Three Precautions for Dry Ice Blasting for Equipment Surface Cleaning

Posted on: 7 July 2021

If the surfaces of your industrial or commercial machinery are covered in dirt, grime and rust, use dry ice blasting as your cleaning method. This technique is ideal because of its minimal adverse effect on both the equipment and the user. As implied, dry ice blasting uses pellets of solidified carbon dioxide. These units are released at a high velocity as abrasive blasting media when cleaning.

Unlike traditional sandblasting, this medium is gentle on surfaces. Moreover, the ice becomes vapour after contact with the surface, eliminating the need for media recovery. Dry ice blasting also minimises the use of chemical cleaners that are bad for the environment and dangerous to users. If you are interested in using this method, consider the outlined guidelines for the best results.

Use Protective Wear

When using dry ice, maintain caution to avoid personal injury. In general, dry ice is not highly hazardous, but the low temperature can cause significant harm. Therefore, avoid prolonged direct exposure to the dry ice during the cleaning project. Also, consider using protective wear such as gloves, safety, goggles and coveralls during the work. The protective wear will shield against potential accidents in case of poor equipment use, machinery malfunction and other accidents.

Inspect the Equipment

The pellets used in dry ice blasting are accelerated through the use of pressurised air. If the blasting equipment for your project is not in good condition, the pressurised air stream can be dangerous. The pellets could be released incorrectly, leading to personal injuries. Also, your industrial or commercial equipment could sustain damage from the faulty equipment. Therefore, make sure that the blasting machinery is in good condition before beginning the cleaning tasks. Look out for signs of unit damage like dents, tears and components looseness. Moreover, avoid working with kinked hoses.

Check the Technique

Finally, consider the best techniques for dry ice blasting before beginning the task. The right approach will maximise the benefits of the surface cleaning process. The most critical consideration for ideal blasting is consistency. In simple terms, keep the release of the dry ice pellets smooth and stable. Do not change the distance between the nozzle and the surface. Otherwise, the final appearance will be varied. Also, keep an eye on your spray pattern. Do not make multiple overlaps when blasting. A high overlap could stress the equipment surface due to repeated blasting. Moreover, minimal overlap will mean improved time and cost-efficiency.
