Summary

Home use of low-concentration hydrofluoric acid can cause severe skin burns and necrosis. Prompt treatment with calcium compounds is crucial to prevent hypocalcemia and manage these dangerous household chemical injuries.

Area of Science:

  • Toxicology
  • Dermatology
  • Emergency Medicine

Background:

  • Hydrofluoric acid (HF) is a widely used industrial chemical.
  • HF exposure can lead to severe chemical burns and potentially life-threatening hypocalcemia.
  • Household products containing HF pose a significant, often underestimated, risk.

Observation:

  • A case of a 57-year-old woman with severe hand burns and skin necrosis after using a homemade furniture cleaner with 5% HF.
  • Initial presentation showed edema, erythema, and severe pain.
  • Despite initial treatment with calcium chloride, necrotic lesions developed on the fingers.

Findings:

  • Hydrofluoric acid causes delayed-onset caustic burns.
  • HF exposure can lead to hypocalcaemia due to calcium fluoride precipitation.

  • The risk of hypocalcaemia is proportional to the area of skin exposed.

    • Implications:

    • Household use of HF-containing products requires extreme caution.
    • Early and aggressive treatment, including calcium administration and wound care, is vital for managing HF burns.
    • Close monitoring of serum calcium levels is essential in patients with significant HF exposure.
