What is Abrasive Blasting?
Abrasive Blasting is a common industrial process used to remove the surface coating from materials or structures to prepare them for final finishing such as painting, machining or assembly. The most common blasting method uses compressed air to propel abrasive material from a blast pot, through a blasting hose to a nozzle that is manually controlled by an operator.
Why is dust control important when Abrasive Blasting is undertaken?
Abrasive Blasting generates large volumes of respirable dust that can be toxic and small enough to be inhaled into lungs and thus can be hazardous to workers. Crystalline silica and lead are typical examples of toxic dusts that can be generated during abrasive blasting activities. Installing a quality dust collection system removes unsafe contaminants from the air and keeps the workplace safe for operators.
Where is Abrasive Blasting work undertaken?
Abrasive Blasting can be performed in open sites for example on buildings, bridges, tanks, dock yards etc or it can be performed within enclosed environments such as blasting chambers or cabinets or dedicated blast rooms.
What are Blast Rooms?
Blast rooms are typically sealed rooms where operators work inside to undertake blasting work. A dust collection system is used to filter the air in the room and prevent particulate matter from escaping. Blast rooms can be designed to any size to meet the requirements of the work typically undertaken.
