Energy Control Procedures Lockout/Tagout 29 CFR 1910. 147

Outline Ü Types and Magnitude of Energy Ü Recognition of Hazardous Energy Sources Ü The Nature of Lockout/Tagout Ü Methods of Energy Isolation Ü Verification of Isolation Ü Purpose of Energy Control Procedure

Types and Magnitudes Electrical- Volts Pneumatic- PSI Mechanical- (F= M x A) Hydraulic- PSI Chemical Thermal- Degree Gravitational (Potential / Kinetic F= M x A))

Further Recognition of Hazardous Energy Sources Ü Tensioned Objects, Elevated Objects. Potential Energy Ü Moving Objects- Kinetic Energy

The Nature of LOTO Ü When do we use LOTO? Servicing and Maintenance Normal Production Operations where: – Employees by-pass guard(s) – Employees place any part of their body in a hazardous area Exception: Minor tool changes- if repetitive, routine, and integral for production (alternative protection must be provided)

Lockout vs. Tagout Ü If capable of being locked out: Use Lockout Tags allowed, if they can be demonstrated to provide FULL EMPLOYEE PROTECTION

Full Employee Protection? Ü Tags attached at the same location as locks Ü Full compliance with all tagout provisions in 29 CFR 1910. 147 Tags are warning devices not physical restraints Tags are not removed, bypassed or ignored ( removed only be authorized employee) Tags must be securely attached Ü Additional means when necessary (i. e. removal of a valve handle)

LOTO Terminology Ü Affected employee Qualified Ü Authorized employee Ü Other Employee Ü Energy isolating device Ü Servicing and/or maintenance

Servicing and Maintenance Includes: Ü Setting up Ü Adjusting Ü Inspecting Ü Modifying Ü Constructing Ü Installing

Lockout/Tagout Requirements Ü Written program which includes specific written procedures Ü Training of employees (not just maintenance!) Ü Periodic review of procedures (employees)

Energy Control Procedure Ü Notification of employees Ü Preparation for shutdown Ü Machine or equipment isolation Ü Lockout/tagout device application Ü Release stored energy Ü Verification of isolation Ü Service Ü Release from lockout/tagout

Hazard Assessment Ü Assessment – (Service Maintenance Analysis Documentation) w Form review and completion

Exceptions for a written procedure: Ü For documentation exception you must meet all of the following: Machine has no potential for stored energy Machine has a single energy source Isolation of that source will completely de-energize Machine is isolated and locked out during maintenance

Documentation Exceptions (cont. ) A single lockout device will achieve locked-out condition Lockout device under exclusive control of employee Maintenance does not create hazard to others No previous accidents involving unexpected energization on this equipment

Lock/Tag Removal if Authorized Employee is not Available? Ü Verify that authorized employee is not at facility Ü Make reasonable efforts to inform him or her Ü Ensure that he/she knows of removal upon re-entering

Hardware must be: Ü Provided by the employer Ü Singularly Ü Only Ü Not identified devices used for control used for other purposes

Hardware must be (cont. ): Ü Durable – be able to withstand environment Ü Standardized – color, size, etc. Tags : print and format Ü Substantial – no accidental Tag attachment means: – – removal Withstand at least 50 pounds of force Not re-usable Self locking Attachable by hand

Hardware must be (cont. ): Ü Identifiable – Identify the employee who applied Legend -DO NOT OPERATE / DO NOT THROW SWITCH

Periodic Inspection Ü Performed at least annually Ü Lockout – include review with authorized employees Ü Tagout – include review with authorized and affected employees Ü Certification record kept: Identify machine or equipment Date of inspection Employees performing and included in inspection

Training and Re-training Ü Authorized employees Recognition of hazardous energy Type and magnitude of hazardous energy Methods of isolating energy How to verify isolation Ü Affected – Purpose and use of procedure Ü Other – Procedure and Prohibition from tampering Ü Tagout provisions

Re-Training is Required When: Ü Change in job assignment Ü Change in machine or process Ü Change in lockout/tagout procedure Ü Inadequacies revealed in periodic review

Other Requirements Ü Contractors? Communication – What procedures do they use? – Do they know what procedures you use? Ü Personnel or shift changes? Transfer lock procedure

Testing or Positioning Machines Ü Clear the machine of tools and materials Ü Remove employees from the area Ü Remove lockout/tagout devices Ü Energize and proceed with testing/positioning Ü De-energize and re-apply energy control measures

Group Lockout Ü Personal lock or tag (usually) Ü Lockbox or master tag system with principal authorized employee Ü Work permit system “Shall utilize a procedure which affords a level of protection equivalent to that provided by the implementation of a personal lockout or tagout device”
