Q  Is dry ice blasting environmentally friendly?
A
  Yes, when we inhale our bodies use the oxygen in the air and we exhale CO2.  Green plants take CO2 from the air and give off oxygen.  Dry ice blasting is the most environmentally friendly cleaning method available today.

Q  Can dry ice blasting be done on plant equipment and machinery while it is in operation?
A
  In many cases Glacier Blast Inc. is able to do the dry ice blasting while the equipment is running.

Q  Will dry ice blasting leave behind a secondary waste stream?
A
  No, dry ice blasting has no secondary waste stream.

Q  Is dry ice blasting abrasive?
A
  No, dry ice blasting is not abrasive.  If you have a polished metal surface prior to blasting, it will still be polished after the dry ice blasting is done.  Dry ice blasting is a cleaning process, there is no blast profile left on metal or glass surfaces like there is with abrasive blasting methods.

Q  Will this process sterilize while it cleans?
A
  Yes it will, dry ice is -109 degrees Fahrenheit, at this temperature dry ice blasting kills bacteria.

Q  Are there hazards associated with dry ice blasting?
In a well ventilated area, there are the typical hazards associated with any type of industrial blasting, high noise levels, airborne particles and dust.  These hazards are eliminated with proper personal protective equipment.

A  In a confined space or poorly ventilated area one must remember that additional precautions are required.  Even though dry ice blasting is safe and environmentally friendly, the important thing to remember is that we do not want our breathing air oxygen content to drop below 19.5%.  CO2 added to any non-ventilated volume of air will displace the oxygen in the air.  In conditions such as these added ventilation and air monitoring equipment are needed.

Q  Are Glacier Blast employees certified to work in confined space?
A
  Yes, our dry ice blasting employees are OSHA certified to work in confined space applications.

Q  Does Glacier Blast provide all of the equipment required to complete a dry ice blasting project?
A
  We can provide all of the equipment needed to accomplish your dry ice blasting project.  This includes dry ice blasting, ventilation, air monitoring, respirators (includes SABA respirators if needed) and other personal protective equipment.

A  We also provide our customers with the option to use their own pressurized air and ventilation if they are adequate.
