Chromium hexavalent (CrVI) compounds, often called
hexavalent chromium, exist in several forms. Industrial uses of hexavalent
chromium compounds include chromate pigments in dyes, paints, inks, and
plastics; chromates added as anticorrosive agents to paints, primers, and other
surface coatings; and chromic acid electroplated onto metal parts to provide a
decorative or protective coating. Hexavalent chromium can also be formed when
performing "hot work" such as welding on stainless steel or melting chromium
metal. In these situations the chromium is not originally hexavalent, but the
high temperatures involved in the process result in oxidation that converts the
chromium to a hexavalent state.

Preventing Skin Problems from Working with Portland Cement. OSHA, (2008).
Employees may suffer dermal hazards in working with wet cement such as
cement burns (due to its caustic nature) and inflammation of the skin
(either due to irritant or allergic contact dermatitis). This guidance
addresses ways to prevent or minimize skin problems through the proper
selection and use of gloves, boots and other personal protective equipment
such as kneepads; proper skin care and work practices such as use of pH
neutral or slightly acidic soaps; and ways of making cement products less
hazardous.
