Applicant's summary and conclusion

Interpretation of results:
practically nontoxic
Remarks:
Migrated information not toxic Criteria used for interpretation of results: EU
Conclusions:
EAF C rat LD50 >2000 mg/kg bw
Executive summary:

To examine the oral toxicity of slags, steelmaking, converter (BOS), a test was performed following OECD guideline 401 in Wistar rats. Fine-ground BOS was dosed at 2 g/kg bw (body weight). After dosing, the animals were observed for a post exposure period of 14 days. The LD50 was > 2000 mg/kg bw.

Slags, steelmaking, converter (BOS) are not toxic via the oral route, and do not need to be classified as oral toxicants. Neither a signal word nor a hazard statement is required.
