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 deflected 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 crea-
tures.
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 BLASTING MACHINE page
15.
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.
