7.3 Ending the Blast Operation (See Figure 7.3)
Do not leave the abrasive blaster pressurized during long periods of no usage. Undetected air
leaks can cause costly wear damage to the pressure vessel (i.e. at abrasive inlet and handways).
7.3.1. Close the air inlet ball valve (#3). The ball valve is closed when the handle is fully
turned to the position shown in Figure 7.3 (handle perpendicular to body). The handle
tab will bottom against the ball valve body in the closed position.
Do not turn off the air compressor and allow the abrasive blaster air pressure to back
flow through the air supply system. Back flow will carry abrasive into the moisture trap
(#7) and contaminate the controls.
7.3.2. Completely depressurize the abrasive blast vessel (#1) by slowly opening the blowdown
ball valve (#4). See Section 6.2 for blowdown procedure.
Airborne particles and loud noise hazard from the blowdown exhaust air can cause
serious injury and loss of hearing. Wear approved eye and ear protection. Stay clear of
blowdown air path. DO NOT place hands or other body parts in the blowdown air path.
Make sure no personnel are in the blowdown air path.
7.3.3. For long periods of non-usage remove remaining blast abrasive from blast vessel to
minimize moisture contamination. Replace lid (#29) to prevent debris from entering
blast vessel (#1).
Removal of abrasive is more critical when using steel abrasive since moisture can cause
it to solidify in the pressure vessel.
