Lockout/Tagout Affected Employees
Session Objectives • You will be able to: • Recognize hazardous energy sources • Carry out your responsibilities related to lockout/tagout • Understand the purpose and use of energy control devices and procedures
What You Need to Know • What hazardous energy is and how it is controlled • OSHA’s lockout/tagout regulations • Your responsibilities during and after lockout/tagout • Management’s responsibilities • Lockout/tagout devices and procedures
What Is Hazardous Energy? • Hazardous energy can be defined as: • Live or stored electricity; or • Machine or equipment parts that are still moving—or have the potential to move—after shut-off. • Hazardous energy is often invisible. In other words, it’s not immediately obvious that a hazard exists. That makes it especially hazardous.
What Is Hazardous Energy? (cont.) • Stored energy in equipment: • Heat • Gravity • Pneumatic, hydraulic, air and water pressure • Steam • Chemical
Hazardous Energy Injuries • Thousands of injuries every year • 80% of workers fail to turn off equipment • Causes: • Unexpected start-up • Release of stored energy • Failure to lock/tag out Image Credit: State of WA-WISHA Services
Controlling Hazardous Energy • Lockout: • Prevents machinery or equipment from being turned on (lockout device) • Prevents machinery or equipment parts from moving (lockout device) • Provides a warning (tagout device)
Lockout/Tagout Training • “Authorized employee” who services machinery • “Affected employee” who operates machinery. (If you do both then you must be trained as an authorized employee.) • “Other employee” who works near machinery
Your Responsibilities Related to Lockout/Tagout • Notify maintenance when equipment needs service or repair • Leave all lockout/tagout devices in place • Await instructions before using equipment • Verify equipment is safe to operate following lockout/tagout • Follow all safety rules while operating equipment
Management’s Responsibilities • Ensure de-energization of equipment • Ensure employee awareness • Provide appropriate levels of training • Review program effectiveness • Maintain and revise the lockout/tagout program • Administer appropriate discipline for violations
Energy Isolation Device • Isolate the equipment from the energy source • Isolation device • Circuit breaker • Pressure valve • Machine block
Lockout Device • Lock • Block • Chain • Multilock hasp • Wheel valve cover • Ball valve cover
Tagout Device • A tagout device is used when it is impossible to use a lockout device. Here are some things you should know about tag devices: • Warning device only • Readable • Attached securely • Resistant to degradation • Removed only by an authorized employee
Requirements for Lockout/Tagout Devices • Lockout/tagout devices must be: • Durable • Standardized • Substantial • Identifiable Image Credit: State of WA-WISHA Services
Typical Equipment Requiring Lockout/Tagout • Any machinery or equipment that contains or stores hazardous energy is subject to lockout/tagout. Examples include: • Presses • Power saws • Conveyors • Pumps • Production equipment • Trash compactors
When Lockout/Tagout Devices Must Be Used • Servicing or maintaining machinery or equipment • Hazardous energy exists • Unexpected start-up could occur • When in doubt, lock it out!
Actions That Trigger Lockout/Tagout • Any time an authorized employee could be injured by machinery or equipment during servicing or repair, it should be de-energized and locked out. • Examples include: • Removing or bypassing a safety device • Any part of the body is placed in harm’s way • Exposure to hazardous energy
Lockout/Tagout Exceptions • Work where the potential for hazardous energy does not exist • Activities performed during routine production processes • Work on cord-controlled devices • Hot tap operations where shutdown is not feasible Image Credit: State of WA-WISHA Services
Lockout/Tagout Procedure • Authorized employee will: • Notify affected employees • Shut down energized equipment • Isolate energy sources from equipment • Lock out or tag out the energy isolation device • Release stored energy • Test
Restart Procedure • Authorized employee will: • Clean up and inspect work area • Clear personnel from start-up area and notify affected employees of start-up • Remove lockout devices or tags and reenergize machinery or equipment • Restart equipment
Key Points to Remember • Hazardous energy is dangerous and deadly • Lockout/tagout is used whenever unexpected start-up or stored energy release could occur • Be sure to leave all lockout/tagout devices in place and wait for instructions before using equipment • Verify that equipment is safe to operate following lockout/tagout • Only Mangan trained employees are authorized to perform lockout/tagout. This training serves to train affected employees only. Notify Safety Admin for your training needs. safetytraining@manganinc.com
