Many consider that decision-making based on science is the only objective way to set policy in a world of diverse opinions, values and interests. Hazards, and the chance of those hazards occurring, are thereby studied and models constructed to predict the risk. The two components of risk both contain a measure of uncertainty, and it is this measure of uncertainty that is the focus of many discussions. In particular, the hazard component of risk analysis is subject to close scrutiny. Risk management and alternatives analysis Risk management ,5 distinct from risk assessment, is the process of weighing policy alternatives in consultation with all interested parties, considering risk assessment and other factors relevant for the protection of consumers' health and for the promotion of fair trade practices as well as, if necessary, selecting appropriate prevention and control options.
Environmental hazard is probably less easy to quantify than health hazard.
In both instances, only long-term experience can show if risk assessment and risk management have been successful. When a sound risk management strategy is applied to environmental problems, as distinct from safety problems, it will begin by describing a problem and the goals, objectives and values to be pursued by solving that problem. An analysis of alternatives is then carried out to consider as many solutions as possible. Rather than narrowing the analysis, this allows the creation of new options or combinations of options. When the benefits and drawbacks of a wider range of solution scenarios can be compared, fuller participation by the concerned society can be better assured.
