TYPES OF HAZARD / EXPOSURE	ACUTE HAZARDS / SYMPTOMS	PREVENTION	FIRST AID / FIRE FIGHTING
FIRE	Gives off irritating or toxic fumes (or gases) in a fire. See Notes.	NO open flames.	Water spray, powder.
EXPLOSION	Finely dispersed particles form explosive mixtures in air.	Prevent deposition of dust; closed system, dust explosion-proof electrical equipment and lighting.	In case of fire: keep drums, etc., cool by spraying with water.

EXPOSURE		PREVENT DISPERSION OF DUST! STRICT HYGIENE!
Inhalation	Cough. Shortness of breath. Sore throat. Wheezing.	Local exhaust or breathing protection.	Fresh air, rest. Refer for medical attention.
Skin	Redness. Pain.	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 if powder.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
Ingestion	Diarrhoea. Weakness.	Do not eat, drink, or smoke during work. Wash hands before eating.	Rinse mouth. Refer for medical attention.

SPILLAGE DISPOSAL	PACKAGING & LABELLING
Remove all ignition sources. Sweep spilled substance into sealable containers. Carefully collect remainder, then remove to safe place. (Extra personal protection: P2 filter respirator for harmful particles).	UN Hazard Class: 4.1 UN Pack Group: III

EMERGENCY RESPONSE	STORAGE
Transport Emrgency Card: TEC (R)-41G15. NFPA Code: H 1; F 2; R 0	Separated from strong oxidants. Well closed.

IMPORTANT DATA
Physical State; Appearance BROWN AMORPHOUS OR BLUISH-RED SOLID. Physical dangers Dust explosion possible if in powder or granular form, mixed with air. Chemical dangers Upon heating, toxic fumes are formed. Reacts with strong oxidants. Occupational exposure limits TLV not established.	Routes of exposure The substance can be absorbed into the body by inhalation of its aerosol and by ingestion. Effects of short-term exposure The aerosol irritates the eyes and the respiratory tract. Effects of long-term or repeated exposure Repeated or prolonged contact may cause skin sensitization.

PHYSICAL PROPERTIES	ENVIRONMENTAL DATA
Melting point: 140°C Density: 0.9 g/cm³ Solubility in water: none Auto-ignition temperature: 276°C

NOTES

Cobalt naphthenate is used as a solution usually in mineral oils and spirits: 6% (cobalt) solution; boiling point: >150°C; specific gravity (water=1): 0.94-0.98; vapour density (air=1): 4.9.
Health effects of exposure to the substance have not been investigated adequately.
