First Aid Measures

Inhalation: Remove person to fresh air, keep at rest, seek medical attention if symptoms develop.
Skin Contact: Remove contaminated clothing, wash skin thoroughly with soap and water, seek medical attention if irritation persists.
Eye Contact: Rinse cautiously with water for several minutes, remove contact lenses if present and easy to do, continue rinsing, seek medical care.
Ingestion: Rinse mouth with water, do not induce vomiting, get medical assistance right away.
Most Important Symptoms: Coughing, shortness of breath, skin or eye irritation, headache, nausea.
Notes to Physician: Treat symptomatically; for severe exposures consider monitoring for methemoglobinemia.

Fire-Fighting Measures

Suitable Extinguishing Media: Dry chemical, foam, carbon dioxide, water spray.
Unsuitable Extinguishing Media: Water jet may scatter powder.
Hazards: Thermal decomposition releases toxic gases such as nitrogen oxides and carbon monoxide.
Protective Equipment: Self-contained breathing apparatus, full protective gear.
Special Procedures: Keep run-off water out of drains and sewers, use water spray for cooling containers.

Accidental Release Measures

Personal Precautions: Avoid dust formation, ventilate area, use appropriate personal protective equipment including gloves and goggles.
Environmental Precautions: Prevent entry into sewers, surface or ground water, contain product with sand or inert material.
Methods for Cleaning Up: Scoop or vacuum up without generating dust, place in labeled containers for disposal, flush area with water if feasible and safe.
Reference to Other Sections: Refer to sections on personal protection and disposal for handling of materials after spillage.

Handling and Storage

Handling: Handle in a chemical fume hood, avoid breathing dust or fumes, keep container tightly closed, ground equipment to prevent static discharge.
Hygiene Practices: Do not eat, drink, or smoke during use, wash hands and any contacted skin before breaks or leaving work area.
Storage: Store in original container, tightly sealed and clearly labeled in a dry, cool, well-ventilated area, isolate from incompatible substances such as oxidizing agents and strong acids.
Recommended Container Materials: Glass or specific chemical-resistant packaging.
Incompatibilities: Strong acids, reducing agents, bases, combustible material.

Exposure Controls and Personal Protection
