For a number of variables, market prices are available or can be derived. For human health andwell-being, however, there is no market value. In practice, the monetary value is sometimes
constructed by asking people of their willingness to pay to avoid injuries. The results of these
methods, however, are often criticised.
In general, it is best to express as much as possible in terms of money. If that is not possible ornot wanted, try to quantify or use ranking methods. This can also help in decision-making and
can show improvement in safety and health management.
