First Aid Measures

Ingestion
If swallowed, wash out mouth with water provided person is conscious. Call a physician.
Ingestion
May be harmful if ingested.
Ingestion
Rise mouth. DO NOT INDUCE VOMITING. Give a glass of water to drink and transport to hospital. If unwanted vomiting occurs ensure patients' posture does not cause inhalation of liquid. Give more water to wash down throat and gullet. Never give anything by mouth to an unconscious person. Place in a coma position and maintain respiration.
Inhalation
Material is irritating to mucous membranes and upper respiratory tract. May be harmful if inhaled.
Inhalation
Move patient to fresh air. Monitor for respiratory distress. If cough or difficulty breathing develops, evaluate for respiratory tract irritation, bronchitis, or pneumonitis. Administer oxygen and assist ventilation as required. Treat bronchospasm with beta2 agonist and corticosteroid aerosols.
Inhalation
If inhaled, remove to fresh air. If not breathing give artificial respiration. If breathing is difficult, give oxygen.
Skin
In case of contact, immediately wash skin with soap and copious amounts of water. Remove contaminated clothing and shoes. Call a physician.
Skin
Remove contaminated clothing and wash exposed area thoroughly with soap and water. A physician should examine the area if irritation or pain persists.
Skin
Causes skin irritation. May be harmful if absorbed through the skin.
Eyes
Causes irritation
Eyes
In case of contact with eyes, flush with copious amounts of water for at least 15 minutes. Assure adequate flushing by separating the eyelids with fingers. Call a physician.
Eyes
Irrigate exposed eyes with copious amounts of tepid water for at least 15 minutes. If irritation, pain, swelling, lacrimation, or photophobia persist, the patient should be seen in a health care facility.

Handling and Storage

Storage
The product is a class C1 combustible liquid and should be stored accordingly. Keep containers closed when not in use. Do not store next to boilers.
Handling
Wash thoroughly after handling. Do not eat, drink or smoke whilst handling the product. Handle according to good industrial hygiene and safety practice. Avoid unnecessary exposure. Remove material from eyes, skin and clothing. Wash contaminated equipment before storing or reusing.

Hazards Identification

Inhalation
High vapour concentrations are irritating to the eyes and the respiratory tract may cause headache and dizziness, and are anaesthetic and may have other central nervous system effects.
Skin
May cause irritation and de-fatting of skin.
Eyes
The concentrated product is liable to cause redness and pain.
Ingestion
Ingestion or inhalation of cobalt causes nausea, vomiting, diarrhea, and colicky abdominal pain.
Hazards
Emits toxic fumes under fire conditions.

Exposure Controls/Personal Protection

Personal Protection
Compatible chemical-resistant gloves. Chemical safety goggles. Protective clothing.
Personal Protection
Use chemical safety goggles whenever there is a danger of material contacting the eyes. Wear rubber nitrile gloves, protective clothing and boots.
Respirators
Use respirators and components tested and approved under appropriate government standards such as NIOSH (US) or CEN (EU). Where risk assessment shows air-purifying respirators are appropriate use a full-face respirator with multi-purpose combination (US) or type ABEK (EN 14387) respirator cartridges as a backup to engineering controls. If the respirator is the sole means of protection, use a full-face supplied air respirator.
Respirators
When airbourne exposure limit and/or comfort levels may be exceeded use a SA approved respirator consistent with the airbourne concentrations. When using organic chemical cartridges ensure that the cartridges are correct for the potential air contamination and are in good working order.
Exposure Effects
May cause allergic reaction.
Exposure Effects
Prolonged or repeated contact may cause dermatitis.
Exposure limit(s)
OSHA: PEL (8 h TWA): 0.1 mg/m3.

Fire Fighting Measures

Flash Point
90
Fire Fighting
Extinguish with water spray, carbon dioxide, dry chemical powder or appropriate foam. Wear self-contained breathing apparatus and protective clothing to prevent contact with skin and eyes.
Fire Fighting
Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Use agent most appropriate to extinguish fire.
Upper exp. limit
6
Lower exp. limit
1
Fire Potential
The product is a class C1 combustible liquid. Flash point: >61 deg C.

Accidental Release Measures

Small spills/leaks
Absorb on sand or vermiculite and place in closed containers for disposal. Ventilate area and wash spill site after material pickup is complete.
Small spills/leaks
Clean up personnel should wear full protective clothing including self contained breathing apparatus if risk of inhalation of high concentrations of mists/vapours. The area in which the spill has occurred may be slippery. Avoid secondary accidents and clean up immediately. Eliminate all sources of igntion. Contain large volumes of spilt material. Absorb on sand, earth or other chemical absorbent. Collect and seal in properly labelled drums for disposal.
