Spill & First Aid Emergency Treatment

1. Spill disposal: Evacuate irrelevant personnel, cut all ignition sources; absorb liquid with dry inert sand (no alkaline absorbents); collect waste into airtight steel hazardous waste drum; neutralize residual traces with soda ash dilute solution, prohibit direct sewer discharge
2. Skin contact: Immediately strip all contaminated clothing, flush skin with massive running water continuously ≥30 minutes and rush to hospital for acid burn treatment
3. Eye contact: Irrigate eyes with steady clean running water non-stop for minimum 30 minutes, emergency ophthalmic treatment mandatory
4. Inhalation: Move victim to fresh air instantly, supply pure oxygen for severe cough, dyspnea or pulmonary edema risk
5. Ingestion: Do NOT induce vomiting; drink large volume milk to dilute corrosive acid, carry SDS document for targeted hospital treatment
