Screen printing workers experience significant health issues like headaches and fatigue due to high organic solvent exposure. Both short-term and long-term exposures often exceed recommended limits, highlighting workplace safety concerns.

Area of Science:

  • Occupational Health and Safety
  • Industrial Hygiene
  • Toxicology

Background:

  • Small screen printing companies often utilize organic solvents, posing potential health risks to workers.
  • Understanding exposure patterns and associated health symptoms is crucial for risk assessment and mitigation in this industry.

Purpose of the Study:

  • To comprehensively describe working conditions and organic solvent exposure patterns.
  • To investigate the relationship between solvent exposure and related health symptoms among screen printing workers.
  • To evaluate the contribution of short-term peak exposures to overall time-weighted average (TWA) exposures.

Main Methods:

  • Utilized continuous area monitoring, grab sampling, personal sampling, and time study observations.
  • Monitored 27 workers for solvent exposure and characterized short-term peak exposures.

  • Administered a health questionnaire to assess symptoms potentially attributable to solvent exposure.

    • Main Results:

    • Exposed workers reported significantly higher prevalence of headaches, dizziness, intoxication, and dry skin (p < 0.01).
    • Increased likelihood of fatigue, reduced arm/hand strength, concentration difficulties, sore throat, and low alcohol tolerance in exposed workers.
    • Documented highly variable TWA exposures (2%-100% of TLV) and routine exceedances of STELs, with frequent skin contact observed.

    Conclusions:

    • High short-term solvent exposures significantly contribute to overall TWA exposures in screen printing.
    • Routine exceedances of STELs and frequent skin contact indicate inadequate exposure control.
    • Complex exposure patterns likely contribute to the observed health problems in this industry.
