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. Wheezing.  Use local exhaust or breathing protection.  Fresh air, rest. Refer for medical attention. 
Skin   Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse skin with plenty of water or shower. 
Eyes Redness. Pain.  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 Abdominal pain. Diarrhoea. 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

IMPORTANT DATA
Physical State; Appearance
PALE BLUE HYGROSCOPIC POWDER. TURNS PINK ON EXPOSURE TO AIR AND MOISTURE. 

Physical dangers
No data. 

Chemical dangers
Reacts with oxidants. 

Occupational exposure limits
TLV (as Co): 0.02mg/m³ as TWA; A3 (confirmed animal carcinogen with unknown relevance to humans); BEI issued; (ACGIH 2012).
MAK (inhalable fraction): Carcinogen category: 2; Germ cell mutagen group: 3A; Skin absorption (H); Sensitization of respiratory tract and skin (SAH); (DFG 2012). 

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

Inhalation risk
A harmful concentration of airborne particles can be reached quickly when dispersed. 

Effects of short-term exposure
The substance is irritating to the eyes. 

Effects of long-term or repeated exposure
Repeated or prolonged contact may cause skin sensitization. Repeated or prolonged inhalation may cause asthma. Ingestion may cause effects on the heart, bone marrow and thyroid. This substance is possibly carcinogenic to humans. Animal tests show that this substance possibly causes toxic effects upon human reproduction.

The substance is very toxic to aquatic organisms. The substance may cause long-term effects in the aquatic environment. It is strongly advised not to let the chemical enter into the environment. 

NOTES
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.
Depending on the degree of exposure, periodic medical examination is suggested.
Do NOT take working clothes home.
The recommendations on this Card also apply to Cobalt (II) chloride hydrates: Cobalt (II) chloride hexahydrate (CAS 7791-13-1), Cobalt (II) chloride dihydrate (CAS 14216-74-1).
