Administrative data
First-aid measures
First Aid Measures: Make sure that the medical personnel knows the material they are dealing with and has all necessary protection measures available to
it.
Inhalation: If inhaled, remove to fresh air. Get medical attention immediately.
Skin contact: Remove contaminated clothing immediately. Flush contaminated skin with plenty of water with soap.
Eye contact: Flush eyes with plenty of water for at least 15 minutes. Get medical attention immediately.
Ingestion Do not give anything to drink. Induce vomiting. Get medical attention immediately.
Indications for physician: The first action of a physician taking care over an intoxicated person is assessing the appropriateness and effectiveness of first-aid.Further procedures depend on the status of the intoxicated patient. There is no specific antidote. Administer symptomatic treatment. Intoxicated persons should remain under medical care for at least 48 hours.
Fire-fighting measures
Extinguishing media: Fire foam and carbon dioxide and dry powder extinguishers, water (dispersed sprays).
Extinguishing media to be avoided for safety reasons: Not known.
Specific hazards: Drums exposed to flames or high temperature must be cooled with dispersed water spray and removed from the affected area if possible.
Special fire protection equipment for fire fighters: The personnel directly participating in fire-fighting operations should wear proper, light clothes, protecting the skin (gas proof) and be provided with equipment isolating the airways because of the toxic burning products, such as: hydrogen chloride, carbon monoxide and phosgene.
Additional Information: None
Accidental release measures
Individual protective measures: Do not inhale vapours. Avoid contact with substance.
Environmental protective measures: Prevent large quantities of product from entering into sewage, underground water, surface water and soil. Notify respective authorities in case of environmental contamination.
Cleanup: Stop the spill, if possible (e.g. seal up, place any damaged container inside an emergency container). Use a shovel or a scoop to collect substance to a closed container and handle or dispose of in accordance with respective regulations (see disposal considerations). Rinse contaminated surface thoroughly with water.
Handling and storage
Handling: Handle as directed on the label - instruction attached to container. Prepare working solution in volumes necessary for immediate use
only. Handle as directed by the generally accepted rules of industrial safety and hygiene. Keep away from unauthorised persons.
Storage: Store in original, air-tight closed containers, in dry and well ventilated warehouses in temperatures from 0ºC to 30ºC, away from food products, animal foods, food containers, heaters and open flame sources, away from unauthorised persons, especially children. Keep away from unauthorised persons. The substance stability period is 2 years of the date of manufacturing. After that date, substance can be used upon verification whether its parameters comply with technical requirements. In case of non-compliance, contact the manufacturer.
Special application: Not known.
