LOCKOUT/TAGOUT

Subpart J General Environmental Controls 1910.147 The control of hazardous energy Lockout/Tagout

Outline Scope, Application, Purpose Definitions Energy Control Program Energy Control Procedure Material and Hardware Periodic Inspection Training and Communication

Could Cause Injury To Employees Scope Scope Servicing and maintenance of machines and equipment where . . . Unexpected energization or Start up or Release of stored energy Could Cause Injury To Employees

Scope Exceptions: Construction, agriculture, maritime Electric utilities Electric utilization installations (Subpart S) Oil & gas well drilling & servicing

Must Provide Alternative Protection Application Control of Energy Normal production operations not covered unless . . . Remove or bypass a guard or safety device Part of body is in point of operation Must Provide Alternative Protection

Application Exceptions: Cord & plug connected electric equipment Only energy source Person performing work – exclusive control Hot tap operations – transmission & distribution systems for: Gas, steam , water or petroleum Pressurized pipelines where continuity of service is essential Alternative protection is still essential

Purpose Requires Employers To: Establish a program Utilize procedures

Definitions Employees Affected Other Authorized Person who uses lockout/tagout Affected Person who operates or uses machine where lockout/tagout is being performed or Works in area Other All “other” employees

Definitions Energized Energy Source Connected to energy source Contains residual or stored energy Energy Source Electrical, mechanical, hydraulic, pneumatic, chemical, thermal, or other energy

Energy Control Program Energy Control Procedures Periodic Inspections Employee Training

Lockout or Tagout? If energy isolating device cannot be locked out: If energy isolating device can be locked out: Lockout or Attach at same location as lockout Provide equivalent level of safety as lockout

Energy Isolating devices shall be designed to accept a lockout device! After January 2, 1990 . . . Whenever a replacement or major repair, renovation or modification or new machines or equipment are installed: Energy Isolating devices shall be designed to accept a lockout device!

Energy Control Procedure Develop, document and utilize Exceptions to documentation (all must exist): No potential for stored or residual energy after shut down Single energy source – readily identified & isolated Locking out will completely deenergize equipment Equipment isolated from energy source during work Single lockout device is needed Lockout device under exclusive control of worker Work does not create hazard for other employees Employer – no accidents utilizing this exception

Energy Control Procedures Purpose of procedure Procedural steps for shutting down, isolating, blocking an securing Procedural steps for placement, removal and transfer of lockout/tagout devices Who’s responsible? Requirements for verification

Materials and Hardware Provided by Employer Locks, tags, chains, wedges, key blocks, adapter pins, self-locking fasteners etc. Not used for any other purpose Durable Standardized Color shape or size Substantial Identifiable Employee Tagout – warning such as Do Not Start

Periodic Inspection At least annually Ensures procedure and requirements of standard are being met Conducted by authorized employee Not the one utilizing energy control procedures Correct deviations or inadequacies Include interview with authorized and affected

Periodic Inspection Certification Identify machine or equipment utilizing lockout/tagout Date of inspection Employees included in inspection Person performing inspection

Training Must ensure purpose and function of program are understood by employee Must ensure the knowledge and skills required for safe application, usage, and removal of energy controls are acquired by employee

Training Authorized Recognition of hazardous energy sources Type and magnitude of energy available Methods and means for energy isolation & control Limitations of tags Affected Purpose & use of energy control procedure Limitations of tags Other Knowledge of procedure Prohibited to restart or reenergize

Retrain Employee Retraining Change in job assignment Change in machines, equipment Change in processes present a new hazard Change in energy control procedures Whenever periodic inspection shows deviations or inadequacies Must reestablish employee proficiency Certify Retrain

Application of Energy Control Preparation for shutdown Machine or equipment shutdown Machine or equipment isolation Apply lockout/tagout devices Stored energy Verification

Release from Lockout/Tagout Check machine Notify employees (check area for employees) Removed by person who applied device Removal by person other than one who applied device

Outside Contractors Inform each other of respective lockout/tagout procedures On-site employer ensure employees understand and comply with restrictions and prohibitions of outside employer’s energy control program

Group Lockout/Tagout Every authorized employee working on equipment One person – one lock Each person remove only his/her lock when done working Responsibility given to one authorized employee to coordinate

Shift Changes Specific procedures must be utilized Ensure continuity of lockout/tagout Provisions for orderly transfer of lockout/tagout devices

Enforcement of Procedures Important!!!
