Signal Word: Danger

Composition / Information on Ingredients

Component: 2,3-Dichloronitrobenzene
Purity: Typically above 97% in industrial applications
Additives: None commonly present
Impurities: Trace compounds may exist, usually less than 1%

First Aid Measures

Inhalation: Remove individual to fresh air, loosen clothing, watch for signs of distress, seek medical attention for continued symptoms
Eye Contact: Rinse eyes gently with plenty of water for at least 15 minutes, lift eyelids regularly, call a physician if irritation persists
Skin Contact: Wash thoroughly with soap and water, remove contaminated clothing, consult a doctor if irritation remains
Ingestion: Rinse mouth, do not induce vomiting, drink water if the person is conscious, seek immediate medical help

Fire-Fighting Measures

Suitable Extinguishing Media: Dry chemical, CO2, foam, or water spray
Hazards During Fire: Heating can release gases like hydrogen chloride, nitrogen oxides, and phosgene
Protective Equipment: Firefighters wear self-contained breathing apparatus, full protective gear to guard against toxic vapors
Firefighting Tactics: Avoid letting firewater seep into drains, stay upwind, isolate the hazard zone if possible

Accidental Release Measures

Personal Precautions: Wear chemical-resistant gloves, goggles, and appropriate respirator
Environmental Precautions: Block off area, prevent spillage from reaching water sources or sewers
Containment: Use inert absorbents like sand or vermiculite for collection
Cleanup Methods: Scoop up carefully, store in labeled waste containers, ventilate area well, dispose safely

Handling and Storage

Safe Handling: Work under fume hood, avoid contact with skin and eyes, avoid breathing dust or vapor
Storage Tips: Keep containers tightly closed, store in a well-ventilated, cool dry area, separate from solvents, oxidizers, and acids
Shelf Life: Stable for long periods if kept in sealed containers, away from direct sunlight and moisture

Exposure Controls and Personal Protection

Occupational Exposure Limit: No established OSHA or ACGIH limit for this specific chemical, minimize exposure by best practice
Engineering Controls: Use local exhaust ventilation, maintain negative pressure in storage areas
Protective Equipment: Respirator if airborne concentrations are high, chemical goggles, nitrile gloves, lab coat
Hygiene Measures: Wash hands and face thoroughly after handling, remove contaminated clothing before leaving work area
