Method
- Ethical approval:
- not specified
- Details on study design:
- The procedure followed in this study consisted of the exposure of an average number of ten persons, of mixed sexes, to a given concentration of solvent vapour for a period of 3 to 5 min, in a 1200 cubic foot gas cabinet.
After the exposure, each individual classified the effect of the vapour on the eyes, nose, and throat. The classifications were: no reaction, slightly irritating, and very irritating.
The odor was listed as absent, definite, moderate, strong, or overpowering.
Finally, each person was asked if he believed he could work in the atmosphere for an eight-hour day. - Exposure assessment:
- not specified
- Details on exposure:
- TYPE OF EXPOSURE: inhalation
EXPOSURE LEVELS: 100 - 150 ppm (corresponding to approx. 0.366 - 0.549 mg/L)
EXPOSURE PERIOD: 3 - 5 min
Results and discussion
- Results:
- Irritating to the throat at 100 ppm (equivalent to approx. 0.366 mg/L) and to the eyes and nose at 150 ppm (equivalent to approx. 0.549 mg/L).
The highest concentration which the majority of subjects estimated as acceptable for an 8-hour exposure was < 100 ppm (equivalent to approx. 0.366 mg/L).
Applicant's summary and conclusion
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
