Delayed dermal burns caused by dimethyl acetylenedicarboxylate.

A J Slovak, A R Payne

    Contact Dermatitis
    |July 1, 1984
    PubMed
    Summary

    Dimethyl acetylenedicarboxylate (DMAD) can cause delayed, painless skin burns. Even dilute solutions are hazardous, penetrating protective gear and offering inadequate warning of exposure risks.

    Area of Science:

    • Chemical safety
    • Occupational health
    • Dermatology

    Background:

    • Dimethyl acetylenedicarboxylate (DMAD) is a chemical reagent used in various industrial applications.
    • Assessing the occupational hazards associated with DMAD exposure is crucial for worker safety.

    Observation:

    • A chemical operator experienced delayed, pain-free burns on his foot two days post-DMAD spillage.
    • Chemical analysis confirmed DMAD presence on the operator's safety boot, linking it to the injuries.

    Findings:

    • DMAD can penetrate certain types of protective clothing.
    • Dilute solutions of DMAD pose a significant risk of skin damage.
    • The toxic effects of DMAD are insidious, characterized by a delay in symptom onset and lack of pain, making early detection difficult.

    Implications:

    • Standard personal protective equipment may not offer sufficient protection against DMAD.
    • The delayed and painless nature of DMAD-induced burns necessitates heightened awareness and improved safety protocols in handling this chemical.
    • Further research into DMAD's toxicological profile and effective decontamination procedures is warranted.
