Taking Extra Precautions on Sand Blasting A process wherein a fine granular sand is applied using high pressure against a rough surface to make it smooth is called sand blasting, or commonly known as “abrasive blasting”. The abrasive tool is being propelled in this process, it’s either with a liquid or gas, but it is most likely a pressurized air, with a use of a nozzle onto an uneven surface. Sand blasting is being applied on different surfaces in order to make it smooth, before the application of paint. The result will affect the number of ways that this procedure will take, it depends if it will satisfy you or not. The most commonly known process is a portable device which is sprayed on a large surface. If the operator will do this process, he needs to be extra careful and he must take extra precautions, for instance, he must not work on a confined area and also, he must wear a personal protective equipment which is commonly known as PPE. Some methods (such as wetblasting, or sand blasting using water) negate the risk of airborne contaminants, but pose another risk in the form of wastewater. There are also other materials like silica sand which is highly recommended to keep the risk down. Another method of sand blasting is called containment blasting. So in this procedure, the material that needs smoothening will be placed in an enclosed area where sand is being blasted to it then it is being recycled. The risk of weather conditions impacting the smoothing process is one of the benefits of this procedure, another is by reducing the risk of exposure to the operator. However, there is another alternative which is called the vacuum blasting. This method not only blasts, but recovers the abrasives both for recycling and for keeping the area clean of contaminants.

No matter what procedure the operator will use, he still needs to take extra careful and to follow rules rigorously and to the latter. In order to be safe, it must be reviewed on a regular basis and it should not be ignored just to get the job done.

The sand blasting method is really helpful in improving uneven surfaces, however it must be used properly to get rid of danger. It is really a must that operators should take extra hazards and must be mindful of the risk that can happen if the tools will not be used properly. Failure to abide by these safety guidelines could lead to both short term and long term health risks, such as lung problems, in the future. But if done properly it is a great tool to speed up an otherwise time consuming job.
