Standard Guide for Safety and Health Requirements Relating to Occupational Exposure to Water-Insoluble Chromates
The following bibliographic material is provided to assist you with your purchasing decision:
Scope
1.1 This guide covers control procedures for the safe production, storage, transportation, and handling of only the hexavalent chromium compounds found in and their various hydrates, and mixtures of coprecipitates of the same regardless of crystalline form.
1.2 This guide is not intended to cover ( a) such "soluble" chromates as chromates of sodium, potassium, magnesium, or ammonium; (b) soluble bichromates; (c) chromic acid; (d) volatile chromyl compounds; (e) any trivalent chromium compound; or (f) elemental chromium. Omission of said compounds or classes of compounds should not be construed to mean that they may be handled without due regard to their particular physical, chemical, and toxicological hazards
1.3 The chromate ion, CrO
This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of whoever uses this standard to consult and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
Significance and Use
This guide includes chromates that are not readily soluble in water and that have water solubilities (Chromate ION) within the range of the more soluble calcium chromate and the much less soluble lead chromate. The major occupations involving potential exposure to insoluble chromates are in roasting of chromite ore, the manufacture of chromate pigments, the manufacture of coatings containing chromate pigments, and spray painting with these coatings. There is insufficient evidence to conclude that trivalent chromium compounds are carcinogenic.
