	ACUTE HAZARDS	PREVENTION	FIRE FIGHTING
FIRE & EXPLOSION	Self-heating. May ignite on exposure to air. Combustible. Gives off irritating or toxic fumes (or gases) in a fire.	NO open flames. NO contact with oxidizing agents.	Use water spray, powder, foam, carbon dioxide.

PREVENT DISPERSION OF DUST! STRICT HYGIENE!
	SYMPTOMS	PREVENTION	FIRST AID
Inhalation	Sore throat. Cough. Shortness of breath. Laboured breathing.	Use local exhaust or breathing protection.	Fresh air, rest. Half-upright position. Refer immediately for medical attention.
Skin	Redness. Pain.	Protective gloves. Protective clothing.	Remove contaminated clothes. Rinse and then wash skin with water and soap.
Eyes	Pain. Redness.	Wear safety goggles or eye protection in combination with breathing protection.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Ingestion	Sore throat. See Notes.	Do not eat, drink, or smoke during work.	Rinse mouth. Give one or two glasses of water to drink. Refer for medical attention .

SPILLAGE DISPOSAL	CLASSIFICATION & LABELLING
Evacuate danger area! Consult an expert! Personal protection: self-contained breathing apparatus. Sweep spilled substance into covered sealable containers. If appropriate, moisten first to prevent dusting. Then store and dispose of according to local regulations.	According to UN GHS Criteria Self-heating; may catch fire Fatal if inhaled Harmful if swallowed May cause respiratory irritation See Notes Transportation UN Classification UN Hazard Class: 6.1; 4.2; UN Pack Group: I
STORAGE
Fireproof. Separated from oxidants. Well closed. Refer to the manufacturer's instructions for proper storage conditions.
PACKAGING
Airtight. Unbreakable packaging. Put breakable packaging into closed unbreakable container. Do not transport with food and feedstuffs.

COBALT CARBONYL

ICSC: 0976

PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance ORANGE CRYSTALS. Physical dangers Chemical dangers Decomposes on warming. Decomposes under the influence of air. This produces toxic fumes of carbon monoxide and cobalt. Reacts with oxidants. This generates fire hazard.	Formula: C₈O₈Co₂ / (OC)₃Co(CO)₂Co(CO)₃ Molecular mass: 341.9 Decomposes at 52°C Melting point: 51°C Density (at 20°C): 1.7 g/cm³ Solubility in water at 20°C: none Vapour pressure, Pa at 20°C: ~ 200

EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by inhalation and by ingestion. Effects of short-term exposure The substance is irritating to the eyes and skin. The substance is severely irritating to the respiratory tract. Inhalation may cause lung oedema. See Notes. The effects may be delayed. Medical observation is indicated.	Inhalation risk A harmful contamination of the air will be reached rather slowly on evaporation of this substance at 20°C; on dispersing, however, much faster. Effects of long-term or repeated exposure

EXPOSURE & HEALTH EFFECTS

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

Effects of short-term exposure
The substance is irritating to the eyes and skin. The substance is severely irritating to the respiratory tract. Inhalation may cause lung oedema. See Notes. The effects may be delayed. Medical observation is indicated.

Inhalation risk
A harmful contamination of the air will be reached rather slowly on evaporation of this substance at 20°C; on dispersing, however, much faster.

Effects of long-term or repeated exposure

OCCUPATIONAL EXPOSURE LIMITS
TLV: (as Co): 0.1 mg/m³, as TWA

ENVIRONMENT

NOTES
The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation are therefore essential. Health effects of exposure to the substance have not been investigated adequately. Several manufacturers label this substance for other effects - including the possibility of allergic skin reactions, cancer, reproductive effects, specific target organ toxicity (following repeated exposure) or long-term aquatic hazard - but sufficient data to support these GHS classifications were not found.
