Cold Jet 2A0388, Operator'S Manual

Page: 14 / 28

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 discharges. This machine is fitted with effective
electrostatic dischargers to prevent injury or damage. Also, the machine must be plugged into a
properly grounded electrical outlet.
It is recommended to avoid operating the machine near explosive or flammable material. Also,
use a plastic scooper when handling dry ice pellets to eliminate any electrostatic discharge.
