water jet .

Special hazards arising from the substance or mixture
Risk of hazardous gasses or fumes in the event of fire.

Advice for firefighters
Special protective equipment for fire fighting:
Use respiratory protection independent of recirculated air. Use tightly fitting chemical protection suit (see section Exposure controls/personal protection).
General information:
Dispose of combustion residue and extinguishing water in accordance with regulations and local bye-laws.

Accidental release measures

Personal precautions, protective equipment and emergency procedures
Avoid dust formation. Do not breathe dust. Avoid contact with eyes and skin. Wear personal protection equipment (see section Exposure controls/personal protection).

Environmental precautions
Cover any spilled material in accordance with regulations to prevent dispersal by wind. Prevent material from entering surface
waters, drains or sewers and soil. Retain contaminated water/extinguishing water.

Methods and material for containment and cleaning up
Take up mechanically and dispose of according to local/state/federal regulations. Avoid formation of dust and dust deposition.
Clean up with plenty of water.

Reference to other sections
Relevant information in other sections has to be considered. This applies in particular for information given on personal protective
equipment (section Exposure controls/personal protection) and on disposal (section Disposal considerations).

Exposure controls
Exposure in the work place limited and controlled
General protection and hygiene measures:
Do not breathe dust. Do not eat, drink or smoke when handling. Application of skin cream recommended to ensure optimum
protection of skin. Remove contaminated, soaked clothing immediately.
Personal protection equipment:
Respiratory protection
In case of dust formation: fine dust mask P2 .
Hand protection
protective gloves . At any sign of decay or chemical permeability remove gloves immediately and replace. The selection of
appropriate gloves not only depends on the material, but also on other quality characteristics, and may vary depending on the
manufacturer. Please observe information from your glove supplier in terms of permeability and breakthrough time.
Eye protection
tight fitting protective goggles . Provide work station with eye bathing equipment.
Skin protection
antistatic working shoes .

Exposure to the environment limited and controlled
Prevent material from entering surface waters and soil. Normally neutralisation is required before waste water is introduced into
purification plants. Do not introduce large amounts into purification plants.
