Safety Concerns: • Heavier than air makes it an asphyxiation hazard.


• Pressure: High pressure side operates at 1305 PSIG versus R-22 at 180 Pounds Per Square Inch Gauge (PSIG). Floor pressure under the ice at 363 PSIG versus R-22 direct systems at 25 PSIG.


• Trapped liquid between valves and fittings create extremes in pressure and potential rupture of vessels.


• Dry ice formation can block vent lines eliminating safety relief capabilities.


• Causes freeze burns when in contact as dry ice formation temperatures are minus 109.3
