Containment for Dry Ice Blasting
We build containments for various reasons
- This is to protect the health of all working and or exposed to the blasting area. Blasting displaces the debris, film, build up, resin, and whatever else is on top of the substrate to be cleaned. Displaced means it is blasted with dry ice. It goes somewhere. First into the air, then settles dependent upon weight and density after blasted.
- The containment helps protect those near the blasting area from being hit with particles,, pieces, and chunks. Think of the containment as a large, coop of safety goggles for all on the exterior. We wear safety goggles and face shiels, so we know the rest of the work environment is to be protected as well.
- As part of many containments, we add custom negative air and filtering. This traps and filters the particl count of the material removed. In doing so, it reduces the settlement of the lighter, smaller debris removed. It is one more step of cleaning up while the cleaning from dry ice blasting occurs. This reduces what is being put into the air and what will affect the respiratory systems of all exposed to the working area. This goes back to the importance of both IAQM and the staff of the worksite to know the exact chemical / material make up of what is to be removed from the substrate when blasting.
- This is a must when working in confined spaces. The blasting puts CO2 into the space, discpacing the oxygen level. We force air into the space. At the same time, we create a negative air system to pull out blasted particle count along with the CO2.

The Green and Eco-friendly Dry Ice Blasting
Why destroy Mother Earth when we don't have to?
So many clean with chemicals. How is this really cleaning when harmful fumes and off gassing occur? The chemical goes somewhere. So enters blasting for speed and a higher quality clean.
There are multiple medias to blast with from sand to soda, and everything you can think of in between.
All blasting methods will displace and leave behind a socondary waste... all but one. These secondary wastes left behind are the blasting media; crushed glass, baking soda, walnut shell, silica sand or crystalline, dry ice, among others.
Silica sand(crystalline) can cause silicosis, lung cancer, and breathing problems to exposed areas to human, bird, aquatic, and animal life.
Crushed glass is exactly that, crushed glass with water added. This creates an obvious runoff.
Soda blasting uses baking soda as the media. This is very effective in mold and fire remediation. The problem is the soda when blasted creates a large cloud of dust, soda dust. This then settles in the surrounding work area. Baking soda settled on plants will kill the vegetation and landscaping. The dust will eventually runoff with watering amd rain. This contaminates and risks the nearby aquatic life and systems.
Dry ice blasting is the only blasting media and method which does not leave behind a secondary waste. It does not create a runoff exposing and risking human health, aquatic life, water ways, plant, and animal life.
Dry ice blasting is EPA & FDA approved cleaning. It requires proper PPE. OSHA describes dry ice blasting as "Alternative, less toxic blasting material" under the "OSHA Fact Sheet: Protecting Workers from the Hazards of
Abrasive Blasting Materials".
The CO2 is in solid, frozen form as a media. Upon impact from blasting with forced air, the CO2 returns to gas and disipates, leaving behind zero secondary waste to clean up, or risk to the environment.
