Hazardous Energy Control Program

Application 

6. When Lockout Methods Are Not Required

• Minor tool changes (for example, changing a drill bit) are not covered when a stop button is used to control unexpected motion during the tool change or minor adjustment and when the start button is both visible and under the employee's immediate control.
  
  
• Other minor servicing activities that take place during normal production operations are not covered by this standard if they are routine, repetitive, and integral to the use of equipment for production and if work is performed using alternative protective measures that provide effective employee protection.
  
  
• Cord and plug connected equipment must be unplugged and under the exclusive control of the employee performing the service or maintenance work. The plug must physically be in the possession of the employee, or in arm's reach and in the line of sight of the employee. Lockout devices are available to lock out the plug when disconnected if these conditions can not be met.
  
  
• Repair, trouble-shooting and set-up adjustments must be performed on energized equipment only when it is absolutely necessary to leave the machine energized. For the purpose of this procedure, the trouble-shooting process will end and a lockout will be required whenever:

• Power is shut off.
  
  
• A particular problem has been located and repairs start.
  
  
• Circuit changes are being made.
