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. Static electricity is generated by the abrasive flow through the blast hose. To minimize
the chance of static electric shock to operating personnel only use static dissipating blast
hose and install a grounding strap on the abrasive blaster.
Static electric shock hazard. To minimize the chance of static electric shock install a
grounding strap on the abrasive blaster and only use static dissipating blast hose.
6.1.2. 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.
6.1.3. 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.
6.1.4. Verify that all required personal protective equipment is available for each operator and
in good operating condition (safety glasses, safety shoes, ear plugs, gloves, airline filter,
respirator, & carbon monoxide monitor).
Critical: Adhere to all local, state, and federal
regulations including, but not limited to, OSHA (Occupational Health and Safety
Administration). Pay close attention to requirements regarding breathing air quality.
When an oil-lubricated air compressor is used, additional requirements for a high
temperature alarm and/or a carbon monoxide monitor become necessary. See Sections
3.9 and 3.10.
Failure to use personal protective equipment could result in serious injury or death.
6.1.5. Hose clamp the deadman (#12) to the blast hose assembly in a comfortable position
behind the nozzle holder (#25).
