Natural Flake Graphite Material Safety Data Sheet (MSDS)

NB: We are not a graphite manufacturer, nor subject to any regulations or directives to publish a MSDS. The following has been created solely for educational purposes for our site visitors.

Section 1 - Chemical Product Identification

Product Name: Natural Flake Graphite - various grades in particle size and purity
Synonyms: Black lead, crystallized carbon, plumbago, mineral carbon, C.I. 77265
Chemical Family: Carbon
Chemical Name: Graphite
Formula: C

Section 2 - Hazards Identification


HMIS Hazard Rating     NFPA Hazard Rating

Graphite is not a hazardous or toxic material. However, it may contain trace amounts of silica.
HMIS Hazard Rating: Health - 1, Flammability - 0, Physical Hazards - 0
Appearance: Fine steel grey to black odorless flakes with metallic lustre
Primary Route(s) of Entry: Inhalation into lungs
Potential Health Effects
Eye Contact: May cause mild irritation and reddening.
Skin Contact: May cause mild irritation and redness. No evidence of long term health effects.
Ingestion: Ingestion of large amounts may cause gastrointestinal irritation.
Inhalation: May irritate respiratory tract. Symptoms may include coughing, shortness of breath and black sputum. Chronic exposure to graphite is associated with the development of pneumoconiosis, a disease of the lungs. Trace amounts of silica may lead to lung disease, silicosis or cancer.

Section 3 - Composition, Information on Ingredients

CAS# Chemical Name & Formula Percent EINECS/ELINCS
7782-42-5 Graphite (C) 94-99 231-955-3
14808-60-7 Silica (SiO2) < 3 238-878-4

Section 4 - First Aid Measures

Eyes: Immediately flush eyes adequately with water, occasionally lifting the upper and lower eyelids. Get medical attention if irritation persists.
Skin: Immediately flush skin with soap and plenty of water. Remove contaminated clothing and shoes. Wash clothing and clean shoes before reusing. Get medical aid if irritation develops or persists.
Ingestion: Graphite flake is typically inert but and little information is available. However, if victim has swallowed a large amount and is conscious and alert, rinse mouth thoroughly with water followed by more water to drink. Never give anything by mouth to an unconscious person. Get medical aid immediately.
Inhalation: Remove from exposure and move to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical attention. Chronic exposure to graphite is associated with the development of pneumoconiosis, a disease of the lungs. Even though crystalline silica may be present in very small amounts, prolonged inhalation exposure may produce silicosis and other lung diseases including lung cancer.

Section 5 - Fire Fighting Measures

Graphite flake does not burn or support combustion under normal conditions. However, if the flake is ground to very fine micron and sub-micron size, it can ignite spontaneously in the presence of oxygen.
Flash Point: N/A
Flammability: N/A
Explosion: Not considered to be an explosion hazard.
Extinguishing Media: Spray water, or any means suitable to extinguish surrounding fire.
Special Information: 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 as graphite, when heated, can react with oxygen to produce CO and CO2.

Section 6 - Accidental Release Measures

Ventilate area of leak or spill. Wear protective equipment to avoid eye irritation and contact with skin. Sweep and/or shovel avoiding or minimizing dust generation and containerize for reclamation or disposal. If vacuum equipment is used, ensure it is properly grounded to avoid static charges.

Section 7 - Handling and Storage

Handling: Avoid contact with eyes, skin and clothing by wearing appropriate gear. Do not breathe dust. If dust is generated, wear appropriate protection as described in Section 8.
Storage: Keep in a cool ventilated area in a tightly closed container keeping the product dry. Avoid contact with strong oxidizing agents. Protect container against physical damage and dispose of safely when emptied due to possible contained dust.

Section 8 - Exposure Controls/Personal Protection

Engineering Controls: Facilities storing or utilizing this material should be equipped with eyewash stations and emergency showers. Use adequate ventilation equipment to keep airborne particulate within acceptable exposure limits.
Personal Protection: Safety glasses or goggles should be worn. Wear appropriate protective gloves, clothing and shoes to minimize contact with the skin. Ambient airborne concentrations should be monitored and if the recommended exposure limit is exceeded, wear a NIOSH/MSHA approved dust respirator.
Exposure Limits: This product should be treated as a nuisance dust.
Graphite: CAS# 7782-42-5 EC# 231-955-3
ACGIH: TWA 2mg/m³ (respirable fraction)
NIOSH REL: TWA 2.5mg/m³
OSHA PEL: TWA 15ml/m³
Silica: CAS# 14808-60-7 EC# 238-878-4
ACGIH: TWA 0.025mg/m³ (respirable fraction)
NIOSH REL: TWA 0.05 mg/m³
OSHA PEL: TWA 30mg/m³ (%SiO2+2), total dust
TWA 10mg/m³ (%SiO2+2), respirable fraction
Where %SiO2 is the percentage of crystalline silica determined by airborne samples as defined by 29 CFR 1910.1000, Z-3.

Section 10 - Stability and Reactivity

Chemical Stability: Graphite and silica are stable and relatively inert under normal conditions of use and storage.
Reactivity: Graphite will react with oxygen at higher temperatures to produce carbon monoxide and/or carbon dioxide. The finer the flake, the more reactive it will be due to larger surface area. Graphite reacts vigorously with liquid potassium, potassium peroxide and will ignite with chlorine trifluoride and fluorine. If graphite contacts liquid potassium, sodium, rubidium or caesium at 300°C, intercalation compounds may be formed. These compounds ignite in air and may react explosively with water.
Hazardous Polymerization: None.
Hazardous Decomposition Products: None. Graphite, being a form of elemental carbon, cannot break down but can produce hazardous products with other elements and compounds as indicated above.Incompatibilities: Strong oxidizing agents, fluorine, halogenated solvents, potassium and potassium oxides.
