Hazardous Energy Control Program

Procedures

1. Application of Lockout Control

Each department chair/director/manager shall be responsible for developing written lockout procedures for the machines and equipment under their control or ownership, which require such procedures. The written procedure shall meet all of the requirements of MIOSHA Part 85 c(4)(ii).

Cord and plug connected electrical equipment, for which exposure to the hazards of unexpected energization or startup to the equipment is controlled by the unplugging of the equipment from the energy source, is exempt from the written procedure requirement provided that the unplugged cord is under the exclusive control (the plug must be within sight or three feet of the employee at all times during the work) of the employee(s) conducting the service or maintenance activities. A written procedure is also not required when a piece of equipment has only a single source of energy which can be readily identified and isolated provided that: when locked out with a single locking device, the equipment will be completely de-energized and deactivated, the lockout device is in the exclusive control of the authorized employee performing the work, the work does not create a hazard for other employees, and MTU has had no accidents involving unexpected energization or activation of the equipment.

1. Preparation for Shutdown - Personal safety locks and keys will be kept by each individual operator, mechanic, electrician. Supervisors will also have their own locks and keys. Authorized employees shall review the written lockout procedure to have complete understanding of the type(s) and magnitude of the energy, the hazards of the energy to be controlled, and the methods or means to control the energy.
   
   
2. Notification of Employees - Affected employees shall be notified by the authorized employees that the machine or equipment is going to be locked out.
   
   
3. Machine or Equipment Shutdown - The machine or equipment shall be turned off or shut down using the energy control procedures established for the machine or equipment.
   
   
4. Machine or Equipment Isolation - All energy isolating controls that are needed to control the energy of the machine or equipment shall be physically located and operated in such a manner as to isolate the machine or equipment from the energy sources (e.g., steam, pneumatic, hydraulic). A Zero Energy State must be proven. If the valves do not permit the use of a standard lockout, another method such as wire cable and lock can be used. When gravity is a source of hazardous energy the affected component must be physically blocked to isolate the hazard.
   
   
5. Lockout Device Application - The multiple lock adapter and lock shall be affixed in such a manner as to hold the energy isolation devices in a safe or off position.
   
   
6. Notification of Affected Personnel - Affected employees shall be notified by the authorized employees that the machine or equipment is locked out. In addition to verbal notification, a sign indicating a power lockout condition will be placed near the machine/equipment controls.
   
   
7. Verification of Isolation - Prior to starting work on a machine or equipment that has been locked out, each authorized employee involved shall verify that the isolation and de-energization of the machine or equipment have been accomplished by testing the effectiveness of the lockout by attempting to cycle the machine or start the equipment at the motor control center panel or start/stop switch.
   
   Each authorized employee will notify other authorized and affected personnel in the area that they are going to attempt to cycle the machine or equipment prior to doing so and shall ensure that personnel are free and clear of the machine or equipment prior to operating the controls.
   
   If the controls activate the machine or equipment or cause any machine or equipment movement, each authorized employee will begin again at step A, Preparation for Shutdown.
   
   If there is the possibility of re-accumulation of stored energy to a hazardous level, verification or isolation shall be continued until the servicing or maintenance is completed, or until the possibility of re-accumulation no longer exists. Stored or potential energy will be relieved, restrained, or otherwise made safe.
    
8. Begin Work Activity - Work activity will begin once each authorized employee involved has verified that the current control of hazardous energy sources has been effective.
