Lost of consciousness and danger of suffocation by inhaling higher concentrations!

Avoid R744 emission and uncontrolled deflating, particularly in closed rooms!

If uncontrolled emission of R744 occurs, take the following measures:

  1. Leave the room immediately, warn people, ensure sufficient ventilation.
  2. Only enter the area with self-contained breathing apparatus if the atmosphere has not been proven to be non-hazardousness.
  3. Stay outdoors on the side facing the wind. Close off the area.
  4. Replace the pressure relief valves of the compressors after venting, as the opening pressure may be reduced/decreased after this kind of event.
  5. Check the system's pressure relief valves for tightness after venting and replace if necessary.
