Electrostatic Discharge
Safety Precautions
Safety
Electrostatic discharge can be hazardous to the operator and the
equipment. The static charge of CO
2
varies with the amount of ice and
humidity present. Follow these instructions to assure safe operation while
blasting.
A) The power outlet must have a good ground
This is critical for electrostatic dissipation. If the ground is not
connected a charge will build up on the unit or the applicator. As a
secondary backup the unit's electrically conductive wheels will help
bleed off any additional static charge.
B) The blasting unit’s static ground cable must be attached to the
target surface
If a target is on a non-grounded surface it will build up an electrostatic
charge, which could injure the operator or damage the equipment.
Wrap or clip the static ground cable to the target to dissipate the
charge. Metal framing, that holds the target in place, can be used but
the target and frame must be electrically connected. Use a conductivity
tester for confirmation.
C) Know your environment
Electrostatic buildup changes as humidity levels change and will vary
by location. Electrostatic discharge is higher at low humidity levels and
occurs most often during cold weather.
