Product or Trade Name.... Graphite (Sometimes incorrectly called "carbon")
Emergency Overview:
Contains no ingredients now known to be hazardous by OSHA.
The normal sharpening of the rod, whether being done in a carbon rod sharpener
or honeing with a razor blade,
is suspected of generating small amounts of possibly respirable fibers.
We believe that such sharpening should be done in a ventilated hood facility.

No hazardous components as defined by OSHA.
313 Listed Chemicals
If none are listed here, there are no 313 chemicals present above
threshold values.
NFPA (Scale 0-4):
Not known
Potential Health Effects:
Eye: Dust may cause eye irritation
Skin Contact: Dust may cause skin irritation.
Skin Absorption: Not expected to be a major route of entry.
Ingestion: Not known
Inhalation: Small graphite fibers or dust are suspected as being possible
inhalation hazards. However, in this product, fibers have never
been detected, only dust particles.
Chronic effects: A review of the literature does not show obvious long
term hazard.
Carcinogenicty: No component known to be present in this product and is
at > 0.1% is presently listed as a carcinogen by IARC
or OSHA unless other wise noted.
Routes of exposure: Inhalation
Permissible exposure:
15 MCCPF OSHA TWA, 10 mg/m3 ACGIH TWA (Total Dust)
CIRCLA Hazard Ratings:
Toxicity: 1 Ingnitgability: 0 Reactivity: 0 Persistence: 3
Toxicological Information:
Graphite causes benign pneumoconiosis (graphitosis). Symptoms of
pneumoconiosis from graphite exposure are dypsnea, coughing, black sputum,
bronchitis, ventricular hypertropy and impairment of pulmonary function.
X-rays will show progressive nodulation of the lungs. The theshold limit
value was set in conformity with the limit for free crystalline silica,
which may be present in graphite.
Incompatibilies:
Strong oxidizers,fluorine, peroxides
Route of entry: Inhalation, Skin or eye contact.
Target organs: Lungs, Cardiovascular system.
Symptoms:
Coughing, forceful expiration. Dyspnea, difficulty in breathing.
Black sputum, black colored expectorate. Bronchitis, inflamed bronchial
mucous membranes, pulmonary fibrosis, fibrous tissue involving lungs.
Pneumoconiosis, degenerative respiratory disease.
Eyes: In case of contact, immediately flush eyes with copious amounts of
flowing water for at least 15 minutes, retracting eye lids often.
Get medical attention immediately. Contact lenses should not be
worn when working with this product.
Skin: Wash skin thoroughly with mild soap and water. Flush with luke warm
water for 15 minutes.
Inhalation: If large amounts of the dust are inhaled, move the exposed
person to fresh air at once. If symptoms persist contact
physician.
Ingestion: Not known
Flammability classification: Not classified.
Flash Point/Method: Not known, but very high!
Auto-Ignition Temperature: Not determined
Flammable Limits: Lower: Not applicable
Upper: Not applicable
Extinguishing Media: Non-burning
Special Conditions to Avoid: None known
Hazardous products of Combustion: None known
Unusual Fire Hazards: None known
Firefighting procedures/instructions:
Treat the surrounding fire; this product is non-burning.
Properties that could increase fire or explosion hazard:
None known.
This product is not subject to "accidental release" in the form of normal use.
Storage and handling: Store in the containers in which the product is shipped, tightly sealed.
Personal Protective Equipment (PPE): Eye/Face Protection: ANSI 87.1 approved safety glasses with side shield when sharpening these rods, either with razor blade or carbon rod sharpener or plain wood file. Skin Protection: No particular protection needed when handling this material on an occasional basis. Respiratory Protection: For the occasional breaking of a rod, which might require "scoring" the surface to get a clean break, protection is not needed. But if some large number of rods was going to be broken in this way then such an operation should be done in a chemical fume hood with exhaust. Other: None known
Appearance: Black rods, with possibly "greasy" feel Color: Black pH: Not applicable Odor: None Vapor Pressure: Not applicable Vapor Density (Air=1): Not available Boiling Point/Range: >3000° C Melting Point/Range: Not available Specific Gravity: 2 to 2.5 g/cc Solubility in water: None Softening Point: Not determined Molecular Formula: Not known Molecular Weight: 12.01 %Volatile by Volume: Not determined Evaporation Rate (n-butyl acetate = 1): Not available Viscosity: Not available Bulk Density: Not determined
Chemical Stability: The product is stable under normal use conditions. Reactivity: This material is not reactive. Conditions to Avoid: Heat, sparks, flames, and other ignition sources; avoid heating above 290° C (554° F) Incompatibility (materials to avoid): Strong oxidizers, fluorine, peroxides Hazardous Products of Decomposition: None known Reactions with Air and Water: None known
Eye Effects: Dust from this material may cause eye irritation. Skin Effects, Contact: Concentrate may cause skin irritation Skin Effects, Absorption: No absorption or acute effects expected. However the dust might cause some mild irritation of the skin. Acute Oral Effects (Ingestion): None known Acute Inhalation Effects: None known. Chronic Effects: A review of the literature does not show obvious long term hazard. Carcinogenicity: No component known to be present in this product at > 0.1% is presently listed as a carcinogen by IARC, NTP, or OSHA unless otherwise noted in Section 16.
Exotoxicity: No ecological information is available for this product.
US EPA Hazardous Waste Numbers:
This product as purchased does not fall under current US EPA
(Environmental Protection Agency) RCRA definitions of hazardous
waste. Under RCRA it is the generator's responsibility to determine
the status of the waste at the time of its disposal.
General Disposal Considerations:
