TYPES OF HAZARD/ EXPOSURE

ACUTE HAZARDS/ SYMPTOMS

PREVENTION

FIRST AID/
FIRE FIGHTING

FIRE Not combustible but enhances combustion of other substances. Gives off irritating or toxic fumes (or gases) in a fire.
NO contact with combustibles andreducing agents.
In case of fire in the surroundings: all extinguishing agents allowed.
EXPLOSION Risk of fire and explosion on contact with combustible substances.


EXPOSURE
AVOID ALL CONTACT!
IN ALL CASES CONSULT A DOCTOR!
 •INHALATION Sore throat. Cough. Shortness of breath.
Local exhaust or breathing protection.
Fresh air, rest. Refer for medical attention.
 •SKIN Redness.
Protective gloves. Protective clothing.
First rinse with plenty of water, then remove contaminated clothes and rinse again.
 •EYES Redness. Pain.
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 take to a doctor.
 •INGESTION Abdominal pain. Nausea. Vomiting.
Do not eat, drink, or smoke during work. Wash hands before eating.
Rinse mouth. Give one or two glasses of water to drink. Refer for medical attention.

SPILLAGE DISPOSAL

STORAGE

PACKAGING & LABELLING

Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place. Do NOT absorb in saw-dust or other combustible absorbents. Do NOT let this chemical enter the environment. (Extra personal protection: P3 filter respirator for toxic particles.)
Separated from combustible and reducing substances. Well closed.

ICSC: 1397 Prepared in the context of cooperation between the International Programme on Chemical Safety & the Commission of the European Communities (C) IPCS CEC 1994. No modifications to the International version have been made except to add the OSHA PELs, NIOSH RELs and NIOSH IDLH values.

PHYSICAL STATE; APPEARANCE:
PALE RED POWDER.

PHYSICAL DANGERS:


CHEMICAL DANGERS:
The substance decomposes on heating producing toxic gases , including nitrogen oxides . Reacts with combustible substances causing fire hazard.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: (as Co) 0.02 mg/m3 as TWA A3 (confirmed animal carcinogen with unknown relevance to humans); BEI issued (ACGIH 2008).
MAK: (as Co) (Inhalable fraction) skin absorption (H); sensitization of respiratory tract and skin (Sah);
Carcinogen category: 2 Germ cell mutagen group: 3A
(DFG 2008).


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

INHALATION RISK:
Evaporation at 20°C is negligible; a nuisance-causing concentration of airborne particles can, however, be reached quickly.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is irritating to the eyes , the skin and the respiratory tract .

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Repeated or prolonged contact may cause skin sensitization. Repeated or prolonged inhalation exposure may cause asthma. The substance may have effects on the heart, thyroid and bone marrow , resulting in cardiomyopathy goiter and polycythemia. This substance is possibly carcinogenic to humans. Animal tests show that this substance possibly causes toxic effects upon human reproduction. Animal tests show that this substance possibly causes malformations in human babies.

PHYSICAL
PROPERTIES

Melting point (decomposes): 100-105°C
Density: 2.49
g/cm3
Solubility in water: soluble

ENVIRONMENTAL
DATA

See Notes.

N O T E S

Anyone who has shown symptoms of asthma due to this substance should avoid all further contact with this substance. Depending on the degree of exposure, periodic medical examination is indicated. Environmental effects from the substance have not been investigated but data on cobalt ion suggest that it may be hazardous to aquatic organisms. Also consult ICSC on cobalt salts such as 0783 - Cobalt(II) chloride.
