TYPES OF HAZARD / EXPOSURE	ACUTE HAZARDS / SYMPTOMS	PREVENTION	FIRST AID / FIRE FIGHTING
FIRE	Combustible. Gives off irritating or toxic fumes (or gases) in a fire.	NO open flames. NO contact with oxidants.	Powder, water spray, foam, carbon dioxide.
EXPLOSION

EXPOSURE		PREVENT DISPERSION OF DUST! STRICT HYGIENE!
Inhalation	Cough. Sore throat. Shortness of breath. Laboured breathing. Symptoms may be delayed (see Notes).	Local exhaust or breathing protection.	Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer for medical attention.
Skin	Redness. Pain.	Protective gloves.	Remove contaminated clothes. Rinse skin with plenty of water or shower.
Eyes	Pain. Redness.	Safety goggles, or eye protection in combination with breathing protection if powder.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
Ingestion	Abdominal pain. Burning sensation in the throat and chest. Nausea.	Do not eat, drink, or smoke during work.	Rinse mouth. Give plenty of water to drink. Refer for medical attention.

COBALT CARBONYL

ICSC: 0976

IMPORTANT DATA

PHYSICAL STATE; APPEARANCE:
ORANGE CRYSTALS.

CHEMICAL DANGERS:
The substance decomposes on warming or under the influence of air producing toxic fumes of carbon monoxide and cobalt (see ICSC 0023, ICSC 0785). Reacts with oxidants causing fire hazard.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: (as Co) 0.1 mg/mł as TWA; (ACGIH 2004).
MAK not established.

ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation and by ingestion.

INHALATION RISK:
A harmful contamination of the air will be reached rather slowly on evaporation of this substance at 20°C.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is irritating to the eyes and the skin. The substance is severely irritating to the respiratory tract. Inhalation of may cause lung oedema (see Notes). The effects may be delayed. Medical observation is indicated.

PHYSICAL PROPERTIES

Decomposes below boiling point at 52°C
Melting point: 51°C
Density: 1.7 g/cmł
Solubility in water: none
Vapour pressure, Pa at 20°C: about 200

ENVIRONMENTAL DATA

NOTES

Do NOT take working clothes home. 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 is therefore essential. Immediate administration of an appropriate inhalation therapy by a doctor or a person authorized by him/her, should be considered. Environmental effects from the substance have not been investigated.
