What is GHS?

Although most developed countries around the world have already adopted self-regulatory systems for classifying and labeling flammable and hazardous materials, a universal system is required for maximum safety.   Like the United States' MSDS program, many of these systems are similar to other country’s programs, but the inherent cultural and linguistic differences are often great enough to warrant multiple documentations (safety data sheets, labels, etc.) when these products need to be transported internationally. This can, at best, lead to confusion and, at worst, cause tragedy.

Though not sanctioned or prosecutable by any international laws, this standard has a backing by the EU and the United States.
