TYPES OF HAZARD/ EXPOSURE ACUTE HAZARDS/ SYMPTOMS PREVENTION FIRST AID/
FIRE FIGHTING
FIRE Highly flammable or combustible depending on physical form.
NO open flames, NO sparks, and NO smoking.
Powder, water spray, foam, carbon dioxide.
EXPLOSION Finely dispersed particles form explosive mixtures in air.
Prevent deposition of dust; closed system, dust explosion-proof electrical equipment and lighting. 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
Safety goggles.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
 •INGESTION


SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
Sweep spilled substance into covered containers; if appropriate, moisten first to prevent dusting. Remove to safe place. (Extra personal protection: P1 filter respirator for inert particles).
Fireproof. Separated from strong oxidants.
Airtight.
UN Hazard Class: 4.2

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

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.
MAK not established.
OSHA PEL: TWA 15 mg/m3 (total) TWA 5 mg/m3 (resp)
NIOSH REL: See Appendix D
NIOSH IDLH: N.D. See: IDLH INDEX


ROUTES OF EXPOSURE:


INHALATION RISK:
Evaporation at 20C 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
Boiling point: >4000C
Melting point: >3500C
Relative density (water = 1): 1.8-3.51
Solubility in water:

DATA

N O T E S
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).
