Dry ice blasting
reduces or eliminates employee exposure to (and your companies
liability from) the use of dangerous chemical cleaning agents.
Dry
ice blast cleaning is quickly establishing itself as a favored method of
cleaning in mold remediation (mold removal) and is superior to cleaning
mold compared to traditional labor-intensive techniques such as sanders,
scrapers and wire brushes. The dry ice process cleans as thoroughly or
more so and in dramatically less time. Also, compared to soda blasting,
dry ice blast cleaning is as fast and creates far less mess.
Dry ice blasting can
also be used to clean food processing equipment to effectively
decontaminate surfaces of Salmonella enteritidis, E.coli, and Listeria
monocytogenes such that these microorganisms are not detectable using
conventional microbiological methods. It may also be used to clean some
equipment without disassembly and without producing fire or electrical
hazards. The EPA recommends dry ice blasting as an alternative to many
types of solvent-based cleaning. Dry ice blasting can clean numerous
objects with differing, complex geometries at once.
Though not toxic, carbon dioxide can
displace oxygen resulting in asphyxia if equipment is not used in a
ventilated area. In addition, because carbon dioxide is heavier than
air, exhaust vents are required to be at or near ground level to
efficiently remove the gas. At normal pressure dry ice is −78 °C (−108.4
°F) and must be handled with insulated gloves. Eye and ear protection
are required to safely use dry ice cleaning equipment. Compared to other
blasting-cleaning methods, dry ice blasting produces fewer waste
products and does not require clean-up of a blasting medium.
