Abrasive Blasting: Protecting Workers from the Hazards of Abrasive Blasting Materials Fact Sheet. (OSHA FS 3697 - 2014) (English: PDF )
Sandblasting is a process that has been around for decades. It's used to clean, etch, and prepare surfaces before painting or coating them with another material. Unfortunately, sandblasters are machines that produce high noise levels and dust that can be dangerous if not operated properly.
Dry blasting can be done with a siphon hose, which draws the media from a collection point, or a direct pressure system. Direct pressure dry blasting is faster and can utilize heavier particles (i.e., steel shot). However, it's not ideal for jobs where precision or detail work is necessary.
This Code provides guidance on managing the risks of abrasive blasting by following a systematic process that involves: · identifying hazards · if necessary, assessing the risks associated with these hazards · implementing control measures, and · reviewing control measures.
