First Aid Measures

Inhalation: Take person to fresh air, ensure breathing is not obstructed, seek medical attention if symptoms persist
Skin Contact: Remove contaminated clothing, wash skin with soap and water, consult doctor if irritation develops
Eye Contact: Rinse with water for minimum 15 minutes, keeping eyelids open, seek immediate medical assistance
Ingestion: Do not induce vomiting, rinse mouth with water, get medical help without delay, provide information on product label or MSDS

Fire-Fighting Measures

Suitable Extinguishing Media: Alcohol-resistant foam, dry chemical powder, carbon dioxide
Fire Hazards: Vapour may travel and ignite at remote locations, emits toxic fumes of oxides of carbon when burning
Protective Equipment: Wear self-contained breathing apparatus and chemical protective suit
Specific Hazards: Closed containers risk explosion if exposed to fire or elevated temperatures

Accidental Release Measures

Personal Precautions: Evacuate unprotected personnel, ventilate area, use personal protective equipment
Environmental Precautions: Prevent spillage into sewers or water sources, contain any runoff
Cleanup Method: Use inert absorbent (sand, vermiculite), collect into containers for disposal according to local regulations
Additional Measures: Isolate area, eliminate any sources of ignition to reduce fire risk

Handling and Storage

Handling: Use in ventilated spaces, avoid contact with eyes and skin, prevent formation of mists, ground all equipment
Storage Conditions: Store in closed, labelled containers away from direct sunlight, extreme temperatures, oxidizing agents
Incompatibilities: Strong acids, alkalis, oxidizers
Safe Storage Temperature: 5–30°C

Exposure Controls and Personal Protection

Exposure Limits: ACGIH TLV 5 mg/m³, OSHA PEL 5 mg/m³
Engineering Controls: Local exhaust ventilation, process enclosure, safety showers and eyewash stations
Personal Protection: Chemical-resistant gloves (nitrile or neoprene), splash goggles, flame-retardant clothing, certified respirator if airborne concentrations risk inhalation
Hygiene Measures: Wash hands and face after working, never eat or smoke during handling, immediately remove contaminated clothing

Toxicological Information

Acute Effects: Inhalation causes nasal and respiratory irritation, high exposures depress the central nervous system
Skin Contact: Prolonged exposure may cause redness, dryness, dermatitis
Eye Contact: Severe irritation, persistent watering
Ingestion: Can result in abdominal pain, vomiting, CNS impairment
Long-Term Effects: Potential reproductive toxicity, animal studies link exposure to developmental impacts
LD50: Oral, rat – 8000 mg/kg

Ecological Information

Environmental Fate: Persistence in soil and water, low rates of biodegradation
Toxicity to Aquatic Life: Highly toxic to fish and invertebrates (EC50 Daphnia magna 2 mg/L)
Bioaccumulation: Potential for bioaccumulation in aquatic organisms
Precautions: Minimize discharge to the environment, observe all applicable disposal regulations

Disposal Considerations

Waste Treatment Methods: Collect and dispose via certified chemical waste facilities, incineration recommended
Container Disposal: Triple rinse containers, puncture, and render unusable before disposal as chemical waste
Avoid: Discharging to surface waters, public sewers
Regulation References: Hazardous Waste Code U069 (US EPA)
