CARBON BLACK	ICSC: 0471 (April 2017)
Furnace black Acetylene black Carbon soot

CAS #: 1333-86-4

UN #: see Notes

EC Number: 215-609-9

	ACUTE HAZARDS	PREVENTION	FIRE FIGHTING
FIRE & EXPLOSION	Combustible. Finely dispersed particles form explosive mixtures in air.	NO open flames. NO contact with hot surfaces. Prevent deposition of dust. Closed system, dust explosion-proof electrical equipment and lighting.	Use powder, water spray, foam, carbon dioxide. In case of fire: keep drums, etc., cool by spraying with water.

PREVENT DISPERSION OF DUST! AVOID ALL CONTACT!
	SYMPTOMS	PREVENTION	FIRST AID
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	CLASSIFICATION & 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.	According to UN GHS Criteria WARNING Suspected of causing cancer if inhaled May cause damage to lungs through prolonged or repeated exposure if inhaled Transportation UN Classification
STORAGE
Well closed. Separated from food and feedstuffs. See Chemical Dangers.

PHYSICAL & CHEMICAL INFORMATION

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.

Formula: C
Atomic mass: 12
Melting point: ≈3550°C
Relative density (water = 1): 1.8-2.1
Solubility in water: none
Auto-ignition temperature: >500°C

EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by inhalation. Effects of short-term exposure May cause mechanical irritation.	Inhalation risk A harmful concentration of airborne particles can be reached quickly when dispersed. Effects of long-term or repeated exposure Lungs may be affected by repeated or prolongated exposure. This substance is possibly carcinogenic to humans.

EXPOSURE & HEALTH EFFECTS

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

Effects of short-term exposure
May cause mechanical irritation.

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

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

OCCUPATIONAL EXPOSURE LIMITS
TLV: (inhalable fraction): 3 mg/m³, as TWA; A3 (confirmed animal carcinogen with unknown relevance to humans). MAK: (inhalable fraction): carcinogen category: 3

ENVIRONMENT

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. Depending on the process of manufacture, there are variations in their chemical compositions. Polyaromatic hydrocarbons (PAH) are reportedly present in some carbon blacks. 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.
