Environmental hazards

REGULATORY STATUS

Principle Routes of Exposure

In dust form, inhalation is the primary route of exposure.

Potential health effects

Eyes: In dust form, may be abrasive and irritating to the eyes. Skin: In dust form, may cause mild irritation. If exposure limits are exceeded, the respiratory tract Inhalation: may become irritated. May cause shortness of breath, coughing and/or chest tightness due to temporary physical overloading of the lungs. Ingestion: May cause gastrointestinal disturbances.

Medical Conditions Generally Aggravated by Exposure

Persons with pre-existing respiratory impairments including, emphysema and asthma. EXPOSURE

Potential chronic health

Eyes: In dust form, may be abrasive and irritating to the eyes through mechanical abrasion. Skin: In dust form, may be abrasive and irritating to the skin through mechanical abrasion. Prolonged or repeated inhalation of dust may cause Inhalation: pulmonary fibrosis or emphysema. Possible lung cancer hazard. Ingestion: May cause nausea, vomiting, and diarrhea. FIRST AID MEASURES – SECTION 4 SEEK MEDICAL ATTENTION FOR ALL CASES OF OVEREXPOSURE. FIRST AID MEASURES: Flush thoroughly with water, taking special care to rinse under the eyelids. Do not rub the eye as mechanical abrasion due to the dust Eyes: may be damaging to the cornea. If irritation persists, continue flushing for fifteen (15) minutes. If discomfort persists, seek consultation from a physician. Remove contaminated clothing. Wash irritated area thoroughly with Skin: water. Do not rub as mechanical abrasion due to the dust may prolong irritation to the skin. Inhalation: If overcome by dust concentrations, remove to a more ventilated area (fresh air). Ingestion: Do not induce vomiting. Seek consultation from a physician. Instructions None recommended. for Physician: FIRE FIGHTING MEASURES – SECTION 5

Extinguishing Media: Use any means suitable for extinguishing surrounding fire. Prohibited Extinguishing Media: Avoid high-pressure water stream as this may spread burning powder (burning powder will float). Firefighting Instructions: In the event of a fire, wear full protective clothing and NIOSH-approved self-contained breathing apparatus with full face-piece operated in the pressure demand or other positive pressure mode. Unusual Fire and Explosion Hazards: In dust form, this material is combustible at high temperatures. Dusts may form explosive mixtures in air. Material itself burns with difficulty. ACCIDENTAL RELEASE MEASURES – SECTION 6 Environmental Precautions: Spill and releases of this material to navigable water in sufficient amounts that cause sludge or emulsion under the water must be reported immediately to the National

Response

Center (800/424-8802), as required by U.S. Federal Law. Contact the Coast Guard and appropriate state and local regulatory agencies. Failure to report these spills may result in substantial civil and criminal penalties. Cleanup Methods: Small spills: should be vacuumed when possible. Dry sweeping is not recommended. A vacuum equipped with HEPA (high efficiency particulate air) filtration is recommended. If necessary, light water spray will reduce dust for dry sweeping. Large spills: may be shoveled into containers. Wear appropriate personal protective equipment and respiratory protection. HANDLING & STORAGE – SECTION 7 Avoid handling that will unnecessarily generate airborne dust. Handling: Graphite is a good conductor of electricity. Exercise caution when handling in areas where contact with electrical circuitry is possible. Keep in a tightly closed container, stored in a cool, dry, ventilated area. Protect against physical damage. Containers

Storage

of this material may be hazardous when empty since they retain product residues (dust, solids); observe all warnings and precautions listed for the product. Specific Uses: Users should avoid inhalation of dust. EXPOSURE CONTROLS / PERSONAL PROTECTION – SECTION 8 EXPOSURE CONTROLS: Exposure Limit Values

Conditions to Avoid: Incompatibilities with strong oxidizers. This condition is aggravated when the material is heated. Materials to Avoid: Graphite reacts vigorously with liquid potassium, potassium peroxide and will ignite with chlorine trifluoride and fluorine. If graphite contacts liquid potassium, rubidium, or caesium at 300C, intercalation compounds may be formed. These compounds may explode on contact with water or ignite in air. Hazardous Decomposition Products: Carbon monoxide, carbon dioxide. Hazardous Polymerization: Polymerization will not occur with this material. TOXICOLOGICAL INFORMATION – SECTION 11 Type of Test Route of Effects Species Dose Data Exposure Observed No Information Available ECOLOGICAL INFORMATION – SECTION 12 Ecotoxicity: No effects are expected from this material due its insolubility. Insolubility leads to non- bioavailability.
