General Advice: Remove contaminated clothing quickly, seek medical advice straight away for any discomfort or symptoms.
If Inhaled: Move individual to fresh air, keep at rest in a position comfortable for breathing. If not breathing, provide artificial respiration. Get medical attention if symptoms persist.
In Case of Skin Contact: Wash exposed skin with soap and plenty of water. Remove contaminated clothing and shoes. Seek medical guidance if irritation develops.
If Eye Contact Occurs: Rinse cautiously with water for at least 15 minutes. Lift upper and lower eyelids occasionally. Remove contact lenses if present and easy to do. Continue rinsing and get medical attention.
If Swallowed: Rinse mouth, do not induce vomiting, offer water to drink. Do not give anything by mouth to an unconscious person. Call a poison center or physician immediately.
Most Important Symptoms/Effects: Nausea, headache, dizziness, drowsiness, eye and respiratory irritation, prolonged exposure may affect central nervous system.
Suitable Extinguishing Media: Use water spray, alcohol-resistant foam, dry chemical, or carbon dioxide for firefighting.
Specific Hazards from Combustion: Chlorine, hydrogen chloride, phosgene, and organic vapors may be released during combustion.
Protective Equipment and Precautions for Firefighters: Wear self-contained breathing apparatus (SCBA), full protective gear. Keep containers cool with water spray. Isolate hazardous area and deny entry if safe to do so.
Other Information: Product is combustible under severe fire conditions. Vapors can form explosive mixtures with air. Control runoff to prevent contamination of water sources.
Personal Precautions: Use personal protective equipment, ventilate area, avoid dust, vapor, or mist formation, avoid breathing vapors or spray.
Environmental Precautions: Prevent further leakage or spillage if safe to do so, do not let product enter drains, surface, or groundwater.
Methods for Containment and Cleaning Up: Contain spill and collect with inert absorbent material (sand, earth, vermiculite). Place in a chemical waste container for proper disposal as hazardous waste. Clean contaminated area with water and detergent, ventilate area thoroughly.
Emergency Procedures: Evacuate personnel to safe areas, restrict access, provide adequate ventilation. Follow up with regulatory notifications if contamination occurs.
Precautions for Safe Handling: Avoid contact with skin, eyes, and clothing. Use with adequate ventilation. Do not breathe vapors or dust. Keep away from sources of ignition and incompatible materials. Wear suitable PPE.
Storage Conditions: Store in tightly closed container, away from direct sunlight, strong oxidizers, acids, and heat sources. Keep in cool, dry, well-ventilated area. Protect from physical damage, moisture, and temperature extremes.
Incompatible Materials: Strong acids, strong bases, strong oxidizing agents, reducing agents.
Storage Class: Chemical storage, keep away from food, beverages, and animal feed areas. Maintain proper labeling and inventory controls.
Occupational Exposure Limits: No established workplace limits for this compound, general dust and vapor controls recommended.
Engineering Controls: Use local exhaust ventilation, process enclosures, or other controls to keep airborne levels below recommended exposure limits.
Personal Protective Equipment:
- Eye Protection: Chemical splash goggles or face shield
- Skin Protection: Protective gloves (nitrile rubber, butyl rubber), lab coat or chemical-resistant clothing
- Respiratory Protection: If exposure limits are exceeded or irritation experienced, use appropriate NIOSH/MSHA certified respirator (organic vapor cartridge)
- General Hygiene: Wash hands before breaks and after handling, avoid eating, drinking, or smoking during use
Environmental Exposure Controls: Contain spills, prevent release to sewers or environment, provide spill kits and emergency showers/eyewash in work areas.
