Risk and Safety Statements
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.
