Administrative Policy Statement

The Lockout Safety Program—Requirements for the Control of Hazardous Energy

(Approved by the Executive Director of Health Sciences Administration by authority of Executive Order No. 1 and the Executive Vice President by authority of Executive Order No. 5)

1.  Policy

Special measures are required to isolate all equipment from any potentially hazardous energy in order to protect the safety of staff, faculty, students, and visitors when, during the servicing or maintenance of equipment, the unexpected start-up, energization, or release of stored energy could cause injury.

2.  Definition of Hazardous Energy

Hazardous energy may be any energy that could cause harm to a worker such as:

  • Electrical

  • Mechanical/stored (such as pneumatic, hydraulic, springs, parts moved by gravity, spinning flywheels, pressurized systems, etc.)

  • Radiation

  • High intensity electromagnetic fields

  • Chemical

3.  Procedures

All equipment must be locked out during servicing or whenever inadvertent operation or release of hazardous energy could cause injury.

Each department that performs equipment service operations must develop procedures for locking out equipment, consistent with the standardized procedures provided by the Environmental Health and Safety Department.

4.  Training

All employees who service or maintain equipment must be trained in the lockout or tagout procedure, and in recognizing safety locks and tags.

5.  Contractor Compliance Requirement

Public works and service contractors who work on University equipment for which this procedure applies, must have a formal lockout program consistent with the University's Lockout Safety Program. Contractors must submit copies of their written lockout programs and lists of their trained employees for review by the hiring University department and the Environmental Health and Safety Department before starting any work.

Any equipment lockout procedure necessary to the work of a contract must be coordinated with the appropriate University unit(s)—for example, the Physical Plant Department. An exchange of information between the outside employer and the on-site employer should be listed as an agenda item for the preconstruction meeting (in accordance with WISHA Regional Directive 91-9A, pg. 14).

After work commences, the hiring University department shall be responsible for monitoring contractor compliance with this requirement.

6.  Equipment Purchases

Equipment purchased by University departments or as part of vendor-supplied systems must accept energy isolating controls and personal protection locks.

7.  Additional Information
