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.

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