18. Is dry ice blasting in an enclosed area possible?

Depending on the pellet rate set on the CRYONOMIC^® blaster, the cleaning process converts between 20 kg/hr and 105 kg/hr of solid pellets into CO₂-gas. This implies that adequate ventilation and proper fresh air supply has to be supplied to the operator and other personnel when cleaning to remain the CO₂ level below the MAK value of 0,5 % (5000 ppm or 9,1 g/m³) under all operating conditions.
When working in a sound enclosure it is recommended to use a CO₂ detector, which takes action when concentrations exceeding 3000 ppm CO₂ are detected (sound alarm, shut off equipment, etc.).
