TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Highly flammable if powdered. Combustible.  NO open flames, NO sparks and NO smoking.  Use water spray, powder, foam, carbon dioxide. 
EXPLOSION Finely dispersed particles form explosive mixtures in air.  Closed system, ventilation, explosion-proof electrical equipment and lighting. Prevent deposition of dust. Prevent build-up of electrostatic charges (e.g., by grounding).  In case of fire: keep drums, etc., cool by spraying with water. 
 
EXPOSURE      
Inhalation      
Skin      
Eyes   Wear safety goggles.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion      

SPILLAGE DISPOSAL
PACKAGING & LABELLING
Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting. Store and dispose of according to local regulations. Personal protection: particulate filter respirator adapted to the airborne concentration of the substance.  Airtight. 
EC Classification
 
UN Classification
UN Hazard Class: 4.2 
GHS Classification
 

EMERGENCY RESPONSE SAFE STORAGE
  Fireproof. Separated from strong oxidants. 

IMPORTANT DATA
Physical State; Appearance
BLACK POWDER OR SOLID IN VARIOUS FORMS. 

Physical dangers
Dust explosion possible if in powder or granular form, mixed with air. If dry, it can be charged electrostatically by swirling, pneumatic transport, pouring, etc. 

Chemical dangers
The substance may ignite spontaneously on contact with air. On combustion, forms toxic carbon monoxide if ventilation is insufficient. The substance is a strong reducing agent. It reacts violently with oxidants such as bromates; chlorates and nitrates. 

Occupational exposure limits
TLV (NOT-ESTABLISHED):. 

Routes of exposure
 

Inhalation risk
Evaporation at 20°C is negligible; a nuisance-causing concentration of airborne particles can, however, be reached quickly. 

Effects of short-term exposure
 

Effects of long-term or repeated exposure
 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Boiling point: >4000°C
Melting point: >3500°C
Relative density (water = 1): 1.8-3.51
Solubility in water: none 
 

NOTES
Health effects of exposure to the substance have been investigated, but none has been found.
This card applies to pure carbon in a non-fibrous form.
Carbon fibres or carbon containing polycyclic aromatic hydrocarbons may pose different hazards.
Also consult ICSC # 0471 carbon black and ICSC # 0893 graphite (natural).
