Follow local governing codes to ensure a minimum standard of safety.
y
Wear protective gloves, eye protection and hearing protection along with any further PPE
recommended by the manufacturer of the abrasive media.
y
Operate the machine in a well-ventilated work area.
y

CO
2
Safety
This system uses dry ice (CO
2
in solid form). The temperature of dry ice is -109°F (-78.9°C). Avoid
coming into direct contact with dry ice as it may cause severe tissue damage.
Study the material safety data sheet (MSDS) of dry ice (CO
2
) supplied with the delivery of dry ice and
follow all the recommendations and guidelines listed therein.
Operate the blaster in a well-ventilated work area with continuous CO
2
-level monitoring. The effects
of CO
2
are entirely independent of the effects of oxygen deficiency. Therefore, CO
2
concentrations
at 3-5% causes headaches, fast breathing and discomfort while higher concentrations may cause
unconsciousness, suffocation or respiratory arrest. The legal exposure limit set by OSHA is a 0.5%
average over an 8-hour workday and the acute (15 minute) exposure limit set is 3.0%.
ALWAYS use a CO
2
monitoring/alarm system when working with machinery that emits CO
2
in a
confined room/space.
Electrostatic Discharge
Dry ice blasting may create electrostatic discharge(s). The blaster machine is fitted with effective
electrostatic dischargers to prevent injury or damage. Also, the blaster machine must be plugged
into a properly grounded electrical outlet.
It is recommended to avoid operating this equipment near explosive or flammable material. Also,
use a plastic shovel when handling dry ice to eliminate any additional static electricity.
