1、Lockout-Tagout,Control of Hazardous EnergyOSHA Standard 1910.147,You will learn,Purpose of Lockout-TagoutRequirements for LOTO Types of Hazardous Energy Procedures for LOTO,Types of Energy,Electrical Mechanical Chemical Thermal Hydraulic Pneumatic,Electric shock can kill,as low as 30 volts can carry
2、 enough current to kill,Use Safe Electrical Practices,Use non-conducting tools Check circuits dead before working Lock&Tag source breakers not switches Ensure all control power is de-energized Discharge all capacitors after Lockout,Mechanical Energy Hazards,2 Types Kinetic in motionPotential-stored,
3、Kinetic Energy Hazards,Energy of moving machinery can cause Amputations Lacerations Fractures Loss of life,Potential Energy Hazards,Energy stored in machinery Weights&Springs Pistons under pressure Hydraulic controls Stored potential energy can be released during work causing injury or death,Chemica
4、l Energy Hazards,Chemicals have energy that can start fires cause skin burns generate harmful gases or fumes Before working release,drain or vent chemicals safely,Thermal Energy Hazards,Energy of Heat(and cold)Hot equipment&fluids will burn you Cold fluids can cause injury also Quick release of comp
5、resses gases can freeze your skin Allow equipment to reach a safe temperature before starting work.,Hydraulic Energy,Energy of Liquids Under Pressure pressure can cause equipment to move rapid release can cause injury or ejection of system parts Relieve pressure slowly into a proper container,Pneuma
6、tic Energy Hazards,Energy of Compressed Gases uncontrolled release can cause injury rapid de-pressurization creates extreme low temperature Properly vent all systems before starting work,First Step In LOTO,Know your equipment&systems hazards isolation points procedure for Lockout Working on unfamili
7、ar machinery is a hazard,Who Can Lockout Equipment?,Only Employees who have been trained and authorized by management,Items needed for LOTO,Written LOTO schedule Locks&Tags-identified to the worker Hasps-for placing locks&tags Breaker Clips-for electrical LOTO Blank Flanges(pancakes)-for fluid lines
8、 Valve Covers-for LOTO of Valves Plug Buckets-for electrical plugs,Use of Locks&Tags,Use only those issued to you Never use another workers lock or tag Ask your supervisor if you need more LOTO equipment,6 Step LOTO Procedure,Prepare for Shutdown Shutdown Equipment Isolate all energy sources Place L
9、ocks&Tags Release Stored Energy Verify Equipment Isolation,1.Prepare for Shutdown,Understand equipment hazards Notify other workers of shutdown,2.Shutdown Equipment,Use normal shutdown procedure Turn all switches to OFFShut all control valvesDisable all sources of energy,3.Isolate All Energy Sources
10、,Shut valves Open breakers&disconnects,4.Place Locks&Tags on,ValvesBreakers/electrical disconnectsBlock or disconnect all linesLock and tag blank flanges,5.Release or Block allStored Energy,Discharge capacitors Block or release springs Block elevated parts Stop rotating flywheels Relieve system pres
11、sure Drain fluids Vent gases Allow system to cool,6.Verify Equipment Isolation,Check all other workers are clear Check locking devices securely placed Check isolation Attempt normal startup Return Controls to OFF/Neutral,Release from LOTO,Inspect Area and Equipment Ensure all Machine Guards in place
12、 Move tools away from equipment Inform others of startup Restore system connections Remove Locks&Tags Restore equipment to normal Conduct normal startup,Who can remove Locks&Tags?,Only the employee who placed the tagora supervisor,after obtaining permission from the worker who placed the tag,A piece of equipment already has a lock and tag.Do I have to place my own locks&tags?,YES.Each person working on the equipment must place their own locks and tags to ensure their safety.,Lockout-Tagout Protects YOU!,USE Proper Lockout-Tagout ProceduresPlease be careful when working on equipment,
