How dust is reduced
Dust can be reduced by wetting, wet abrasive blasting, extraction, enclosure or media-recovery systems. OSHA notes that an airborne-dust hazard can remain after water from wet blasting evaporates.
Capturing the waste
The mixture of water, abrasive and removed coating is waste that must be captured. Media can be recycled only in a system designed for it and with contamination taken into account. Proper protection also includes exposure assessment or monitoring and appropriate PPE.
