TYPES OF HAZARD / EXPOSURE	ACUTE HAZARDS / SYMPTOMS	PREVENTION	FIRST AID / FIRE FIGHTING
FIRE	Combustible.	NO open flames. NO contact with hot surfaces.	Use 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! AVOID ALL CONTACT!
Inhalation	Cough.	Use closed system.	Fresh air, rest.
Skin		Protective gloves.	Rinse and then wash skin with water and soap.
Eyes	Redness.	Wear safety goggles or eye protection in combination with breathing protection.	Rinse with plenty of water (remove contact lenses if easily possible).
Ingestion		Do not eat, drink, or smoke during work. Wash hands before eating.	Rinse mouth.

SPILLAGE DISPOSAL	PACKAGING & LABELLING
Personal protection: complete protective clothing including self-contained breathing apparatus. Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations.	EC Classification UN Classification GHS Classification Signal: Warning Suspected of causing cancer if inhaled May cause damage to lungs through prolonged or repeated exposure if inhaled

EMERGENCY RESPONSE	SAFE STORAGE
	Well closed. Separated from food and feedstuffs. See Chemical Dangers.

IMPORTANT DATA

Physical State; Appearance
ODOURLESS BLACK PELLETS OR EXTREMELY FINE POWDER.

Physical dangers
Dust clouds can be ignited on contact with intensely heated surfaces (above 500°C).

Chemical dangers
The substance is a strong reducing agent. It reacts violently with oxidants and many other substances.

Occupational exposure limits
TLV: 3.5mg/m³ as TWA; A4 (not classifiable as a human carcinogen); (ACGIH 2010).
MAK: Carcinogen category: 3B; (DFG 2009).

Routes of exposure
The substance can be absorbed into the body by inhalation.

Inhalation risk
A harmful concentration of airborne particles can be reached quickly when dispersed.

Effects of short-term exposure
May cause mechanical irritation.

Effects of long-term or repeated exposure
Lungs may be affected by repeated or prolongated exposure. This substance is possibly carcinogenic to humans.

PHYSICAL PROPERTIES	ENVIRONMENTAL DATA
Melting point: ca. 3550°C Relative density (water = 1): 1.8-2.1 Solubility in water: none Auto-ignition temperature: above 500°C

NOTES

Uses of this substance as ultra-fine particles (<100nm) (nanoparticles) may produce adverse effects at concentrations well below those indicated on this Card. Utmost care should be taken.
Polyaromatic hydrocarbons (PAH) are reportedly present in some carbon blacks.
Depending on the process of manufacture, there are variations in their chemical compositions.
Carbon blacks containing over 8% volatiles may pose an explosion hazard (see Physical Dangers).
Most carbon black powders will not have a UN number, however, depending on the specification of the powder, possible UN numbers are: 1361, class 4.2, packing group I or II; or UN 1362, class 4.2, packing group III.
The GHS classification will also vary according to the specification of the powder.
