    Workers face significant risks from faulty abrasive blasting equipment, leading to extreme noise and hazardous quartz exposures exceeding permissible limits. This highlights critical safety gaps in the industry.

    Area of Science:

    • Occupational Health and Safety
    • Industrial Hygiene
    • Environmental Science

    Background:

    • Abrasive blasting is a common industrial process with inherent occupational hazards.
    • Previous studies have indicated potential risks, but a comprehensive national overview was lacking.

    Purpose of the Study:

    • To assess the current state of abrasive blasting practices nationwide.
    • To identify common equipment deficiencies and maintenance issues.
    • To evaluate worker exposures to noise and respirable crystalline silica.

    Main Methods:

    • Conducted a nationwide field survey of abrasive blasting operations.
    • Assessed equipment condition and maintenance logs.
    • Monitored noise levels and personal air samples for quartz (respirable crystalline silica).

    Main Results:

    • Widespread equipment deficiencies and poor maintenance practices were observed.
    • Workers were frequently exposed to extreme noise levels.
    • Respirable crystalline silica exposures were consistently above the Threshold Limit Value (TLV).

    Conclusions:

    • Current abrasive blasting practices pose significant health risks to workers.
    • Urgent improvements in equipment maintenance and exposure controls are necessary.
    • Regulatory oversight and industry-specific safety standards need reinforcement.
