In a lockout, an energy isolating device is locked in a safe or off position.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
In a lockout, an energy isolating device is locked in a safe or off position. This means that when a lockout is implemented, the energy isolating device is physically locked in a position that prevents the release or transmission of energy. This ensures the safety of workers who are performing maintenance or repairs on machinery or equipment, as it prevents unexpected startup or release of energy that could cause harm or accidents.
