PRECAUTIONS DURING BLASTING
Air, CO
2
gas and dry ice pellets leave the gun nozzle at a very
high velocity (up to 300 m/s - 984 ft/s).
Therefore:
• do not aim the nozzle at a person(s) or in the direction of a
place(s) where other people work,
• remember, dry ice pellets can be deected back from the
object being cleaned,
• do not aim the nozzle in directions where damage might
result. Do not use the machine “for fun” and under no
circumstances should you aim the gun nozzle at persons
or other living creatures.
STATIC ELECTRICITY
Serious discharge of static electricity can occur. Always
make sure that objects to be cleaned are adequately
earthed/grounded and that this earthing/grounding remains
stable throughout the whole cleaning process. The dry
ice blasting machine is earthed/grounded, from machine
cabinet to blasting gun, and through the main electricity
connection on the rear side of the machine – provided that
the machine has been set up and connected as described
under “Starting the Dry Ice Machine” on page 16.
PACEMAKER PRECAUTIONS
Do NOT use the dry ice blasting machine if you are wearing
a pacemaker. The dry ice blasting machine may cause
pacemaker malfunction.
EXPLOSIVE HAZARD
The machine must never be used in surroundings where
there is a danger of explosion. Despite optimum earthing/
grounding of both machine and cleaning object, static
electricity can be generated and create a spark.
