The requirements of this RAC do not apply to:

• Activities in machinery, equipment and installations where safeguards ensure effective protection of workers from exposure to hazardous energies created by an unexpected energy release and workers do not expose any part of the body to the danger zones associated with the operation of machinery, equipment or installations.
• Equipment which can be de-energized by unplugging from an electrical outlet, when the person doing service or maintenance has exclusive control of the plug (working alone) and the electricity is the only energy source present.

NOTE: Activities associated with the lifting of load by equipment owned, leased or rented by Vale, including service provider lifting equipment that are part of a contract scope with Vale, from the following types of lifting equipment: cranes, overhead cranes, monorail lifting systems, lifting booms, mobile cranes, hoist and any other lifting equipment or lifting system11.
