and check that the helmet fits firmly on
the head. Tighten the chin strap if
necessary.
7. Press the button and insert the lung
demand valve in the connector.

lung demand valve has snapped into place.
9. Seal the tailpiece with your thumb and inhale until a negative

11. Check the exhalation valve: Seal the tailpiece and exhale

12. Connect the overpressure self-contained breathing apparatus or
overpressure airline equipment.
13. Check the proper fit by turning and pulling the lung demand valve
vigorously.
Have a second person check the tightness and correct connection.
