Incompatible chemicals

The use and storage of incompatible chemicals requires particular care.

Main content

A number of chemicals react very dangerously with each other when mixed together. It is essential to be aware of these chemicals at all times when it comes to the use, transport, storage and waste handling of chemicals.

Special attention should be paid to these chemicals and groups of compounds during use or storage in order to avoid accidents and injury or damage to people, materials and the environment. To help with identification, a table of incompatible compounds has been drawn up, together with a matrix showing groups of incompatible chemicals. (These lists are not exhaustive.)
