Impurities: None contributing to classification
Inhalation: Remove affected person to fresh air immediately. Provide oxygen if breathing is difficult, call for medical assistance without delay.
Skin Contact: Take off contaminated clothing, wash skin well with plenty of running water for at least 15 minutes, seek medical help because burns may develop.
Eye Contact: Rinse cautiously with water for at least 20 minutes keeping eyelids open, urgent immediate medical attention is necessary.
Ingestion: Rinse mouth without inducing vomiting, do not give anything by mouth if unconscious, call poison control and seek hospital care.
Advice to Physician: Treat as corrosive chemical exposure, monitor for respiratory distress, consider endoscopy for ingestion injuries
Suitable Extinguishing Media: Use alcohol-resistant foam, dry chemical powder, or carbon dioxide
Unsuitable Extinguishing Media: Water jets may spread burning liquid
Specific Hazards: Vapors form explosive mixtures with air, toxic gases (carbon monoxide and carbon dioxide) evolve in fires
Firefighter Protection: Wear full protective clothing and self-contained breathing apparatus
Special Procedures: Move containers from fire area if safe, keep cool by spraying with water from safest distance
Personal Precautions: Keep unnecessary personnel away, avoid contact with spilled product, use splash-proof goggles, acid-resistant gloves, and respirator if needed
Environmental Precautions: Do not allow to enter sewers, waterways, or soil; contain runoff using sand or inert materials
Clean-Up Methods: Ventilate area, absorb liquid with sand or vermiculite, transfer to closed container for disposal, neutralize residue with sodium bicarbonate solution
Decontamination: Wash area with water after removing majority of material
Handling: Always handle in a chemical fume hood or well-ventilated area, avoid generating vapor or mist, use only non-sparking tools, ground and bond containers when transferring
Storage: Store in tightly closed, corrosion-resistant containers, keep in cool, well-ventilated place away from sunlight, heat, ignition sources, oxidizers, and strong bases
Packaging Materials: Use glass, stainless steel, or specific high-density plastics approved for acid storage
Special Notes: Keep away from incompatible materials, signs and MSDS should stay near storage
Exposure Limits: OSHA PEL: 10 ppm (25 mg/m³); ACGIH TLV: 10 ppm, STEL: 15 ppm (37 mg/m³)
Engineering Controls: Use local exhaust ventilation, safety showers, and eyewash stations
Personal Protective Equipment: Chemical splash goggles, acid-resistant gloves, apron, and full-face shield for bulk handling
Respiratory Protection: Approved respirators required if vapor concentrations exceed limits or during emergency response
Hygiene Measures: Wash hands, forearms, and face thoroughly after handling, remove contaminated clothing immediately
Environmental Controls: Prevent release to environment using containment, monitor for spills and leaks regularly
