Ingestion: Do not induce vomiting. In case of consciousness wash mouth with water and let drink some of

water. Seek medical advice. Keep patient at rest.

Fire-fighting measures

Suitable Extinguishing Media: Fire-extinguishing powder Dry sand carbon dioxide (CO2)

Unsuitable Extinguishing Media: Water Foam

Dangerous Combustion Products:

hydrogen chloride

carbon oxides

Protective equipment for firefighters: Wear self-contained breathing apparatus and fire protective suite.

Accidental release measures

Personal precautions: Wear chemical resistant protective suite. Avoid contact with skin, eyes and clothing. Do not

proceed against the wind direction. Keep people away from and upwind of spill/leak.

Environmental: Do not release on the soil or into drains.

Methods for cleaning: Cover with dry sand and take up mechanically. Keep in suitable, closed containers for

disposal.

Accidental Release: Records must be kept of all incidents involving uncontrolled leakage or spillage of material,

indicating in particular the amounts concerned, exposure of personnel and countermeasures

taken. Buildings, apparatus, and all items of equipment must be decontaminated and subsequently

inspected to ensure that no further risk remains.

All equipment and protective garments must be either decontaminated or properly contained

for disposal before leaving the area.

Handling and storage

Storage and Handling Precautions: Handle in closed system. Provide exhaust ventilation system in case of open handling of small

quantities. Open handling without suitable personal protective equipment must be

avoided. Keep container tightly closed in a dry, cool and well-ventilated place. Keep container

dry. Avoid formation of dust.

Conditions of storage: Protect against humidity

Do not store together with bases, amines

Technical measures/Precautions: Preferably handle in closed system.

Preventive Precautions (fire/explosion): Observe the usual precautionary measures required for chemicals with dust explosive

properties (Observe national regulations). Keep away from open flames, hot surfaces and

sources of ignition.
