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! STRICT HYGIENE!

 •INHALATION Cough. Shortness of breath. Wheezing.
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.
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.
Do not eat, drink, or smoke during work.
Rinse mouth. Give one or two glasses of water to drink. Refer for medical attention.
SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place. Do NOT let this chemical enter the environment.
Dry. Separated from strong oxidants. Store in an area without drain or sewer access.
Do not transport with food and feedstuffs.

PHYSICAL STATE; APPEARANCE:
PALE- BLUE , HYGROSCOPIC POWDER . TURNS PINK ON EXPOSURE TO AIR AND MOISTURE.

PHYSICAL DANGERS:


CHEMICAL DANGERS:
Reacts with oxidants causing fire and explosion 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 2004).
MAK: (Inhalable fraction) skin absorption (H); sensitization of respiratory tract and skin (Sah);
Carcinogen category: 2 Germ cell mutagen group: 3A


ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its aerosol 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 exposure may cause asthma. The substance may have effects on the heart, thyroid and bone marrow . This substance is possibly carcinogenic to humans. Animal tests show that this substance possibly causes toxic effects upon human reproduction.

Environmental Hazard placard The substance is toxic to aquatic organisms.
N O T E S
Depending on the degree of exposure, periodic medical examination is suggested. 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. Anyone who has shown symptoms of asthma due to this substance should avoid all further contact with this substance. 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).
