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 DirectFlo 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 DirectFlo, 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.
Material safety 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 DirectFlo 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 DirectFlo 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.
