Concentration
- Location:
- construction site
- Substance or metabolite:
- substance
- Remarks:
- Isophorone diamine
- Conc.:
- <= 34 µg/m³ air
- Remarks on result:
- other: All samples taken at breathing level during mixing and working procedures were shown not to exceed 34 µg/m3 Isophorone diamine in air
Applicant's summary and conclusion
- Conclusions:
- Under the conditions of the study, all samples taken at breathing level during mixing and working procedures were shown not to exceed 34 µg/m3 Isophorone diamine in air.
- Executive summary:
Concentration of diamines in air during flooring/duct relining procedures with epoxybased resins were determined at construction sites and in a laboratory test by BG Bau.
Personally taken samples at breathing level during flooring at four construction sites, during laboratory test focused on mixing of epoxy based resin and during duct relining at five construction sites were collected and analysed regarding Isophorone diamine. All samples taken at breathing level during mixing and working procedures were shown not to exceed 34 µg/m3 Isophorone diamine in air.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
