Occupational asthma can be caused by ethanolamines, commonly found in industrial fluids. Three cases highlight the link between workplace exposure to triethanolamine and monoethanolamine and the development of work-related asthma.

Area of Science:

  • Industrial Hygiene
  • Occupational Medicine
  • Toxicology

Background:

  • Amino alcohols, including ethanolamines, are widely used industrial chemicals.
  • While generally considered safe, they can cause local skin irritation at high concentrations.

Observation:

  • Three cases of occupational asthma linked to ethanolamine exposure are presented.
  • Two metal workers exposed to cutting fluid (triethanolamine) and one cleaner exposed to detergent (monoethanolamine) developed asthma.
  • Diagnosis was confirmed by work-related symptoms and chamber challenge tests.

Findings:

  • Occupational asthma was definitively linked to specific ethanolamines in the workplace.
  • Symptoms persisted even after cessation of exposure in all reported cases.

  • Ethanolamines should be considered potential respiratory sensitizers in occupational settings.

    • Implications:

    • Highlights the risk of occupational asthma from commonly used industrial chemicals.
    • Underscores the importance of proper ventilation and personal protective equipment in handling ethanolamine-containing products.
    • Suggests further investigation into the respiratory effects of ethanolamines in occupational environments.
