Approximately 67 million tonnes of dangerous goods are transported on inland waterways every year. More than 80% of dangerous goods not carried by pipelines are transported by water, the majority of which are combustible fluids, which are almost always transported in tankers. The remaining goods are chemicals and waste materials.

Tasks of the Human Environment and Transport Inspectorate
The Human Environment and Transport Inspectorate oversees the safe transport of dangerous goods on inland waterways. The Inspectorate monitors harbours to see whether dangerous goods are being loaded and unloaded in accordance with regulations. The Inspectorate works closely with the National Police Services Agency (KLPD), the waterways police and the Directorate-General for Public Works and Water Management.
