Molecular Formula: C
Inhalation: Move person to fresh air, get medical attention if breathing seems difficult or symptoms persist
Skin Contact: Wash skin thoroughly with soap and water if irritation occurs, remove contaminated clothing
Eye Contact: Rinse eyes cautiously with clean water for several minutes, seek medical advice if discomfort continues
Ingestion: Rinse mouth, drink water if able, seek medical attention if large amount ingested or symptoms develop
Symptoms/Effects: Mechanical irritation, coughing, short-lived respiratory discomfort or eye redness
Extinguishing Media: Water spray, foam, dry chemical, carbon dioxide
Specific Hazards: Dust may present explosion risk if dispersed in air and exposed to ignition source; combustion produces CO, CO2, potentially irritating fumes
Protective Equipment: Firefighters should wear self-contained breathing apparatus and full protective clothing
Advice for Firefighters: Avoid inhaling combustion products; move containers away from fire if safe
Personal Precautions: Wear respiratory protection, gloves, goggles; avoid generating dust and inhaling particles
Environmental Precautions: Prevent further leakage or spillage if safe; do not let product enter drains or waterways
Cleanup Methods: Use shovel or vacuum equipped with HEPA filter to collect; avoid dry sweeping; place in suitable closed containers for disposal
Reference to Other Sections: See Section 8 for personal protection and Section 13 for waste disposal
Handling: Work in well-ventilated areas; avoid breathing dust and creating airborne concentrations; wash hands before breaks and after handling
Storage: Store in dry, cool, well-ventilated conditions; keep containers tightly closed; avoid storing near strong oxidizers or moisture sources
Incompatible Materials: Strong oxidizing agents, acids, sources of ignition
Hygiene Practices: Keep away from food, drink, and animal feed; avoid contact with skin, eyes, and clothing
Occupational Exposure Limits: ACGIH TLV (respirable): 2 mg/m3 (graphite, natural), OSHA PEL: 5 mg/m3 (respirable fraction), 15 mg/m3 (total dust)
Engineering Controls: Adequate local exhaust ventilation required for dust control; maintain low airborne concentrations
Personal Protective Equipment: Respiratory protection (N95 mask or better), protective gloves, chemical safety goggles, long-sleeved clothing
Environmental Controls: Prevent dust accumulation and emission to air or water
Other Protective Measures: Safety shower and eyewash station near work area

Chemical Stability: Stable under normal conditions
Possibility of Hazardous Reactions: No dangerous reaction known under normal use
Conditions to Avoid: Exposure to strong oxidizers, excessive heat, open flames, sources of ignition, generating dust clouds
Incompatible Materials: Avoid storing with strong acids (sulfuric, nitric), oxidizing agents (peroxides, chlorates)
Hazardous Decomposition Products: Carbon monoxide, carbon dioxide, minor amounts of sulfur or other decomposition byproducts depending on expansion agents
Acute Toxicity: Inhalation of dust can cause mild respiratory discomfort; considered practically non-toxic by oral, dermal, or inhalation exposure
Skin Corrosion/Irritation: Prolonged contact with dust may produce mild irritation; not a sensitizer
Serious Eye Damage/Irritation: Mechanical irritation (redness, itching, tearing)
Respiratory or Skin Sensitization: Not sensitizing based on available data
Germ Cell Mutagenicity: No data indicating mutagenic effects
Carcinogenicity: Not classified as carcinogenic by IARC, NTP, ACGIH, or OSHA
Reproductive Toxicity: No information suggests reproductive hazard
Specific Target Organ Toxicity (Single Exposure): Possible temporary irritation of respiratory tract (from dust)
Specific Target Organ Toxicity (Repeated Exposure): Data does not support chronic toxicity from standard workplace exposures
Aspiration Hazard: Not expected to be an aspiration hazard
Toxicity: Product poses minimal risk to aquatic and terrestrial environments in bulk or dispersed form
Persistence and Degradability: Chemically inert, not readily biodegradable, remains in environment unless physically removed
Bioaccumulative Potential: Not bioaccumulative due to insolubility and lack of significant mobility in biological systems
Mobility in Soil: Remains at surface or in sediment; does not migrate readily
Other Adverse Effects: No evidence of significant effects on wildlife or ecosystems at currently known release levels
Waste Treatment Methods: Collect in closed, labeled containers; dispose of through facility’s chemical waste process or at approved industrial landfill
