Materials and methods
Test material
- Reference substance name:
- Tetramethylenediamine
- EC Number:
- 203-782-3
- EC Name:
- Tetramethylenediamine
- Cas Number:
- 110-60-1
- Molecular formula:
- C4H12N2
- IUPAC Name:
- butane-1,4-diamine
Constituent 1
Method
- Ethical approval:
- not applicable
- Details on study design:
- During Turn Around activities at the DAB-fabriek the installation is opened up for maintenance activities.
During these maintenance activities potential exposure to1,4-di aminobutane (DAB) has been measured (local, stationary measurements in the air). - Exposure assessment:
- measured
Results and discussion
- Results:
- All but one measurement were below the analytical detection level (0.01-0.03 mg/m3).
One measurement =0.03 mg/m3
Applicant's summary and conclusion
- Conclusions:
- All but one measurement were below the analytical detection level (0.01-0.03 mg/m3).
One measurement =0.03 mg/m3
These concentrations measured in areas where people work, are fare below the DNEL (7 mg/m3). - Executive summary:
During a turn around (maintenace activities) at the DAB plant, stationary measurements in air were performed.
All but one measurement were below the analytical detection level (0.01-0.03 mg/m3).
One measurement =0.03 mg/m3
These concentrations measured in areas where people work, are fare below the DNEL (7 mg/m3).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
