Are you new to sandblasting or still planning to invest in one for your workshop? You probably are having thoughts if sandblasting is dangerous or not. This is normal. It is always suggested that you check everything and see if the coast is clear before diving into something you have not experienced before and that includes sandblasting.
Sandblasting is basically a manner of blasting off surfaces with the use of compressed air that feeds the sandblasting gun to blow off the abrasive. High amount of air pressure is present from the compressor up to the sandblasting gun. Hence, safety measures should be strictly applied. If you will work around sandblasting, you should consider the following cons and workarounds:
Exposure to silica in sandblasters is very dangerous. Silica used in sandblasting creates very small dust particles that when exhaled, it penetrates the chambers of the lungs and develops fibrous tissues that can fill up the lungs. This disease is called Silicosis and is untreatable. As a workaround, use of proper protective equipment including masks is strongly advised. This is why industries that use sandblasting still get the advantage of using this method because every operator is properly protected.
Sandblasting requires high air pressure generated within the compressor. This high amount of compressed air can cause severe injuries to the person performing the sandblasting. This can be avoided if the quality of air tool like the sandblaster, compressor and air lines are checked prior to use. Equipment calibration is highly-urged to make sure that it functions properly without causing any issues. Filtering the air and making clear that only pure compressed air is used all throughout the sandblasting process to avoid blockage and pressure build up that can blow up any sections of the compressed air system.
