1 CONTROL OF HAZARDOUS ENERGY “LOCKOUT/TAGOUT” (LOTO)
2 LOCKOUT/TAGOUTThe OSHA Standard for the Control of Hazardous Energy (Lockout/Tagout) 29 CFR covers the servicing and maintenance of machines and equipment in which the unexpected start-up or the release of stored energy could cause injury to employees.
3 WHAT IS LOCKOUT/TAGOUT? “LOTO” is a technique used to prevent energy from being released during the servicing of equipment. This is accomplished by placing locks on energy isolation devices prior to starting work.
4 TYPES OF ENERGY CHEMICAL ELECTRICAL HYDRAULIC MECHANICAL THERMAL PNEUMATIC Some energy sources can be turned on/off. Others can only be dissipated or controlled.
5 CHEMICALHAS ENERGY THAT CAN START FIRES, CAUSE SKIN BURNS, GENERATE HARMFUL GASES OR FUMESBEFORE WORKING-RELEASE, DRAIN OR VENT CHEMICALS SAFELY
6 Electrical AS LOW AS 30 VOLTS CAN CARRY ENOUGH CURRENT TO KILL USE NON-CONDUCTING TOOLSDISCHARGE ALL CAPACITORS AFETR LOCKOUTENSURE ALL CONTROL POWER IS DE-ENERGIZEDLOCK & TAG SOURCE BREAKERS NOT SWITCHESSTORED POTENTIAL ENERGY CAN BE RELEASED DURING WORK CAUSING INJURY OR DEATHCHECK CIRCUTS DEAD BEFORE WORKING
7 HYDRAULIC ENERGY OF LIQUIDS UNDER PRESSURE RELIEVE PRESSURE SLOWLY INTO A PROPER CONTAINERRAPID RELEASE CAN CAUSE INJURYPRESSURE CAN CAUSE EQUIPMENT TO MOVE
8 MECHANICAL KINETIC-IN MOTION ENERGY OF MOVING MACHINERY CAN CAUSE, AMPUTATIONS, LACERATIONS, FRACTURES & LOSS OF LIFEPOTENTIAL-STORED ENERGY
9 THERMAL ENERGY OF HEAT (& COLD) HOT EQUIPMENT & FLUIDSD WILL BURN YOU COLD FLUIDS CAN CAUSE INJURY ALSOQUICK RELEASE OF COMPRESSED GASES CAN FREEZE YOUR SKINALLOW EQUIPMENT TO REACH A SAFE TEMPERATURE BEFORE STARTING WORK
10 PNEUMATIC ENERGY OF COMPRESSED GASES - UNCONTROLLED RELEASE CAN CAUSE INJURY-RAPID DE-PRESSURIZATION CREATES EXTREME LOW TEMPERATUREPROPERLY VENT ALL SYSTEMS BEFORE STARTING WORK
11 Working on unfamiliar machinery is a hazard FIRST STEPS IN LOTOKNOW YOUR EQUIPMENT& SYSTEMS:hazardsisolation pointsproceduresWorking on unfamiliar machinery is a hazard
12 WHAT YOU NEED FOR LOTO WRITTEN LOTO SCHEDULE LOCKS & TAGS-IDENTIFIED FOR THE WORKERHASPS-FOR PLACING LOCKS & TAGSBREAKER CLIPS-FOR ELECTRICAL LOTOBLANK FLANGES-FOR FLUID LINESVALVE COVERS-FOR LOTO OF VALVESPLUG BUCKETS-FOR ELECTRICAL PLUGS
13 WHO CAN REMOVE LOCKS & TAGS??? ONLY THE EMPLOYEE WHO PLACED THE TAG “OR” A SUPERVISOR, AFTER OBTAINING PERMISSION FROM THE WORKER WHO PLACED THE TAGEACH PERSON WORKING ON THE EQUIPMENT MUST PLACE THEIR OWN LOCKS & TAGS TO ENSURE THEIR SAFETY, EVEN IF THE EQUIPMENT ALREADY HAS A LOCK & TAG ON IT.
14 LOCKOUT/TAGOUT: SHIFT CHANGES If servicing lasts more than one shift, lockout/tagout protection must not be interrupted.When the employee who applied device is not there to remove it, it can be removed only in an emergency and only under the direction of the supervisor.
15 LOTO PROTECTS YOU!!! USE PROPER PROCEDURES…. PLEASE BE CAREFUL WHEN WORKING ON EQUIPMENT
16 How Injuries Occur During the Servicing of Equipment? 80% failed to turn off equipment10% equipment activated by someone else5% failed to control potential energyMost of remaining 5% disconnected power but failed to verify effectiveness
17 WHEN IS LOTO APPLIED? Tool changes Adjusting Inspecting Modifying Replacing partsClearing jamsLubricatingCleaningTool changesThere are some situations where LOTO is not required…
18 EXCEPTIONS TO LOTO Normal production operations Routine, repetitive, & integral to productionGuards/safety devices not bypassedBody part not placed in the point of operation or other dangerous area during machine cycleNeed to use alternative measures for protectionCord & plug connected equipmentPlug is only source of energyPlug is under continuous control of one person
21 LOCKOUT/TAGOUT DEVICES Durable – Lockout and tagout devices must withstand the environment to which they are exposed for the maximum duration of the expected exposure. Tagout devices must be constructed and printed so that they do not deteriorate or become illegible, especially when used in corrosive or wet environments.
22 DEFINITIONS:Energy Isolating Device - A mechanical device that physically prevents the transmission or release of energy.Energy Control Procedure - Safety program adopted by the employer that includes energy control procedures plus provisions for inspecting the procedures and training employees for lockout/tagout.Authorized Employee - one who locks out machines or equipment in order to perform the servicing or maintenance on that machine or equipment.Affected Employee - one whose job requires him/her to operate or use a machine or equipment on which servicing or maintenance is being performed under lockout, or whose job requires him/her to work in an area in which such servicing or maintenance is being performed.
23 TIDBITS OF INFORMATION: Never attempt lockout/tagout procedures unless you have been trained and certified by your employer under an approved Energy Control Program.Never loan or share your lock, combination, or key with anybody else.Always be sure all lockout/tagout devices are compatible with the environment in which they will be used i.e. corrosive, humid, etc.
24 SUMMARYAll hazardous energy sources must be controlled (kinetic & potential).Control via energy isolation device (do not rely on control circuit).Only use designated lock for LOTO.Tags must accompany all locks.Nine-step general procedure – remember to verify isolation.Protection must be ensured during special situations.OSHA STANDARD…
