Abrasive Blasting & Coatings Removal - Negative Pressure, Ventilation, Dust & Debris Control

Potential exposure to hazardous dust and air contaminants is a primary health hazard associated with abrasive blasting. Abrasive blasting can generate large quantities of dust that can contain high levels of toxic air contaminants including but not limited to, silica, asbestos, lead, vinyl chloride, inorganic arsenic, benzene, chromium, cadmium and many more.

Abrasive blasting is the most common surface preparation technique used to remove old paint, coatings and other surface materials such as rust, mill scale, dirt, and salts during maintenance and repair operations on ship, bridges, tanks and other structures. According to OSHA, surface cleaning and preparation techniques, such as abrasive blasting, are also one of the most significant sources of shipyard wastes and pollution.

In abrasive blasting, compressed air is used to propel abrasive material through a blasting hose to a nozzle, where it is directed to the work area at high velocity by the operator. Air pressure is typically high and abrasive blasting operations can expose employees to many toxic air contaminants.
