Summary
Allergies to safety shoes were identified in 13 cases between 1972 and 1984, predominantly affecting young men. Unique allergens, including mercaptobenzothiazole, were found in the nonwoven materials of these shoes.
Area of Science:
- Occupational dermatology
- Materials science
Background:
- Allergic contact dermatitis is a common occupational hazard.
- Safety shoes are essential personal protective equipment in many industries.
Purpose of the Study:
- To investigate cases of allergy specifically linked to safety shoes.
- To identify the causative allergens in safety shoe materials.
Main Methods:
- Retrospective case review of allergic reactions reported between 1972-1984.
- Analysis of shoe materials for potential allergens.
Main Results:
- Thirteen cases of allergic reactions to safety shoes were documented.
- The identified allergens differed significantly from those found in conventional footwear.
- Mercaptobenzothiazole and dibenzothiazyl disulfide were detected in nonwoven shoe components.
Conclusions:
- Safety shoes can cause unique allergic contact dermatitis, primarily in young men.
- Mercaptobenzothiazole and related compounds in nonwoven materials are likely culprits.
- Further investigation into shoe material safety is warranted.
