Dermal exposure to dilute hydrofluoric acid (HF) products is common, often due to safety failures. Topical calcium gluconate gel may effectively treat HF burns, with earlier application leading to faster healing.

Area of Science:

  • Toxicology
  • Dermatology
  • Consumer Product Safety

Background:

  • Dilute hydrofluoric acid (HF) in consumer products poses a dermal exposure risk.
  • Consumer misuse of safety procedures is a significant factor in HF exposures.

Purpose of the Study:

  • To evaluate the toxicity of dilute HF in consumer products.
  • To assess the efficacy of topical calcium gluconate gel for HF dermal exposure.

Main Methods:

  • Retrospective review of 237 cases of dermal exposure to HF rust removers.
  • Analysis of reported symptoms, complications, and treatments, including calcium gluconate gel.

Main Results:

  • Dermal symptoms like swelling, redness, blistering, and pain were common (219 cases).

  • Local complications occurred in 3% of cases; no systemic toxicity was observed.
  • Topical calcium gluconate gel was used in 49% of cases, with earlier application correlating to faster symptom resolution.

    • Conclusions:

    • Dermal injury is frequent after exposure to dilute HF consumer products.
    • Adherence to safety guidelines is crucial to prevent HF exposures.
    • Topical calcium gluconate gel appears effective for HF burns, especially when applied promptly.
