CFR 1910.133.
1.6. PROTECT YOUR LUNGS.
Do Not operate this equipment without wearing OSHA approved respiratory protection.
Abrasive blasting produces dust contaminated with toxic substances from the abrasive used, the
coating being removed, and the object being blasted. This dust may contain silica which can
cause severe and permanent lung damage, cancer, and other serious diseases. Do Not breathe
the dust. Do Not rely on your sight or smell to determine if dust is in the air. Silica and other
toxic substances may be in the air without a visible dust cloud. If air-monitoring equipment for
silica is not provided at the worksite, then all personnel MUST wear appropriate respiratory
protection when using or servicing this equipment. Breathing air supplied to respirators must be
of acceptable quality. Consult your employer and OSHA regarding the appropriate respiratory
protection and breathing air quality. See Sections 3.9, 3.10, and OSHA 29 CFR 1910.134.
Abrasive blasting produces dust which may contain silica and other toxic substances that can
cause severe and permanent lung damage, cancer, and other serious diseases if inhaled. Wear
OSHA approved respiratory protection. See Sections 3.9, 3.10, and OSHA 29 CFR 1910.134.
1.7. BREATHING AIR QUALITY.
Do Not use breathing air that does not meet OSHA Class D standards. Extreme caution must be
taken when selecting a source of breathing air. Breathing air provided by an oil-lubricated air
compressor can contain carbon monoxide; therefore, use of a carbon monoxide detector is
required (See Section 3.10). Carbon monoxide can be in the compressed air produced by an oil-
lubricated air compressor when it is operated at extremely high temperature; therefore a high
temperature alarm is required to alert the operators when this condition exists. See Section 3.9
and reference OSHA 29 CFR 1910.134(i).
Extreme caution must be taken when connecting to factory air sources. Factories can have
sources of compressed gases such as nitrogen which is fatal if used as a breathing air source.
Verify that the air source is breathable air.
Breathing air must meet OSHA Class D standards. Use of breathing air sources that do not meet
Class D standards can cause asphyxiation and result in death. Verify that all air sources are
breathable quality and use a high-temperature alarm and a carbon monoxide monitor when
required. See Sections 3.9, 3.10 and OSHA 29 CFR 1910.134(i).
Enclosed blast areas must be ventilated to reduce airborne dust to an acceptable level as
required by OSHA 29 CFR 1910.1000.

1.34. DEPRESSURIZE VESSEL BEFORE PERFORMING MAINTENANCE.
Do Not remove, repair, or replace any item on this equipment while it is pressurized. Do Not
attempt to perform maintenance or load abrasive while this equipment is pressurized or is even
capable of being pressurized. This means the inlet ball valve should be closed and the air supply
should be shut off or disconnected. Anytime the manual blowdown valve is closed it should be
assumed that the abrasive blast vessel is pressurized.
An abrasive blaster is a Pressurized Vessel. The compressed air inside a pressurized vessel
contains a dangerously high level of energy which can propel objects and cause serious injury
or death. Depressurize vessel before performing any maintenance. See Section 6.2.
1.35. ALWAYS USE REMOTE CONTROLS.
Do Not sell, rent, or operate abrasive blasters without remote controls. OSHA regulations
require remote controls on all abrasive blasters. All abrasive blasters must be equipped with
automatic (deadman) type remote controls (either pneumatic or electric). Failure to use remote
controls can cause serious injury or death to the operator(s) or other personnel in the blasting
area. Reference OSHA 29 CFR 1910.244(b).
1.36. NEVER USE BLEEDER TYPE DEADMAN VALVES.
Do Not use bleeder type deadman valves on any Schmidt® abrasive blaster. The use of A-BEC,
Clemco, or a similar bleeder type deadman valve can, without warning, cause unintentional
start-up which can result in serious personal injury. A particle of dirt from the air hose can plug
the bleed hole in the deadman valve and cause the blast outlet to turn on.
1.37. CHECK FOR DAMAGED PARTS.
Do Not use this equipment with damaged components. Damaged components can fail during
operation and result in serious injury or death to operating personnel. Periodically check all
valves, hoses, and fittings to see that they are in good condition. Repair any component that
shows any sign of wear or leakage. See Section 8.0.
1.38. ALWAYS USE SAFETY PINS ON HOSE COUPLING CONNECTIONS.
Do Not use this equipment without hose coupling safety pins in place and hose whip checks
installed on all air and blast hoses. All blast hose couplings and air hose couplings have pin
holes that must be safety pinned to prevent accidental disconnections. Accidental hose
disconnection can cause serious injury or death. See Section 5.14 and 8.7.
1.39. ALWAYS USE CORRECT REPLACEMENT PARTS AND ACCESSORIES.
Do Not use replacement parts or accessories that are not rated for pressures equal to or higher
than the abrasive blaster’s operating pressure. Improper hoses and/or fittings used on, or
connected to the abrasive blaster can rupture and cause serious injury or death.
Do Not use replacement parts that are not Schmidt original factory replacement parts. Non-
original parts may not fit properly and can cause equipment damage and/or failure which can
result in serious injury to operating personnel. Consult Axxiom Manufacturing, Inc.
Use of replacement components that are not Schmidt original factory replacement parts may

