Working with the Abrasive Media
(cont’d)
√
Certain abrasive media, such as glass beads, can present a
slipping hazard if they are spilled on the ground. Always clean up
spilled abrasive and place appropriate warning signs in areas
where the abrasive will be on the ground (such as during long-
term operation).
√
Abrasive powders, particularly glass beads and plastic, may
generate static charges. To minimize the risk of electrostatic
discharge, ground the MicroBlaster and the workstation. In some
instances, the operator may also wish to use grounding straps
(Wrist-
Stats™ or equivalent).
√
Flammable powders, such as walnut shell and plastic, may pose a
fire or explosion hazard. Always use a vigorous dust extraction
device to prevent hanging dust clouds.
√
After using the MicroBlaster, or after handling any of the abrasive
media, wash your hands before touching or rubbing your eyes.
√
Gloves may be necessary for operators who are sensitive to
powders or dust on their skin.
√
Some powders, if allowed to collect inside the machine, may
cause electrical shorts.
√
Abrasives cause wear to virtually every surface they come in
contact with. Keep the threads on the tank and tank cover clean
of abrasive powder to avoid wear that can cause a dangerous
condition. See Section 4 for details on how to check for tank cover
wear. Also, always fill the tank through the flapper valve to greatly
reduce the amount of wear on the threads.
Material safe
ty data sheets (MSDS’s) for all abrasives distributed by Comco are
available from the Comco factory. Every powder shipment includes an MSDS.
Contact the Comco Customer Service department to obtain extra copies of any
MSDS.
Avoiding Hazards Associated with Operating Machinery
√
Place the MicroBlaster securely on a solid workbench or counter
so that the unit cannot tilt or fall over.
√
Always secure the nozzle-end of the abrasive blast hose before
pressurizing a blasting unit. An unsecured hose may whip around
and cause injury or damage.
√
Keep fingers out of the hose pinch.
√
When working inside the cabinet, avoid possible sharp edges and
remember that solenoids on valves can become hot.
√
Set up the MicroBlaster and workstation so that it is ergonomically
correct to allow safe and comfortable use by all operators.
√
Route the foot pedal cord from behind the bench to prevent it from
becoming a possible trip hazard.
√
When refilling the tank, set the tank cover flat on its end to avoid it
rolling off the bench.
