Summary

Self-defense sprays containing CN and CS tear gases cause skin irritation and allergic reactions upon direct contact. Accidental exposure can lead to severe dermatitis, edema, and secondary infections requiring medical treatment.

Area of Science:

  • Dermatology
  • Toxicology
  • Occupational Health

Context:

  • Increasing availability and use of self-defense sprays and riot control agents.
  • Documented rise in cutaneous injuries linked to these chemical agents.
  • Focus on chloracetophenone (CN) and orthochlorobenzylidene malononitrile (CS) tear gases.

Purpose:

  • To describe the clinical effects of self-defense sprays and tear gases on the skin.
  • To differentiate between experimental and accidental exposure outcomes.
  • To highlight the potential for irritant dermatitis, eczema, and allergic sensitization.

Summary:

  • CN and CS are insoluble in water and commonly used in aerosolized self-defense sprays.
  • Direct skin contact causes severe irritation, erythema, and vesicles, exacerbated by humidity.

  • Accidental exposure results in a two-stage reaction: initial irritation followed by edema and potential infection, with recovery taking 10-15 days.

    • Impact:

    • Tear gases can act as potential allergens, leading to sensitization after repeated exposure.
    • Accidental exposure can cause significant skin lesions resembling Quincke's edema.
    • Understanding these effects is crucial for medical treatment and prevention strategies.
