The improper use of chemicals can lead to accidents. It is therefore important to read the information on chemical packaging labels carefully, to know what the hazard symbols mean and to use the product in accordance with the information provided.
Hazard symbols overview
While not all hazardous substances are accompanied by the correct pictogram and the packaging sometimes does not feature any pictogram at all, this is no guarantee that the substance in question is safe.
Some very dangerous (carcinogenic) substances are not packaged, but are instead released while work is carried out, for example diesel and welding fumes or wood dust.
Some symbols may appear together on the same product. Please click the following link for the overview of hazard symbols (Dutch) on the website nvwa.nl.
