, secondary power supply, as well as the main oneNever pull an electrical switch while it is under loadNever remove a fuse instead of disconnectingEquipment IsolationverificationMake sure all danger areas are cleared of personnelVerify that the main disconnect switch or breaker can’t be moved to “on” positionPress all start buttons and other controls on the equipmentShut off all machine controls when testing is finished
13 Application of Lock-Out/Tag-Out Isolating devices are to be locked, tagged or bothUse only standardized devices supplied by your employerIf tags are used instead of locks, attach them at the same point as a lock or as close as possibleIf no tags available, post a firefighter at the energy source
14 Control Stored EnergyTo guard against stored energy residual; do any of the following.Inspect the systemRelieve trapped pressureRelease tension on springsBlock or brace parts that may fallGravityBleed the lines and leave vent port openProcess piping systems and close valves
15 Removing Lock-Out/Tag-Out Contact Incident CommandRemove only the tags you put in placeMake sure equipment is safe to operateRemove all tools from work areaSafeguard all employeesConduct a head count to assure everyone is clear of the equipment and make notification that lock-out/tag-out is being removedFollow a check list if there are required steps to re-energize the system
16 FactoidsAccording to OSHA, how many workplace deaths are attributed to improper use of lock-out/tag-out annually?According to OSHA, 2% of workplace deaths could be avoided by proper implementation of lock-out/tag-out procedures.What are the four major types of energy sources which require lock-out/tag-out?ElectricalMechanicalHydraulicChemical
17 They must be reviewed annually in the workplace. FactoidsWhat is the last step of the lock-out/tag-out procedure?Verify the isolation of energy and assure stored energy has been released.How often should lock-out/tag-out procedures be inspected?They must be reviewed annually in the workplace.
