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 and reducing 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 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. 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

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.)

EMERGENCY RESPONSE

STORAGE

Separated from combustible and reducing substances. Well closed.

COBALT(II) NITRATE HEXAHYDRATE

ICSC: 0784

IMPORTANT DATA

PHYSICAL STATE; APPEARANCE:
RED CRYSTALS.

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/mł as TWA; A3 (confirmed animal carcinogen with unknown relevance to humans); BEI issued (ACGIH 2000).
MAK: (Co and Co compounds) (Inhalable fraction) sensitization of respiratory tract and skin (Sah); Carcinogen category: 2; Germ cell mutagen group: 3A (DFG 2006).

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 harmful concentration of airborne particles can, however, be reached quickly when dispersed.

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, goitre 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

Decomposes below boiling point at 74°C
Melting point: 55°C
Density: 1.88 g/cmł
Solubility in water, g/100 ml at 0°C: 133.8

ENVIRONMENTAL DATA

See Notes.

NOTES

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. Card has been partially updated in August 2007: see Ingestion First Aid, Occupational Exposure Limits.
