Traditional blasting methods require a long list of equipment, both to perform the task and to minimize the operator’s exposure to hazards (utilizing Personal Protection Equipment – “PPE”). Equipment requirements include an air compressor (either gas/diesel or electric) to propel the sand/beads, hoses, bags of sand, a protective suit, gloves, goggles, hearing protection and respirator/helmet for the operator. Abrasive blasting operations create high levels of noise leading to hearing loss, and dust, including silica sand (crystalline), which can cause silicosis, lung cancer, and breathing problems in exposed workers.
Abrasive blasting operators are also at risk of heat-related illnesses due to the PPE (blast helmets and protective suits) that is worn sometimes for long periods of time, the work activity or physical demands of the job, and environmental conditions (i.e., temperature, humidity, and air movement).
