4. First Aid Measures
- Ingestion
- Do not induce vomiting; immediately call for medical help.
- Inhalation
- Supply fresh air or oxygen; call for doctor.
- In case of unconsciousness place patient stably in side position for transportation.
- Skin Contact
- Immediately wash with water and soap and rinse thoroughly.
- Eye Contact
- Rinse opened eye for several minutes under running water. Then consult a doctor.
- Other Information
- Immediately remove any clothing soiled by the product.
- Symptoms of poisoning may even occur after several hours; therefore medical observation for at least 48 hours after the accident.
- Remove breathing apparatus only after contaminated clothing have been completely removed.
- In case of irregular breathing or respiratory arrest provide artificial respiration.
5. Firefighting Measures
Suitable extinguishing equipment
- Fire
- Use fire extinguishing methods suitable to surrounding conditions.
- Large Fire
- CO₂, extinguishing powder or water spray. Fight larger fires with water spray or alcohol resistant foam.
- HAZCHEM
- Not available.
Special protective equipment and precautions for fire fighters
Mouth respiratory protective device.
6. Accidental Release Measures
- Personal precautions, protective equipment and emergency procedures
- Not available.
- Environmental precautions
- Inform respective authorities in case of seepage into water course or sewage system.
- Do not allow to enter sewers/ surface or ground water.
- Methods and materials for containment and clean up
- Dispose contaminated material as waste according to item 13.
- Ensure adequate ventilation.
7. Handling and Storage
- Precautions for safe handling
- Thorough dedusting.
- Ensure good ventilation/exhaustion at the workplace.
- Open and handle receptacle with care.
- Protect from heat and against electrostatic charges.
- Keep respiratory protective device available in case of fire.
- Conditions for safe storage
- Keep receptacle tightly sealed.
- Protect from heat and direct sunlight
8. Exposure Controls / Personal Protection
Exposure Standards
- Engineering controls
- Keep away from foodstuffs, beverages and feed.
- Immediately remove all soiled and contaminated clothing.
- Wash hands before breaks and at the end of work.
- Store protective clothing separately.
Personal protective equipment
- Eye and face protection
- None required.
- Skin protection
- Wear protective gloves.
- The glove material has to be impermeable and resistant to the product/ the substance/ the preparation.
- Due to missing tests no recommendation to the glove material can be given for the product/ the preparation/ the chemical mixture.
- Selection of the glove material on consideration of the penetration times, rates of diffusion and the degradation
- 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 through time has to be found out by the manufacturer of the protective gloves and has to be observed.
- Body protection
- Lab coat
- Respiratory protection
- In case of brief exposure or low pollution use respiratory filter device. In case of intensive or longer exposure use respiratory protective device that is independent of circulating air.
