IV FIRE AND EXPLOSION H AZARDS DATA
Flash Point (Method used): N/A Autoignition Temperature: N/A
Flam mab le Limits: Upper: N/A Lower: N/A Flam mab ility: Non-flam ma ble
Extingu ishing Media: Use suitable extinguishing media for surrounding materials and type of fire.
Special Fire Fighting Procedures: Firefighters must wear full face, self-contained breathing apparatus with full protective clothing
to prevent contact with skin and eyes. Fumes from fire are hazardous. Isolate runoff to prevent environmental pollution.
Unusual Fire & Explosion Hazard: Contact with strong acids form flammable hydrogen gas. Ignites on contact with bromine
pentafluoride.
V HEALTH HAZARD INFORMATION
Primary Ro utes of exposure: Inhalation, in gestion, skin or ey e con tact.
Effects of Over Expo sure:
Cobalt has a low toxicity by ingestion. Ingestion of soluble salts produces nau sea and vom iting by local irritation. In
animals, administration of cobalt salts produces an increase in the total red cell mass of the blood. In humans, a single case of
poisoning with liver kidney damage has been attributed to cobalt. Locally, cobalt has been shown to produce dermatitis and
investigators have been able to demonstrate a hypersensitivity of the skin to cobalt. There have been reports of hematologic, digestive
and p ulmonary chang es in hum ans.
Acute E ffects:
Inhalation: May cause shortness of breath, coughing, weight loss and pulmonary damage.
Ingestion: Moderately toxic by ingestion. May cause acute cobalt poisoning.
Skin : May cause irritation.
Eye: May cause irritation and possibly damage the cornea.
Chro nic Effects:
Inhalation: May cause diffuse nodular fibrosis and respiratory sensitivity.
Ingestion: No chronic health effects recorded.
Skin : May cause allergic sensitization and derm atitis.
Eye: No chronic health effects recorded.
Target Organs: May affect the respiratory and pulmonary system.
Carcino genicity: NTP: No IARC: No OSHA: No
Medical Conditions Generally Aggravated by Exposure: Pre-existing resp iratory or skin disorde rs.
EMERG ENCY AND FIRST AID PROCEDURES:
INHALATION: Remove victim to fresh air, keep warm and quiet, give oxygen if breathing is difficult and seek medical attention.
INGESTION: Give 1-2 glasses of milk or water and induce vomiting, seek medical attention (Never induce vomiting or give
anything by mou th to an unconscious p erson).
SK IN: Remove contaminated clothing, brush material off skin, wash affected area with mild soap and water, seek medical attention.
EYE: Flush eyes with lukewarm water, lifting upper and lower eyelids, for at least 15 minutes. Seek medical attention.
