EC number: 270-659-9 | CAS number: 68475-76-3 A complex combination of finely divided inorganic particles separated from the exit gases formed during the manufacture of Portland cement. The flue dust consists of uncalcined raw materials along with partially calcined materials. Some Portland cement clinker is usually included. The major constituents of kiln dust are calcium carbonate, clays, shales, quartz and sulfate salts. The following materials may also be present:@Dolomite@Ca(OH)2@Feldspars@CaSO4@Fly ash@KCl@Iron oxides@K2CO3@CaF2@K2SO4@CaO@Na2SO4@Glasses of SiO2, Al.s@Portland cement chemicals [659
Endpoint summary

Description of key information
Flue Dust is considered to be irritating to skin and the respiratory system and entails a risk of serious damage to the eye.
Key value for chemical safety assessment
Skin irritation / corrosion
Endpoint conclusion
- Endpoint conclusion:
- adverse effect observed (irritating)
Eye irritation
Endpoint conclusion
- Endpoint conclusion:
- adverse effect observed (irritating)
Respiratory irritation
Endpoint conclusion
- Endpoint conclusion:
- adverse effect observed (irritating)
Additional information
From in vitro studies on skin irritation and skin corrosion it is concluded that Flue Dust is irritative to skin, but not corrosive to skin.
From an in vitro study on eye irritation it is concluded that Flue Dust is highly irritating to the eye.
From human data it is concluded that Flue Dust is irritating to the respiratory system.
Effects on skin irritation/corrosion: irritating
Effects on eye irritation: highly irritating
Effects on respiratory irritation: irritating
Justification for classification or non-classification
Based on the result from an experimental Klimesch 1 in vitro study on Flue Dust and on read-across to Portland cement, Flue Dust requires classification as irritating to skin. CLP: Skin Irritation, Category 2, H315 - Causes skin irritation; EU: Xi, R38 "Irritating to skin"
Based on the result from an experimental Klimesch 1 in vitro study on Flue Dust and on read-across to Portland cement, Flue Dust requires classification as severely irritating to eye. CLP: Eye Damage, Category 1, H318 - Causes serious eye damage; EU: Xi, R41 "Risk of seriuos eye damages"
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
