Control, or lockout, of energy sources prevents the unexpected energization, start-up, or release of stored energy that could cause injury during maintenance, repair, or servicing of machines, equipment, and electrical circuits.Responsibility
University managers, supervisors and lead workers are to comply with and enforce all provisions of this policy and the unit's written lockout program.
Unit supervisors are responsible for:
- Developing and implementing a written lockout program.
- Ensuring that affected personnel receive lockout procedure training. See below.
- Documenting lockout procedure training for each employee.
Employees are to comply with all provisions of this policy and the unit's written lockout program.Assistance
Direct questions relating to this policy and the development and implementation of a lockout program to EH&S; telephone 335-3041.REQUIREMENTS
Administrative units develop and implement written lockout programs if employees perform one or more of the following:
- Maintain machines, equipment, or electrical circuits,
- Repair machines, equipment, or electrical circuits, and/or
- Service machines, equipment, or electrical circuits.
An administrative unit maintains the written lockout program as part of the unit's overall accident prevention program.Hazardous Energy Sources
Include the following information in the written lockout program:
Describe the machines, equipment, and service and maintenance activities which include hazardous energy sources. See definition of hazardous energy sources below.Employee Locks
Direct each employee to apply and remove their own energy-controlling device (i.e., lock) when performing service and maintenance requiring the control of hazardous energy.Lockout Procedures
Describe a general lockout procedure for machines and equipment which contain a single energy source that can be isolated and locked-out with a single lock.
Describe specific lockout procedures for each machine and piece of equipment having multiple lockout points, multiple energy sources, and/or stored energy.Templates
Environmental Health and Safety (EH&S) designs lockout program and procedure templates to simplify the development and implementation of lockout programs. Contact EH&S for templates; telephone 335-3041.Control of Hazards Hazardous Energy Sources
Hazardous energy sources include, but are not limited to:
Service and Maintenance Activities
An administrative unit must control hazardous energy sources if an employee performs service or maintenance activities during which the employee:
Service and maintenance activities include:
- Removes or bypasses guards or other safety devices; or
- Places any body part into an area on a machine or piece of equipment where work is actually performed, i.e., the point of operation.
Cord and Plug Powered Devices
- Unjamming, and
During maintenance and service activities, disconnect any machine or piece of equipment powered by a cord and plug inserted into an electrical outlet receptacle.Moving Parts
The person performing the maintenance or service is responsible for control of the plug.
Administrative units do not have to include maintenance and service activities performed on cord and plug powered machines or equipment in the written lockout program.
Departments must use machine safeguards on all machines and equipment which expose employees to moving parts during operation. See 3.62 .Lockout Devices
An administrative unit assigns personal locks to each employee required to routinely lockout machinery or equipment.Lock Requirements
Persons required to lockout machines and equipment on a nonroutine basis can checkout locks and tags from the unit.
Each lock must be:
- Operated by a single key,
- Equipped with a label or tag identifying the person applying the lock,
- Used only for locking out during maintenance and service activities, and
- Standardized within a unit (locks can be standardized by color, size or shape).
Supervisors are responsible for ensuring that affected individuals receive training about the unit lockout program and procedures. Employees whose work operations include areas where hazardous energy sources may be present must receive this training.Documentation
Contact EH&S for training materials; telephone 335-3041.
Supervisors must document the training by recording the following information:
Submit a copy of the training documentation to Human Resource Services.
- Training subject,
- Employee name, and
- Date(s) of training.
