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 Abrasive Blaster Operation and
Maintenance Manual.
The Abrasive Blaster is a pressurized vessel. Propelled objects will cause serious injury or death.
Depressurize vessel before performing any maintenance. See Section 6.2.
6.1 Abrasive Blaster Setup Procedure (see Figure 6.2)
6.1.1. Confirm that the abrasive blaster is properly maintained and inspected as detailed in
Section 8.0.
6.1.2. Static electricity is generated by the abrasive flow through the blast hose. 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 5.10.
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 5.10.
6.1.3. 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.
6.1.4. Make certain that the abrasive blaster 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.
6.1.5. Properly install the handway cover (#22) and gasket (#34). See Section 6.3.
