As the lower spindle rotates it moves down the square drive of the spindle and towards the outlet
sealing rim in the valve body.
14.31
When the sealing face of the lower spindle contacts the sealing rim this closes the valve
preventing high pressure air discharging from the cylinder.
14.32
When closing the valve use finger and thumb pressure only. Do not use excessive force.
14.33
From the closed to the fully open position, the valve requires
more
than two full revolutions of
the hand wheel.

Safety precautions
14.36
BA set maintenance is to be carried out in the RPE maintenance room.
14.37
At operational incidents/training venues the BA set should be taken to the designated RPE
maintenance area.
14.38
SDBA cylinders must have a cylinder cover fitted when connected to a BA set.
14.39
Cylinders are only to be transported in purpose built boxes/racks and fitted with red protective
plastic blank cap.
14.40
Personnel must only carry one cylinder at a time. They should be carried vertically ensuring that a
firm grip is taken around the cylinder neck (see image 1136782 below).
14.41
The cylinder valve opening must always be directed away from yourself and other personnel.
14.42
When removing a cylinder from a horizontal rack, slide it gently forward and support the
underside with the free hand until the weight can be transferred fully to the carrying hand and a
secure grip confirmed.
14.43
Never fully empty a cylinder
, as this will allow contaminants and or moisture to enter the
cylinder.
