EC number: 294-409-3 | CAS number: 91722-09-7 Substance formed during processing of liquid steel or during production of iron castings. Consists primarily of fused silicates and trace elements as oxides as well as trace of alloying elements.
The possible allergenic activities of slags, steelmaking, converter (BOS) and crushed stones from a quarry in the vicinity of Serra, Brasilia, were tested according to the OECD TG 406 Skin Sensitisation Test.
For induction, 10 Guinea pigs were exposed to the wetted substance 10 times topical applications under occlusive dressing for 48 h. After a 7 day rest phase, the challenge phase consisted of a single topical application (48 h).
No visible cutaneous reactions and no intolerance reaction was recorded in the challenge phase, and no reaction was recorded in the negative controls.
Slags, steelmaking, converter (BOS) and the crushed stone tested, are not
sensitising and do not need to be classified as skin sensitizers. No signal word and no hazard statement are required.
