Guidance on Safe Use
Administrative data
First-aid measures
- Inhalation: Remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Use oxygen as required, provided a qualified operator is present. Call a physician.
- Skin contact: Wash off immediately with plenty of water for at least 15 minutes. Take off contaminated clothing and shoes immediately. Wash contaminated clothing before re-use. First treatment with calcium gluconate paste. Call a physician.
- Eye contact: Rinse immediately with plenty of water, also under the eyelids, for at least 15 minutes. Call a physician. Ingestion : Do not induce vomiting without medical advice. Never give anything by mouth to an unconscious person. Call a physician.
- Notes to physician Treatment: Treat symptomatically.
Fire-fighting measures
- Flash point: not applicable
- Lower explosion limit: not applicable
- Upper explosion limit: not applicable
- Suitable extinguishing media: Water spray, Foam, Carbon dioxide (CO2), Dry powder
- Specific hazards during fire fighting: In case of fire hazardous decomposition products may be produced such as: Hydrogen fluoride, Toxic metal oxide fumes
- Special protective equipment for fire-fighters: In the event of fire and/or explosion do not breathe fumes. Wear self-contained breathing apparatus and protective suit. No unprotected exposed skin areas.
- Additional advice : Use extinguishing measures that are appropriate to local circumstances and the surrounding environment.
Accidental release measures
- Personal precautions: Wear personal protective equipment. Evacuate personnel to safe areas. Ensure adequate ventilation. Avoid dust formation. Do not swallow. Avoid breathing dust. Avoid contact with skin, eyes and clothing.
- Environmental precautions : Prevent further leakage or spillage if safe to do so. Do not let product enter drains. Do not flush into surface water or sanitary sewer system. Do not allow run-off from fire fighting to enter drains or water courses.
- Methods for cleaning up : Avoid dust formation. Sweep up and shovel into suitable containers for disposal.
Handling and storage
Handling
- Handling : Wear personal protective equipment. Keep container tightly closed. Containers which are opened must be carefully resealed and kept upright to prevent leakage. Use only in well-ventilated areas. Avoid dust formation. Do not swallow. Avoid breathing dust. Avoid contact with skin, eyes and clothing.
- Advice on protection against fire and explosion: Normal measures for preventive fire protection.
Storage
-Requirements for storage areas and containers: Keep containers tightly closed in a dry, cool and well-ventilated place. Keep away from heat and sources of ignition. Protect from physical damage. Store away from incompatible substances.
- Advice on common storage: Do not store together with: Acids
