Guidance on Safe Use
Administrative data
First-aid measures
General: Get medical attention if symptoms occur. Contaminated clothing to be placed in closed container until disposal or decontamination.
Inhalation: Move into fresh air and keep at rest.
Eye contact: In the event of contact with the eyes, rinse thoroughly with clean water. Continue to rinse for at least 15 minutes.
Skin contact: Remove contaminated clothing and shoes. Wash with soap and water.
Ingestion: Do not induce vomiting. Rinse mouth thoroughly.
Fire-fighting measures
Suitable extinguishing media: Foam. Carbon dioxide (CO2).
Unsuitable extinguishing media: Do not use water as an extinguisher. Halogens and halogenated compounds. Alkaline powders.
Special hazards : flammable. This product may generate hydrogen gas. A fire or explosion hazard arises since highly flammable gas (hydrogen) is released when it is in contact with : Alkalis and caustic products. Chemical compounds with mobile hydrogen, in the presence of metal salts and complexes.
Accidental release measures
Personal precautions, protective equipment and emergency procedures: Eliminate all sources of ignition. Use personal protective equipment. Keep away from Alkalis and caustic products.
Environmental precautions: Collect spillage. Do not discharge into drains, water courses or onto the ground.
Methods and material for containment and cleaning up: Use explosion-proof electrical/ventilating/lighting/…/equipment. Containers with collected spillage must be properly labelled with correct contents and hazard symbol. Container must be kept tightly closed. Suitable containers equipped with a degassing device.
Absorb with sand or other inert absorbent. Do NOT use products which are basic. To clean the floor and all objects contaminated by this material, use an appropriate solvent. Flush area with plenty of water. Incinerate in suitable combustion chamber.
Handling and storage
Precautions for safe handling: Use mechanical ventilation in case of handling which causes formation of vapors. Provide electrical earthing of equipment and electrical equipment usable in explosive atmospheres. Nitrogen blanketing of containers is required. Ground container and transfer equipment to eliminate static electric sparks. Do not mix with Incompatible materials.
Conditions for safe storage, including any incompatibilities: Avoid discharge into drains, water courses or onto the ground. Store in original tightly closed container equipped with a degassing device. Store in a cool, dry place with adequate ventilation. Keep away from incompatible materials, open flames, and high temperatures. Material should be stored under an inert atmosphere. Suitable containers: Steel drums coated with epoxy-resin.
