## First-Aid Measures
- General Advice: Wear protective equipment, remove contaminated clothing, and move to fresh air. Induce artificial respiration if person is not breathing. Call medical professionals for treatment advice.
- Inhalation: Move affected individual to fresh air and keep calm.
- Skin Contact: Rinse skin with plenty of water for 15-20 minutes.
- Eye Contact: Hold eyes open and rinse with water for 15-20 minutes, removing contact lenses after 5 minutes.
- Ingestion: Do not induce vomiting; give water if person can swallow. Note: No specific antidote.

## Fire-Fighting Measures
- Flash Point: Not applicable (not flammable)
- Extinguishing Media: Foam, dry powder, carbon dioxide, water spray
- Hazards: Carbon monoxide, carbon dioxide, sulfur dioxide, nitrogen oxides, hydrogen chloride, halogenated hydrocarbons, and hydrocarbons may be released during fire.
- Protective Equipment: Firefighters should wear self-contained breathing apparatus.

## Accidental Release Measures
- Personal Precautions: Take protective measures, clear the area, shut off leaks (if safe), extinguish nearby ignition sources, ensure ventilation, and wear suitable clothing.
- Environmental Precautions: Prevent discharge into soil, drains, or groundwater. Contain and clean up spills properly.

## Handling and Storage
- General Advice: Recommendations for manufacturing, commercial blending, and packaging workers only. Follow EPA Worker Protection Standard 40 CFR part 170 for pesticide applicators and workers. Ensure good ventilation, keep container tightly sealed, protect from light, heat, air, and direct contact.
- Protection Against Fire and Explosion: Keep away from ignition sources, extreme heat, oxidizable substances, and electrical equipment (grounded).
