What is the general approach to exposure to hydrofluoric acid in the field?

• A. Immediate decontamination with copious water rinse; do not neutralize; seek specialized care promptly; protect responders from secondary exposure
• B. Neutralize with baking soda before rinsing
• C. Evacuate before any decontamination
• D. Brush off dry chemicals and continue with transport

Answer: (A)

The main idea is that exposure to hydrofluoric acid in the field must be addressed with rapid, thorough water decontamination and prompt specialist care, while protecting responders from secondary exposure. Hydrofluoric acid is especially dangerous because fluoride ions can deeply penetrate skin and tissues and cause serious local burns plus potential systemic effects, including hypocalcemia. Therefore the priority is to flush the affected area with copious amounts of clean water as quickly as possible to wash away the chemical and limit absorption. Do not try to neutralize the chemical in the field; using baking soda or other neutralizers can generate heat, may worsen tissue penetration, or create additional exposure, and it delays effective irrigation. After flushing, remove contaminated clothing and seek specialized medical care promptly, since advanced treatment (and calcium-based interventions) may be needed for systemic toxicity. Protect responders from secondary exposure by maintaining proper PPE and decontamination procedures. Evacuating before decontamination and brushing off dry residues before decontamination can spread the contamination or delay proper decontamination, so they aren’t appropriate in this scenario.
