Hazardous substances are substances or mixtures that could endanger the health and safety of employees. A distinction is drawn between:

  • acutely dangerous such as flammable and explosive substances but also intoxicating and suffocating substances;
  • dangerous over a prolonged period such as irritating substances, substances that can cause allergies, substances that can damage the airways or the nervous system, cancerous substances, reprotoxic substances and mutagenic substances.

You can recognise the hazardous nature of a substance from the hazard symbols on the package labelling and the list of Hazard and precaution sentences.
