1.1. GENERAL RULE FOR SAFER OPERATION.
SCHMIDT® AIRPREP SYSTEMS HAVE BEEN DESIGNED TO BE SAFE WHEN USED IN
THE PROPER MANNER. ALL AIRPREP SYSTEMS ARE POTENTIALLY DANGEROUS IF
ALL SAFETY PRECAUTIONS ARE NOT RIGOROUSLY FOLLOWED. PROPER
TRAINING IS REQUIRED BEFORE OPERATION. PROPER PROCEDURES MUST BE
FOLLOWED. THE AIRPREP SYSTEM AND ALL COMPONENTS MUST BE PROPERLY
MAINTAINED. FAILURE TO OPERATE, SERVICE AND MAINTAIN THE AIRPREP
SYSTEM AS SET FORTH IN THIS MANUAL MAY CAUSE INJURY OR EVEN DEATH
TO ANY PERSON USING, SERVICING OR IN THE VICINITY OF THE AIRPREP
SYSTEM.
THIS MANUAL IDENTIFIES POTENTIAL HAZARDS BY DANGER, WARNING, AND
CAUTION SYMBOLS. HOWEVER, ALL THE RULES, PROCEDURES AND
RECOMMENDATIONS MUST BE FOLLOWED. FAILURE TO OPERATE PROPERLY IS
VERY LIKELY TO PLACE PERSONS AND PROPERTY AT HIGH RISK OF DAMAGE,
INJURY OR EVEN DEATH.
THIS EQUIPMENT IS DESIGNED TO BE USED IN CONJUNCTION WITH ABRASIVE
BLAST EQUIPMENT THEREFORE SOME OF THE RULES FOR SAFER OPERATION
THAT FOLLOW MAY NOT BE SPECIFIC TO THE USE OF THE AIRPREP SYSTEM
HOWEVER, OPERATORS MAY ENCOUNTER THESE POTENTIAL HAZARDS.
AIRPREP SYSTEMS AND THE ABRASIVE BLAST OPERATION ARE POTENTIALLY
DANGEROUS IF ALL SAFETY PRECAUTIONS ARE NOT FOLLOWED. FAILURE TO
OPERATE THE AIRPREP SYSTEM WITHOUT FOLLOWING ALL THE RULES FOR
SAFER OPERATION MAY RESULT IN SERIOUS INJURY OR DEATH TO OPERATING
PERSONNEL OR PERSONS IN THE OPERATING VICINITY.
1.2. KNOW YOUR EQUIPMENT.
Do Not operate this equipment in a manner other than its intended application (see Section 4.0).
Do Not operate this equipment or any other Schmidt® equipment without following the Rules
for Safer Operation and all the operating procedures and instructions. Learn the applications and
limitations as well as the specific potential hazards related to this machine. Failure to do so could
result in serious injury or death.
1.3. RECEIVE PROPER TRAINING.
Do Not operate this equipment unless you have received operational and maintenance training.
Begin by thoroughly reading and understanding this operation and maintenance manual and all
included information. Consult an authorized Schmidt distributor or Axxiom manufacturing, Inc.
1.4. PROTECT YOUR FEET.
Do Not operate this equipment without wearing OSHA approved foot protection. Observe all
applicable local, state and federal regulations. See Section 3.9 and OSHA 29 CFR 1910.136.
Heavy objects can shift while being blasted and may fall on operators. Wear foot protection to
prevent injury. See Section 3.9 and OSHA 29 CFR 1910.136.
1.0 Rules for Safer Operation

1.5. PROTECT YOUR EYES.
Do Not operate this equipment without wearing OSHA approved safety glasses. Observe all
applicable local, state and federal safety regulations. See Section 3.9 and OSHA 29 CFR
1910.133.
The abrasive blast operation produces a dusty work environment which can leave dust that can
be blown in the face and eyes of operators. Wear OSHA approved safety glasses. See Section 3.9
and OSHA 29 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 Section 3.9 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 Section 3.9 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 and therefore requires the use of a carbon monoxide
detector (See Section 3.9). 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. 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. Reference 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.

1.8. PROTECT YOUR HEARING.
Do Not operate this equipment without wearing OSHA approved hearing protection. Observe all
applicable local, state and federal safety regulations. See Section 3.9 and refer to OSHA 29 CFR
1910.95.
Loud noise is generated by the blast nozzle and the blowdown operation of this equipment. Wear
OSHA approved hearing protection. See Section 3.9 and OSHA 29 CFR 1910.95.
1.9. PROTECT YOUR PERSON
Abrasive blasting produces dust contaminated with toxic substances from the abrasive used, the
coating being removed, and the object being blasted. All blast operators and other personnel
involved in the blast operation or in the vicinity of the blast operation should wear protective
clothing. The protective clothing should be disposable or washable work clothes that should be
removed at the worksite so that contaminated dust is not transferred into automobiles or homes.
See Section 3.9 and OSHA 29 CFR 1910.94 and 1910.134.
1.10. ADHERE TO ALL REGULATIONS.
Do Not operate this equipment without observing all local, state, and federal safety regulations
including, but not limited to, OSHA (Occupational Health and Safety Administration).
1.11. STAY ALERT.
Do Not operate this equipment when you are tired or fatigued. Use caution and common sense
while operating and/or performing maintenance on this equipment.
1.12. DO NOT USE DRUGS, ALCOHOL, or MEDICATION.
Do Not operate this equipment while under the influence of drugs, alcohol, or any medication.
1.13. PROTECT BYSTANDERS.
Do Not allow blast equipment and related equipment operators and other personnel to enter the
vicinity of the blast operation without providing respiratory protective equipment that meets
OSHA regulations. If dust concentration levels exceed the limitations set in OSHA 29 CFR
1910.1000 then respirators are required.
1.14. KEEP CHILDREN AND VISITORS AWAY.
Do Not allow children or other non-operating personnel to contact this equipment or the
connecting hoses and cords. Keep children and non-operating personnel away from work area.
1.15. AVOID DANGEROUS ENVIRONMENTS.
Do Not operate this equipment without familiarizing yourself with the surrounding environment.
The blast operation and the use of this equipment create high level of noise which will prevent
the operator from hearing other possible dangers (i.e. traffic or moving equipment). In such
situations a stand-by watch person may be necessary to prevent injury to personnel.
1.16. AVOID DANGEROUS ENVIRONMENTS.
Do Not use this equipment in areas cluttered with debris. Debris in the work area can create
tripping hazards which can cause the operator to loose balance and result in injury to operating
personnel. Keep work area clean and well lit. When working at an elevated location, pay
attention to articles and persons below.
