Eye Contact: Immediately rinse with copious amounts of water for at least 15 minutes, remove contact lenses if applicable, seek medical advice without delay
Skin Contact: Remove contaminated clothing, wash affected area thoroughly with soap and water, get medical attention if symptoms develop
Inhalation: Move to fresh air immediately, ensure unobstructed breathing, administer oxygen if breathing is difficult, seek medical attention
Ingestion: Rinse mouth, do not induce vomiting, give water to drink if conscious, call physician or poison center promptly
Important Symptoms: Nausea, headache, skin irritation, shortness of breath, dizziness, abdominal pain
Advice to Physician: Treat symptomatically, consider effects on liver and kidneys, monitor for metabolic acidosis
Suitable Extinguishing Media: Dry chemical powder, carbon dioxide, foam, water spray (do not use water jet)
Unsuitable Extinguishing Media: Avoid straight water streams
Specific Hazards: Decomposition emits toxic fumes (nitrogen oxides, carbon oxides)
Protective Equipment: Firefighters must wear self-contained breathing apparatus and protective clothing
Special Precautions: Cool containers with water spray, avoid inhalation of combustion products, evacuate area if necessary, move containers away from fire if possible
Personal Precautions: Avoid contact with skin, eyes, and clothing, ensure adequate ventilation, wear suitable personal protective equipment (PPE), remove ignition sources
Environmental Precautions: Prevent infiltration into sewers, groundwater, or waterways
Methods for Containment: Collect spilled material with non-combustible, absorbent material, place in clearly labeled, sealed containers for disposal
Cleanup Procedures: Ventilate area, decontaminate tools and surfaces, dispose of waste according to local, state, and federal regulations
Handling: Use only in well-ventilated areas, avoid dust formation, do not breathe dust or vapor, keep away from heat, sparks, open flames, ensure containers remain tightly closed
Hygiene Practices: Wash hands after handling, do not eat, drink or smoke in work area, change contaminated clothing
Storage: Store in a cool, dry, well-ventilated area, away from incompatible substances such as strong acids, bases, reducing and oxidizing agents, keep container tightly sealed, prevent moisture ingress
Incompatibilities: Strong acids, strong bases, strong oxidizing agents, reducing agents
Engineering Controls: Use chemical fume hood or local exhaust ventilation, keep airborne concentrations below established limits
Exposure Limits: No specific occupational exposure limits set, control airborne exposure as low as reasonably achievable
Eye Protection: Chemical safety goggles, face shield
Skin Protection: Chemical-resistant gloves (nitrile, butyl rubber), lab coat, impermeable clothing
Respiratory Protection: Dust mask or respirator (NIOSH-approved) if exposure limits might be exceeded
Other Protective Equipment: Emergency eyewash and safety shower in immediate work area, avoid static discharge buildup
