Lynn L. Bergeson, “Aligning Chemicals Labeling with Global Rules Involves Major Efforts,” Chemical Processing, March 2010.

GHS provides harmonized criteria for classifying chemicals according to their health and physical hazards, and specifies hazard communication elements for labeling and creating safety data sheets (SDS).
