This information will be made available to health professionals and others in accordance with the applicable provisions of this paragraph.
Inhalation: Remove patient to fresh air. Immediately call a first response, trained rescue squad. If patient is not breathing, administer artificial respiration. If breathing is difficult, administer oxygen.
Skin Contact: Remove all contaminated clothing and shoes. Wash affected skin areas with plenty of soap and water. Obtain immediate medical attention.
Eye Contact: Flush eyes including under the eyelids with plenty of water for at least fifteen minutes while keeping eyes wide open. Do not rub affected areas. Obtain immediate medical attention.
Ingestion: Remove patient to fresh air. Immediately call a first response, trained rescue squad. Do not induce vomiting unless directed by medical personnel. Never give anything by mouth to an unconscious person.
Suitable extinguishing media: Use media appropriate for surrounding fire such as foam, extinguishing powder, carbon dioxide or water spray. In case of fire, cool endangered containers with water spray.
Unsuitable extinguishing media: High pressure water jet.
Specific hazards in case of fire: May release toxic hydrogen cyanide fumes upon heating to dryness.
Special protective equipment and precaution for fire fighters: For fires in enclosed areas, wear self-contained breathing apparatus and full protective gear. Do not inhale combustion gases.
Personal precautions, protective equipment and emergency procedures: Wear appropriate skin, eye and respiratory protection. Do not eat, drink or smoke while cleaning up. Ensure adequate ventilation.
Methods and materials for containment and cleaning up: Wear appropriate personal protective gear including eye, skin and respiratory protection. Contain spilled material and collect for gold recovery by absorption or other suitable method. Flush spill area with water. Do not allow this material or its rinsings to enter storm or sanitary sewers or other waterways. (See also Section 13).
Environmental precautions: Prevent spills and rinsings from entering storm or sanitary sewers or other waterways and contact with soil.
Precautions for safe handling: Avoid contact with eyes. Avoid prolonged repeated skin contact and breathing mists or vapors. Use in well-ventilated area. Do not empty waste into sanitary drains.
Conditions for safe storage, including incompatibilities: Store in a cool, dry area. Use with adequate ventilation. Keep container tightly closed when not in use. Store only in the original container.
