The R phrases and S phrases shall not be used from 1 June 2017.
Hazard classification should be indicated with hazard signs and hazard symbols and/or R phrases as well as S phrases.
R phrase and R number: phrases indicating the risks of hazardous preparations and substances, and their numbers respectively.
S phrase and S number: phrases related to the safe handling of hazardous preparations, and their numbers respectively.
Risk Phrases (R) and Safety Phrases (S) also occur in combinations (combined R and S phrases).
R and S Phrases are separated with dashes or slashes which mean the following:
dash: R Phrases and S Phrases are formulated separately
slash : the possibility of formulating R Phrases or S Phrases in a single sentence (combined R or S Phrases)
It is a general rule that in case of preparations usually a maximum of 6 phrases are applied to inform about the risks; in this respect combined phrases are regarded as single phrases.
The sentences that are applied should inform about all significant hazards of the preparation, therefore in some cases more than 6 R Phrases may be necessary.
The R Phrases on the label as well as the method and aim of the preparation’s intended use should be taken into account in the final choice of S Phrases.
As a general rule, a maximum of 6 sentences are used to inform about the most necessary precautions; in this respect combined phrases are regarded as single phrases.
