    Area of Science:

    • Industrial Hygiene
    • Aerosol Science
    • Occupational Safety

    Background:

    • Paint spray respirators require standardized aerosol testing for effective evaluation.
    • Current testing methods may not adequately represent real-world paint aerosol conditions.
    • Aerosol characteristics are influenced by liquid properties, nozzle flow, and droplet evaporation.

    Purpose of the Study:

    • To develop a reliable technique for controlling paint aerosol concentrations.
    • To characterize particle-size distributions of different paint types.
    • To assess the impact of aerosol variations on respirator filter performance.

    Main Methods:

    • Liquid paint was atomized using a spray nozzle to generate aerosols.
    • A novel technique was implemented for consistent aerosol concentration control.
    • Particle-size distributions for lacquer and enamel paints were measured.
    • Aerosol concentration gradients and their effect on filter loading resistance were analyzed.

    Main Results:

    • A reliable method for controlling aerosol concentrations was successfully developed.
    • Lacquer paint aerosols exhibited a multi-modal particle-size distribution.
    • Improper nozzle positioning led to significant aerosol concentration gradients.
    • Filter loading resistance was found to be sensitive to aerosol concentration variations.

    Conclusions:

    • The developed technique offers reliable control over paint aerosol generation for testing.
    • Particle-size distribution is a critical factor in respirator aerosol testing.
    • Current NIOSH criteria for respirator testing should be enhanced.
    • Recommendations include specifying particle-size distribution, paint composition, and concentration ranges for improved testing standards.
