TYPES OF HAZARD/ EXPOSURE	ACUTE HAZARDS/ SYMPTOMS	PREVENTION	FIRST AID/ FIRE FIGHTING
FIRE	Combustible.	NO open flames. NO contact with hot surfaces.	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.	Closed system.	Fresh air, rest.
•SKIN		Protective gloves.	Rinse and then wash skin with water and soap.
•EYES	Redness.	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

STORAGE

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 remove to safe place.

Well closed. Separated from food and feedstuffs . See Chemical Dangers.

Signal: Warning
Health haz
Suspected of causing cancer if inhaled
May cause damage to lungs through prolonged or repeated exposure if inhaled

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 and reacts violently with oxidants. Reacts violently with many compounds.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 3.5 mg/m³ as TWA A4 (not classifiable as a human carcinogen); (ACGIH 2010).
MAK:
Carcinogen category: 3B
(DFG 2009).
OSHA PEL: TWA 3.5 mg/m³
NIOSH REL: TWA 3.5 mg/m³ Ca TWA 0.1 mg PAHs/m³ Carbon black in presence of polycyclic aromatic hydrocarbons (PAHs) See Appendix A See Appendix C
NIOSH IDLH: 1750 mg/m³ See: 1333864

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 prolonged exposure. This substance is possibly carcinogenic to humans. to be discussed at peer-review meeting 2B

PHYSICAL
PROPERTIES

Melting point: ca. 3550°C
Relative density (water = 1): 1.8-2.1
Solubility in water:
none

Auto-ignition temperature: above 500°C

ENVIRONMENTAL
DATA

N O T E S

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 the chemical composition. 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.
