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 activity of slags,
ferrous metal, blast furnace (air cooled - ABS), granular (8-11 mm) was
tested according to OECD 406 and NF EN ISO 10993-10 (February 2003)
concerning biological evaluation of medical devices: Tests for
irritation and delayed-type hypersensitivity.Slag leachate was prepared
by DIN 38414 -4 DEV S-4 by leaching for 24 h at a liquid/solid ratio of
10/1. For indcution, 21 Guinea pigs were exposed to the leachate in
triplicate topical applications under occlusive dressing for 6 h, at
100%. After a 14-day rest phase, the challenge phase consisted of a
single topical application (24 h) of the leachate at 100% and 50%
dilution in demineralised water. No visible cutaneous reactions and no
intolerance reaction were recorded in the challenge phase neither at
100% nor at 50%, and no reaction was recorded in the negative
controls.Slag, ferrous metal, blast furnace is not irritating and does
not need to be classified as a skin sensitiser. No signal word and no
hazard statement are required.
There is no indication of any sensitizing
effect of ferrous slag.
There is no skin sensitisation potential of
slags, ferrous metal, blast furnace, as shown in a test according to
