Results and discussion

Results:

Results: At present DEA is produced in one production plant and is further processed within 8 other operations and plants at the BASF SE.
The results of the 53 measurements are summarized as follows:
Overall Range of values: < 0.019 to 0.062 mg/m3
Medium value: 0.011 mg/m3
50% percentile: 0.003 mg/m3
90% percentile: 0.035 mg/m3
95% percentile: 0.051 mg/m3

Highest value for production plant: 0.026 mg/m3
Highest value at filling station: 0.062 mg/m3

No detailed differentiation was considered necessary since all measured values were far below the MAK-value and about 90 % of all recorded values were below limits of detection.

Precautions taken at the production plant:
DEA is handled in technically closed processes at all plants and operations. Short-term tasks showing in general a potential for exposure are limited to sample taking, analytical work, filter changes or filling operations.   Direct skin contact is avoided by protective gloves (nitrile rubber or PVC).
