TYPES OF
HAZARD / EXPOSURE |
ACUTE HAZARDS / SYMPTOMS | PREVENTION | FIRST AID / FIRE FIGHTING |
| FIRE |
Combustible under specific conditions.
|
NO open flames.
|
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.
|
In case of fire: keep drums, etc., cool by spraying with water.
|

| EXPOSURE |
|
PREVENT DISPERSION OF DUST!
|
|
| Inhalation |
Cough.
|
Ventilation, local exhaust, or breathing protection.
|
Fresh air, rest.
|
| Skin |
Roughness.
|
Protective gloves.
|
Rinse and then wash skin with water and soap.
|
| Eyes |
|
Safety spectacles, or eye protection in combination with breathing protection if powder.
|
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
|
| Ingestion |
|
|
Rinse mouth. Rest.
|
| SPILLAGE DISPOSAL | PACKAGING & LABELLING |
Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting. Then wash away with plenty of water. Wash away remainder with plenty of water (extra personal protection: P1 filter respirator for inert particles).
|
|
| EMERGENCY RESPONSE | STORAGE |
|
Separated from strong oxidants. Dry. Keep in a well-ventilated room.
|
| IMPORTANT DATA | |
|
PHYSICAL STATE; APPEARANCE:
BLACK FLAKES, LUMPS, POWDER , CHIPS. PHYSICAL DANGERS: Dust explosion possible if in powder or granular form, mixed with air. CHEMICAL DANGERS: The substance is a strong reducing agent and reacts with oxidants. OCCUPATIONAL EXPOSURE LIMITS: TLV: ppm; 2.0 mg/m 3 as respirable dust (ACGIH 1996-1997). |
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation. INHALATION RISK: Evaporation at 20°C is negligible; a nuisance-causing concentration of airborne particles can, however, be reached quickly. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: Lungs may be affected by repeated or prolonged exposure to dusts , resulting in graphite pneumoconiosis. |
| PHYSICAL PROPERTIES | |
|
Sublimation point: 3652°C
Relative density (water = 1): 2.09-2.23 Solubility in water: insoluble |

| NOTES | |
|
See Synthetic graphite CAS 7440-44-0. Synthetic and natural graphite may be mixed and many graphite products contain deliberate additives such as cristobalite, clay, coal, and petroleum products. Natural Graphite is usually found associated with impurities such as mica, iron oxide, granite and free silica. Content can range 2-25%.
