  3. Jockey pump control valves that are sealed or locked in the open position.
  4. Control valves to commercial kitchen hoods, paint spray booths or dip tanks that are sealed or locked in the open position.
  5. Valves controlling the fuel supply to fire pump engines that are sealed or locked in the open position.
