Gentlemen:
We are currently dealing in 75% ferrosilicon, ferro silicon chrome and ferro silicon calcium. We
have had the material tested in accordance with DOT Standard 173, Appendix E, Division 4.3
(dangerous when wet material) and are enclosing the results herewith.
It is our understanding that the enclosed results show that the 75% ferrosilicon, ferro silicon
chrome and ferro silicon calcium would not fall into the category of Hazardous Material and
therefore does not require special handling or marking.
We would appreciate it if you would confirm that you agree with the above. If you have any
questions, please let us know. Thank you in advance for your help in this matter.
Sincerely yours,
Considar, Inc.
