We had a leak at work the other day 1/4 npt test port let go at 3500lbs lost 600 gallons of hydro oil in a couple mins. The whole place looked like the fog rolled in .it all atomized and the operator still didnt wanna shut the pumps off . We had to run in the room and shut them down manually, got soaked and my partner was throwing up .People forget when atomized you have an explosion hazard as well.
