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.
