FactSheet
Protecting Workers from the Hazards of
Abrasive Blasting Materials
Abrasive blasting uses compressed air or water to direct a high velocity stream of
an abrasive material to clean an object or surface, remove burrs, apply a texture, or
prepare a surface for the application of paint or other type of coating. Employers
must protect workers from hazardous dust levels and toxic metals that may be
generated from both the blasting material and the underlying substrate and coatings
being blasted. This fact sheet provides information on abrasive blasting material,
health hazards, and methods to protect workers.
Abrasive Blasting Materials
The decision to use a certain type of abrasive
material can depend on factors such as cost, job
specifications, environment, and worker health.
Commonly used abrasive materials:
• Silica sand (crystalline)
• Coal slag
• Garnet sand
• Nickel slag
• Copper slag
• Glass (beads or crushed)
• Steel shot
• Steel grit
• Specular hematite (iron ore)
Alternative, less toxic blasting materials include:
• Ice cubes
• Dry ice
• Plastic bead media
• Sponge
• Sodium bicarbonate (baking soda)
• Ground walnut shells, ground corn cob and
other biodegradable materials
• High pressure water
Health Hazards
Abrasive blasting operations can create high
levels of dust and noise. Abrasive material
and the surface being blasted may contain
toxic materials (e.g., lead paint, silica) that are
hazardous to workers.
• Silica sand (crystalline) can cause silicosis,
lung cancer, and breathing problems in
exposed workers.
• Coal slag and garnet sand may cause lung
damage similar to silica sand (based on
preliminary animal testing).
• Copper slag, nickel slag, and glass (crushed
or beads) also have the potential to cause
lung damage.
• Steel grit and shot have less potential to cause
lung damage.
• Slags can contain trace amounts of toxic metals
such as arsenic, beryllium, and cadmium.

**** CAUTION ****
Abrasive blasting creates high levels of
noise that can cause substantial hearing
loss. Always wear hearing protection.
Employers must administer a hearing
conservation program as required by the
OSHA Occupational Noise standard.

How to Protect Workers from Exposure
to Abrasive Blasting Materials
Each abrasive blasting operation is unique,
involving different surfaces, coatings, blast
material, and working conditions. Before
beginning work, employers should identify
the hazards and assign a knowledgeable
person trained to recognize hazards and
with the authority to quickly take corrective
action to eliminate them. Use engineering and
administrative controls, personal protective
equipment (PPE), including respiratory
protection, and training to protect workers
involved in abrasive blasting activities.
Engineering controls, such as substitution,
isolation, containment, and ventilation are
the primary means of preventing or reducing
exposures to airborne hazards during abrasive
blasting operations. Administrative controls,
including the use of good work and personal
hygiene practices, can also reduce exposure.
When engineering and administrative controls
cannot keep exposures to hazardous materials
below OSHA permissible exposure limits,
respiratory protection must be used.
Engineering Controls
1. Substitution
• Use a less toxic abrasive blasting material.
• Use abrasives that can be delivered with
water (slurry) to reduce dust.
2. Isolation and Containment
• Use barriers and curtain walls to isolate the
blasting operation from other workers.
• Use blast rooms or blast cabinets for smaller
operations.
• Use restricted areas for non-enclosed blasting
operations.
• Keep coworkers away from the blaster.
3. Ventilation
• Use exhaust ventilation systems in
containment structures to capture dust.
Administrative Controls
Perform routine cleanup using wet methods
or HEPA filtered vacuuming to minimize the
accumulation of toxic dusts.
• Do not use compressed air to clean as this will
create dust in the air.
• Clean and decontaminate tarps and other
equipment on the worksite.
• Schedule blasting when the least number of
workers are at the site.
• Avoid blasting in windy conditions to prevent
the spread of any hazardous materials.
Personal Hygiene Practices
• Prohibit eating, drinking, or using tobacco
products in blasting areas.
• Provide wash stations so workers can wash
their hands and face routinely and before
eating, drinking, or smoking.
• Vacuum or remove contaminated work
clothes before eating, drinking or smoking.

