High-risk combinations of hazardous substances

Some hazardous substances can react with each other, causing dangerous gases, vapors or other dangerous situations. 

Substances that can react dangerously with each other must be stored separately in drip trays. These can be plastic drip trays of at least 110% of the contents of the largest package or bottle. 

The rule of thumb is that only substances of the same type should be stored together, unless section 7.2 or 10 of the SDS states that this is not a problem. 

Substances without a hazard label can be stored together without restrictions. 

Good practice: on the CAMEO Chemicals  website you can easily see whether two or more chemicals react with each other in a dangerous way.
