All substances, mixtures and products whose physical-chemical, chemical or toxic characteristics may endanger the health and safety of employees are also considered hazardous substances.

There is also a generalized definition for environmental hazards, according to which substances or mixtures are dangerous for the environment and thus hazardous substances, in that the “themselves or their transformation products are otherwise suitable for changing the nature of the natural balance, of water, soil or air, climate, animals, plants or microorganisms in such a way that dangers to the environment can be caused immediately or later”.