OPERATION
Little Blaster™
1. Preparing Parts for Blasting :
All parts to be processed must be free of oil, grease, and moisture. Make
sure parts are dry before putting into cabinet for processing.
2. Air Pressure :
Set air pressure at 40 ~ 80 PSI. Most parts for blasting should be blasted at
80 PSI. Designate parts to be processed, start at lower pressure, and work up
the PSI scale to obtain desired finish.
DO NOT CONNECT TO HIGH PRESSURE BOTTLE GAS, RUPTURE AND
EXPLOSION CAN OCCUR.
3. Gun Angle and Distance:
Direct blast at part with an approximate (45-60) degree angle
with ricochet toward the back side of cabinet. Do not hold at
90 degree to part being processed. This will cause the media to
blast to bounce back into the blast stream and slow blasting
action. Also 90-degree angle will cause excessive wear on gun
and viewing window. Hold gun approximately 6 inches from
part being cleaned.
GUN MUST ALWAYS BE POINTED AWAY FROM THE OPERATOR AND
TOWARD ITEM BEING PROCESSED. NEVER BLAST WITH ANY OF THE
CABINET DOORS OPEN. WHILE LOADING AND UNLOADING, NO ONE
SHOULD BE AT THE OPERATOR STATION AT FRONT OF THE BLAST
CABINET.
4. Media :
Media should be good quality and dry. Damp media will cause the media
not to flow and will clog abrasive flow.
Media Available @ Blast-It-All Online Store
IF YOU ARE HAVING A PROBLEM SELECTING MEDIA FOR A SPECIFIED JOB,
CONTACT YOUR DISTRIBUTOR FOR THEIR RECOMMENDATIONS

After installing the Dust Collector, it is very IMPORTANT to follow the next steps. This will ensure your
machine will blast satisfactorily and have good visibility in blast chamber.
1. Remove RED nuts securing the motor
housing and cartridge holder to dust
collector body. (Item 1) Discard these
nuts, they are not used.
2. Loosen nuts on back corners. Loosen until
the nut is to the bottom on the bolt
thread. This will allow the motor housing
and cartridge holder to rest securely on
the gasket seal.

3. To clean cartridge: Turn Dust
Collector switch off. Grasp lift handle
and raise up and down vigorously
allowing the top housing to thump on
the body lip. Do this repeatedly, until
loose dust on the cartridge falls off
into the dust sump. This should be
done every 30 minutes of blasting, or
each time before use. It is a good
idea occasionally to remove motor
housing and with 10-15 PSIof airline
pressure from air nozzle, blow the
cartridge pleats clean.
4. After thumping the cartridge, the drain
cap should be removed and the dust
emptied from dust collector sump into a
box, bag or container, for ease of
disposing.
Maintained properly, you will enjoy the performance of this reliable type dust collector.

TROUBLSHOOTING
1. Caking of Media :
A. Media caking is caused by moisture in compressed air supply or
oily and greasy parts. If this is not corrected, media will not flow
and will clog gun. Check air supply. If water or moisture is present,
install a good moisture trap. If oily or greasy parts are being blast
treated, you should first degrease and dry parts.
B. If blast gun should occasionally clog, tightly seal the front of the
nozzle against the inside front the blast cabinet and push foot
valve down 3 to 4 seconds. This will cause the system to back blast
through the gun and media hose and clear the media hose.
2. Gun Air Pressure Drop :
Set air regulator at 80 PSI on air gauge. Push foot valve and if
gauge reading should drop, check the air supply pipe or hose. A
restriction in the supply line such as reducers or quick couplers will
cause pressure drop. Also, if the blast cabinet is too far from the
air compressor, a pressure drop can occur. We recommend 1/2" -
1" I.D. air supply line. The bigger the better.
3. Poor Visibility - Excessive Dust :
A. Cabinet Air inlet blocked, check for blockage.
B. Dust collector sump full and needs emptied.
C. Cartridge contaminated. Clean by pushing up and down.
D. Media breakdown - replace media and clean dust collector.
4. Poor Media Flow :
A. Wet or damp media caused from moisture or oil in compressed air
line.
Use dry air or install a moisture filter.
B. Replace media and clean media sump and hose.
C. Media level should be below media screen.
D. Hole in media hose from wear, replace hose assembly.
E. Poor Air Flow/CFM
F. Worn Gun Body, Nozzle or Orifice

MAINTENANCE
1. Blasting Gun :
After 10 - 12 hours of blasting time the air
orifice and nozzle should be checked. If
the nozzle shows wear, rotate 1/4 Turn to
prevent uneven wear. If this is not
checked, it could result in the destruction
of nozzle and damage to the gun housing.
If wear is detected on the orifice tip,
replace.
2. After thumping the cartridge, the drain
cap should be removed and the dust
emptied from dust collector sump into a
box, bag or container, for ease of
disposing.
