Dangerous substances

Dangerous substances can form a health hazard. They can be inhaled, ingested or absorbed through the skin. Dangerous substances can take the form of liquids, powders or solutions made from the above. Dangerous substances are recognisable by the hazard symbol that appears on the original packaging.

Where are dangerous substances used

A wide range of dangerous substances is used for scientific research at the laboratories of the Faculty of Science (W&N). In other faculties and units, dangerous substances are used in limited quantities, for example for cleaning.

What are the risks posed by dangerous substances

The risks depend on the degree, duration and form of exposure. Laboratories have standard facilities for reducing to a minimum the risks to employees conducting (scientific) research. In addition, efficient prevention measures require appropriate training, instruction and knowledge of the substances in question.

In other faculties and units, the use of dangerous substances is primarily reserved for the cleaning, supporting and technical staff. Examples include cleaning, lubricating, degreasing surfaces, etching, book restoration, etc. These activities only involve a small number of dangerous substances, used in small quantities, so exposure is very low.

Safety data sheets

Suppliers of dangerous substances are required to provide a one-time material safety data sheet (MSDS) to accompany dangerous substances. This data sheet contains among other things information on the (dangerous) characteristics of the substance in question and the preventive measures that have to be taken to work with it safely.

View the MSDS of detergents and other products commonly used within the university which contain dangerous substances.

Finding safety information

You can find the safety data sheets of many substances via Internet. Do keep in mind that the limit values indicated on non-Dutch websites do not always apply in the Netherlands. Every country is free to determine its own limit value for a given chemical substance. For the Dutch legal limit values, please consult the SER website.
