scope:

PURPOSE. This instruction establishes a program consisting of energy control procedures, employee training and periodic inspections. The program is to ensure machines, equipment, and systems are isolated from the energy source, placed in a zero energy state, and rendered inoperative by the placement of lockout and tagout devices before any employee performs any servicing or maintenance work where the unexpected energization, start-up, or the release of stored energy could occur and cause injury.

APPLICABILITY. The requirements in this instruction are applicable to all Marshall Space Flight Center (MSFC) organizations including on-site and off-site contractors that are performing servicing and maintenance activities at MSFC. This instruction establishes the minimum requirements for the control of such hazardous energy at MSFC.

There shall be no exceptions to the safe practices required by the energy control (lockout/tagout) requirements in this instruction for work performed on MSFC machines, equipment, and systems.
