Chromium Wikipedia

Chromium is a member of group 6, of the transition metals. Chromium(0) has an electron configuration of [Ar]3d 5 4s 1, owing to the lower energy of the high spin configuration. Chromium exhibits a wide range of oxidation states, but chromium being ionized into a cation with a positive 3 charge serves as chromium's most stable ionic state.

Hexavalent chromium Wikipedia

Hexavalent chromium (chromium(VI), Cr(VI), chromium 6) is any chemical compound that contains the element chromium in the +6 oxidation state (thus hexavalent).Virtually all chromium ore is processed via hexavalent chromium, specifically the salt sodium dichromate.Approximately 136,000 tonnes (300,000,000 lb) of hexavalent chromium were produced in 1985.

HEXAVALENT CHROMIUM EMPLOYEE TRAINING INTRODUCTION

• When dealing with chromium 6, proper housekeeping is critical to minimize exposure. • Chromium 6 that settles on ledges, equipment, floors and other surfaces should be removed as soon as possible to prevent it from becoming airborne and to minimize the risk of skin contact.
