Failure to follow the procedures below could result in serious injury or death. In addition to these
procedures completely read and understand all sections of this Operation and Maintenance Manual.
The AirPrep System is a pressurized vessel. Propelled objects will cause serious injury or death.
Depressurize vessel before performing any maintenance. See Section 6.2.
This section contains part identification numbers (#) within the text that are found on the Figure 6.1. Refer
to these drawings as needed while reading this manual.
6.1 AirPrep System Setup Procedure (see Figure 6.1)
6.1.1 Confirm that the AirPrep System has been properly maintained and inspected as detailed in
Section 8.0.
6.1.2. Verify that all required personal protective equipment is available for each operator and in
good operating condition (safety glasses, safety shoes, ear plugs, and gloves). Critical:
Adhere to all local, state, and federal regulations including, but not limited to, OSHA
(Occupational Safety and Health Administration).
Failure to use personal protective equipment could result in serious injury or death.
6.1.3. Make certain that the AirPrep System is not pressurized. Follow the depressurizing
procedure given in Section 6.2.
Airborne particles and loud noise hazards from 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.
6.1.4. Do Not operate this equipment without a pressure relief device in place. The ASME Code
requires that all vessels be provided with pressure relief devices. See Section 3.11.
Rupture Hazard. Operating the pressure vessel above the maximum allowable working
pressure can result in rupturing the pressure vessel. Install an air pressure relief valve to
protect against over pressurization of the blast vessel. See Section 3.11.
6.1.5. To minimize chance of static electrical shock to operating personnel only use anti-static
hoses and properly install an earth ground to the AirPrep System. See Section 5.12.
Static electric shock hazard. To minimize chance of static electrical shock to operating
personnel only use anti-static blast hose, properly electrically bond the blast nozzle, blast
hose couplings, and the equipment, and properly install an earth ground to the abrasive
blaster. See Section 5.12.
