Risk and Safety Statements, also known as R/S statements, R/S numbers, R/S phrases, and R/S sentences, is a system of hazard codes and phrases for labeling dangerous chemicals and compounds. The R/S statement of a compound consists of a risk part (R) and a safety part (S), each followed by a combination of numbers. Each number corresponds to a phrase. The phrase corresponding to the letter/number combination has the same meaning in different languages—see 'languages' in the menu on the left.
In 2015, the risk and safety statements were replaced by hazard statements and precautionary statements in the course of harmonising classification, labelling and packaging of chemicals by introduction of the UN Globally Harmonized System of Classification and Labelling of Chemicals (GHS).