2.4 Vessel Information
2.4.1. All pressure vessels used in Bulk Abrasive Blasters are manufactured in strict
accordance with the provisions of the ASME Code Section VIII, Div. 1 and are
registered with the National Board of Boiler & Pressure Vessel Inspectors, 1055
Crupper Avenue, Columbus, Ohio 43229. Should Manufacturer’s Data Reports be
required they may be obtained from the National Board for a small fee.
2.4.2. In order to maintain the high level of quality and quality control used in the manufacture
of this vessel, it is required that any and all welded repairs to this vessel be performed
by a reputable shop holding a National Board “R” Stamp and/or an ASME “U” stamp,
depending on state or city law. Welding on the vessel performed by welders not
properly qualified per the ASME Code voids the ASME/NB integrity of that particular
vessel.

2.6 Bulk Abrasive Blaster Lifting Diagrams
An abrasive blaster is a Pressurized Vessel. The compressed air inside a pressurized vessel
contains a dangerously high level of energy which can propel objects and cause serious injury
or death. Depressurize vessel before lifting, moving, or transporting.

Carefully read and follow all the recommendations regarding the abrasive blast system installation
requirements. Improper installation can result in equipment malfunction and significant lost time
expenses. Consult an authorized Schmidt® distributor or Axxiom Manufacturing, Inc.
3.1 Abrasive Blast System Installation Location
i. Portable units: Units equipped with trailers are portable and can be rolled to locations
where blast jobs are performed. Locate the unit to allow accessibility to the manway and for
ease of abrasive filling. Pay close attention to objects that may be in the path of the pressure
vessel exhaust air (depressurization).
ii. Stationary units: Units that will be installed in permanent locations require careful
consideration. Stationary units can be installed below an abrasive hopper with a support
structure that can limit access to the abrasive blast system. Install stationary blast systems in
a position that will allow access to the manway and the blaster piping. These areas must be
accessible to perform required maintenance. Pay close attention to objects that may be in the
path of the pressure vessel exhaust air (depressurization). See Section 6.2. The bulk abrasive
blaster manual blowdown valve typically does not have an exhaust hose however; one can
be installed to direct the exhaust air flow into a blast room. NOTE: A long blowdown
exhaust hose can lengthen the blowdown time and also presents the possibility of blockage.
iii. The bulk abrasive blaster is provided with mounting holes in the bottom leg foot pad. These
holes can be used for securing the blaster to the floor or mounting structure.
3.2 Compressed Air Requirements (blast nozzle)
The blast nozzle size and blast pressure determines the compressed air requirements. Available
air flow capacity and/or air compressor size must be considered before selecting the blast
nozzle size. An air source dedicated to the abrasive blast system is preferred to reduce system
pressure drops and back flow of air. If an existing air compressor will be used or a limited air
supply is available, then the blast nozzle must be selected based on these conditions. Be aware
that as the blast nozzle wears the air demand will increase. See Table 1 in Section 13.0 for air
consumption by nozzle size at various pressures.
3.3 Air Compressor Size
Air compressor size is crucial to the operation of the abrasive blast system. Blast nozzle
selection and desired productivity must be evaluated to determine the air flow requirements
prior to selecting the air compressor size. Sufficient air supply capacity is necessary to maintain
the system air pressure. Insufficient air flow capacity will result in reduced blast nozzle pressure
and lost productivity. The air compressor must be large enough to supply:
i. The sum of blast air requirements for each nozzle at the highest pressure that will be
used (see Section 13.0, Table 1).
ii. The 12 CFM breathing air supplied to each blast operator respirator. NOTE: Reference
OSHA regulations regarding requirements for breathing air, especially when an oil-
lubricated air compressor is used.
