Guidance on Safe Use

First-aid measures

General information: Symptoms of poisoning may even occur after several hours; therefore medical observation for at least 48 hours after the accident.

After inhalation: Supply fresh air and to be sure call for a doctor. In case of unconsciousness place patient stably in side position for transportation. In case of irregular breathing or respiratory arrest provide artificial respiration.

After skin contact: Take off all contaminated clothing. Immediately wash with water and soap and rinse thoroughly. If skin irritation continues, consult a doctor.

After eye contact: Protect unharmed eye. Rinse opened eye for several minutes under running water. Remove contact lenses, if present and easy to do. Continue rinsing. Seek medical treatment.

After swallowing: Rinse out mouth and then drink plenty of water. Call for a doctor immediately.

Fire-fighting measures

Suitable extinguishing agents: Water spray; fire-extinguishing powder; foam; carbon dioxide (CO2).

For safety resons unsuitable extinguishing agents: Water with full jet.

Special hazards arising from the substance or mixture: In case of fire, the following can be released: Carbon monoxide (CO); Carbon dioxide (CO2).

Advice for fire fighter:

      Protective equipment: In case of fire, wear self-contained respiratory protective device.

      Additional information:

      - Cool endangered receptacles with water spray.

      - Move undamaged containers from immediate hazard area if it can be done safely.

      - Collect contaminated fire fighting water separately. It must not enter the sewage system.

      - Dispose of fire debris and contaminated fire fighting water in accordance with official regulations.

Accidental release measures

Person-related safety precautions: Wear protective equipment. Keep unprotected persons away. Avoid formation of dust.

Measures for environmental protection: Do not allow product to reach sewage system or any water course. Do not allow to penetrate the ground/soil. Inform respective authorities in case of seepage into water course, soil or sewage system

Measures for cleaning/collecting: Avoid dust formation. Remove mechanically, placing in appropriate containers for disposal. Use approved industrial vacuum cleaner for removal. Ensure adequate ventilation.

Handling and storage

- Handling:

Information for safe handling: Ensure good ventilation/exhaustion at the workplace. Prevent formation of dust. Any unavoidable deposit of dust must be regularly removed. Avoid contact with eyes or skin. Wear personal protective equipment. Avoid breathing dust/fume/gas/mist/vapours/spray.

Information about fire - and explosion protection: Keep ignition sources away - Do not smoke.

· Storage:

Requirements to be met by storerooms and receptacles: Store only in the original container.

Information about storage in one common storage facility: Keep away from food, drink and animal feeding stuffs. Store away from flammable substances. Do not store together with oxidising and acidic materials. Store away from bases. Store away from reducing agents.

Further information about storage conditions: Store in cool, dry conditions in well sealed containers. Ensure that local, federal and national legislation on storage conditions are observed.

Exposure controls / personal protection

Additional information about design of technical facilities:

Technical measures and the application of adequate working methods take priority over the use of personal protection equipment.

Control parameters:

Ingredients with limit values that require monitoring at the workplace: Not required.

Exposure controls:

Personal protective equipment:

- General protective and hygienic measures: Do not eat, drink, smoke or sniff while working. Ensure that washing facilities are available at the work place. Wash hands before breaks and at the end of work. Store protective clothing separately.

- Respiratory protection: If technical suction or ventilation measures are not possible or are insufficient, protective breathing apparatus must be worn.

The filter class must be suitable for the maximum contaminant concentration (gas/vapour/aerosol/particulates) that may arise when handling the product. If the concentration is exceeded, a self-contained breathing apparatus must be used!

Short term filter device:

Particulate filter (EN 143)

- Protection of hands: Tested protective gloves are to be worn. When handling chemical substances, chemical protective gloves must be worn with CE label including a four digit code. Type of chemical protective gloves to choose depends on the concentration and quantity of dangerous substances as well as on work place specifications. In the cases of special applications, it is recommended to check the chemical resistance with the manufacturer of the gloves. The glove material has to be impermeable and resistant to the product/ the substance/ the preparation. Selection of the glove material on consideration of the penetration times, rates of diffusion and the degradation. (EN 374)

· Material of gloves: The selection of the suitable gloves does not only depend on the material, but also on further marks of quality and varies from manufacturer to manufacturer.

· Penetration time of glove material: The exact break trough time has to be found out by the manufacturer of the protective gloves and has to be observed.

- Eye/face protection: Safety glasses (EN 166)

- Body protection: Protective clothing. Selection of body protection depends on the concentration and quantity of dangerous substances as well as on work place specifications.

Limitation and supervision of exposure into the environment: Dumping into the environment must be prevented.
