TYPES OF HAZARD / EXPOSURE	ACUTE HAZARDS / SYMPTOMS	PREVENTION	FIRST AID / FIRE FIGHTING
FIRE	Not combustible. Gives off irritating or toxic fumes (or gases) in a fire.		In case of fire in the surroundings: use appropriate extinguishing media.
EXPLOSION

EXPOSURE		PREVENT DISPERSION OF DUST! AVOID ALL CONTACT!
Inhalation	Cough. Shortness of breath. Sore throat.	Local exhaust or breathing protection.	Fresh air, rest. Refer for medical attention.
Skin	Redness.	Protective gloves. Protective clothing.	Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention.
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. Diarrhoea. Nausea. Vomiting. Weakness.	Do not eat, drink, or smoke during work.	Rinse mouth. Refer for medical attention.

COBALT(II) ACETATE TETRAHYDRATE

ICSC: 1128

IMPORTANT DATA

PHYSICAL STATE; APPEARANCE:
RED CRYSTALS

CHEMICAL DANGERS:
The substance decomposes on heating producing irritating fumes. Reacts with strong oxidants causing fire and explosion hazard.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: (as Cobalt) 0.02 mg/mł as TWA A3 (ACGIH 2001). BEI 15 ug/l urine, B, 1 ug/l blood, B,Sq,

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. Lungs may be affected by repeated or prolonged exposure. The substance may have effects on the heart, thyroid, bone marrow, when ingested. This substance is possibly carcinogenic to humans.

PHYSICAL PROPERTIES

Melting point: 140°C
Density: 1.7 g/cm^3
Solubility in water: very good

ENVIRONMENTAL DATA

Bioaccumulation of this chemical may occur in seafood.

NOTES

Depending on the degree of exposure, periodic medical examination is indicated. Do NOT take working clothes home. Anyone who has shown symptoms of asthma due to this substance should avoid all further contact. The symptoms of asthma 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. The apparent melting point caused by loss of crystal water is given. The recommendations on this Card also apply to Cobalt (II) acetate anhydrous (CAS 71-48-7).
