Signal word
When transporting hazardous goods, other information in addition to the GHS symbols must be noted on the packaging and on the transport vehicle. This helps to be able to take the right measures in the event of damage and to enable conclusions to be drawn about the hazard category.
H-phrases
H-phrases and P-phrases can also be assigned to the individual GHS symbols. In the EU, EUH phrases are also used. They give concise safety instructions for hazardous substances and have an analogous use as, for example, the R- and S-phrases; which can be found in the EU labeling.
P phrases
The P-phrases work according to the same principle, where “P” stands for “Precautionary Statemens” and refers to safety instructions when handling the respective hazardous substances:
