Safety Training for Lockout - Tagoutin the Construction Industry
Disclaimer/Usage Notes • Photos shown in this presentation may depict situations that are not in compliance with applicable OSHA/MSHA/FHWA requirements. • It is not the intent of the content developers to provide compliance-based training in this presentation, the intent is more to address hazard awareness in the construction and mining industry, and to recognize the overlapping hazards present in many workplaces. • It should NOT be assumed that the suggestions, comments, or recommendations contained herein constitute a thorough review of the applicable standards, nor should discussion of “issues” or “concerns” be construed as a prioritization of hazards or possible controls. Where opinions (“best practices”) have been expressed, it is important to remember that safety issues in general and jobsites specifically will require a great deal of site- or hazard-specificity – a “one size fits all” approach is not recommended, nor will it likely be very effective.
Disclaimer/Usage Notes (continued) • No representation is made as to the thoroughness of the presentation, nor to the exact methods of remediation to be taken. It is understood that site conditions vary constantly, and that the developers of this content cannot be held responsible for safety problems they did not address or could not anticipate, nor those which have been discussed herein or during physical presentation. It is the responsibility of the employer, its subcontractors, and its employees to comply with all pertinent rules and regulations in the jurisdiction in which they work. • It is assumed that individuals using this presentation or content to augment their training programs will be “qualified” to do so, and that said presenters will be otherwise prepared to answer questions, solve problems, and discuss issues with their audiences. • Areas of particular concern (or especially suited to discussion) have additional information provided in the “notes” section of slides throughout the program…as a presenter, you should be prepared to discuss all of the potential issues/concerns, or problems inherent in those photos particularly.
Lockout - Tagout Control Of Hazardous Energy
You will learn… • Purpose of lockout-tagout • Requirements for LOTO • Types of hazardous energy • Procedures for LOTO
This happens often: Employee accidentally leaned on the start switch & turned on the machine himself...
Lockout • Prevents release of hazardous energy • Lock placed on appropriate energy isolating device that is in the off or closed position
Tagout • Identifies problem • Identifies lockout date • Identifies person • Used by itself only when cannot be locked out
Lockout/Tagout • Repaired • Serviced • Lubricated • Cleaned • Un-jammed • Adjusted • Maintained • Guard removed
Causes Of Injury • Failure to stop equipment • Failure to disconnect from power source • Failure to bleed energy • Accidental restarting of equipment • Failure to clear work areas before restarting
Types of Energy • Electrical • Mechanical • Chemical • Thermal • Hydraulic • Pneumatic
Mechanical Energy • Kinetic - machinery in motion • Gears • Belts • Potential - stored energy • Weights & springs • Pistons under pressure • Hydraulic controls
LOTO Procedure • Prepare for shutdown • Shutdown equipment • Isolate all energy sources • Place locks & tags • Release stored energy • Verify isolation
1. Prepare • Understand equipment hazards • Notify others of shutdown
2. Shutdown • Normal shutdown procedure • Turn all switches to OFF • Shut all control valves • Disable all sources of energy
3. Isolate Sources • Check all possible energy sources • Shut valves • Open breakers & disconnects
4. Place Locks • Valves • Breaker/electrical disconnects • Block or disconnect all lines
Plug Locks Ball Valve Gate Valve Hasp Electrical Hydraulic Pneumatic Lockout Devices
Use of Locks • Use only those issued to you • Never use another workers lock or tag • Tell supervisor if you need more LOTO equipment
5. Stored Energy • Block or release springs • Block elevated parts • Stop rotating flywheels • Relieve system pressure • Drain fluids • Vent gases
6. Verification • Prior to servicing or maintenance, authorized employee must verify that equipment is isolated by turning it on
Release From LOTO • Put all guards back • Remove tools • 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 lock and/or tag • A supervisor, after obtaining permission from the worker who placed the tag
Question • Equipment already has a lock and tag on it. Do I have to place my own locks & tags? YES. everyone working on equipment must place their own locks and tags
Contractors • All contractor employees must follow our LOTO procedures!
No Lockout • Performed or witnessed someone doing work without locking out • Disconnecting device is too far away or not convenient • Worker by themselves and felt no need to lockout • Not wanting to shut down equipment
LOTO Protects You • Use proper lockout - tagout procedures • Please be careful when working on equipment
Think First • Jaw crusher turned off… • No locks in sight… • Yellow hat is a man inside...
