Fire-fighting measures

Extinguishing media
Suitable extinguishing agents:
CO2, sand, extinguishing powder. Do not use water.
BC powder
Carbon dioxide
Dry sand
For safety reasons unsuitable extinguishing agents: Water. Foam.
Avoid high pressure extinguishing media which could cause the formation of a potentially explosible dust-air mixture.

Special hazards arising from the substance or mixture: In case of fire, the following can be released:
Carbon monoxide (CO)
The possibility of formation of explosive dust/air mixtures under certain conditions should be basically considered during handling and processing.
Carbondioxide (CO₂)

Advice for firefighters
Protective equipment: Wear self-contained respiratory protective device.
Chemical resistant protective suit.
Under the protective suit a fire protective suit according to EN 469 should be applied.

Accidental release measures

Personal precautions, protective equipment and emergency procedures
Wear protective clothing.
Avoid contact with eyes and skin and clothes
Do not breathe dust.
Access only for trained personnel with personal protective equipment.
Use respiratory protective device against the effects of fumes/dust/ aerosol.
Avoid spillage of product into the environment.
Avoid formation of dust.
Implementation of further measures based on existing emergency plans.

Environmental precautions: Inform respective authorities in case of seepage into water course or sewage system.
Do not allow undiluted product or large quantities of it to reach ground water, water course or sewage system.

Methods and material for containment and cleaning up: Absorb with dry sand or silicate.
Pick up mechanically. If formation of dust cannot be avoided use respiratory filter device.
Dispose contaminated material as waste accordingly.

Discharge into waste water channels and biological treatment plants only after clearance with the operating company and in accordance with local Authority approval.

Exposure controls / personal protection

Control parameters
Additional information about design of technical facilities: Take care of sufficient ventilation. Avoid formation of dust.
Handle this material under exclusion of humidity.
Waste gases should be led into the atmosphere only via appropriate separators, scrubbers or incinerators.
Ingredients with limit values that require monitoring at the workplace: Not required.
DNEL/PNEC-values: According to Art. 17 and 18 of EU-Regulation 1907/2006 (REACH) this substance is used as isolated intermediate under strictly controlled conditions. Therefore no DNEL/PNEC is required.

Exposure controls: This product is exclusively dedicated for the application as isolated and transported intermediate under strictly controlled conditions according to Article 18 of Regulation EC 1907/2006 (REACH-Regulation).
Personal protective equipment
General protective and hygienic measures: Contaminated protective suit shall be cleaned before taking it off.
Keep away from foodstuffs, beverages and feed.
Wash hands before breaks and at the end of work.
Store protective clothing separately.
Respiratory protection: Particle filter. The filter grade (P1 - P3) has to be established depending on work-place related limit values and the actual exposition.
Protection of hands: Selection of the glove material on consideration of the penetration times, rates of diffusion and the degradation.
For the permanent contact gloves made of the following materials are suitable: The following materials are known from experience to be suitable for protection against undissolved solids: rubber.
Check for tightness before use.
Replace damaged gloves.
Eye protection:
Safety glasses
Body protection: Use dust-proof protective suit.
Selection of personal protective suits depending on amount and concentration of hazardous material and on possible exposition at the
working place.
Protection against thermal hazards: No specific measures required.
Limitation and supervision of exposure into the environment: Avoid spillage of product into the environment.
If possible use this material only in closed systems and devices. In case of open plant systems (sampling devices, filling and discharging, cleansing works etc.) use local exhaust and collecting trays. Follow emission limit values. Measures in case of unwanted emissions should
be established.
