The Globally Harmonised System of Classification and Labelling of Chemicals (GHS) is a system for chemical hazard communication.
 
GHS Labels are used to minimize or prevent adverse effects caused by exposure to hazardous products.
 
This pictogram is put on a chemical label when a substance presents these health hazards:
Carcinogen–may cause cancer
Respiratory sensitizer–may cause respiratory irritation
Reproductive toxicity–may damage fertility or the unborn child
Target organ toxicity–may cause damage to bodily organs
Mutagenicity–may cause genetic defects
Aspiration toxicity–may be fatal if swallowed and it enters the airways
