According to a survey, the French take three types of action in fire protection: fire prevention education for the public (for example: the communities have to manage their domestic waste dumps in a way that prevents spontaneous combustion), surveillance of forested areas for early fire detection and vegetation management to reduce fuels. The danger of fire in the forest areas seems to be a real problem for inhabitants of south-eastern France. That is the reason why the authorities released a plan of risk zones ("Plan de Zones U Risque"). The document from 1992 classified the territory in fire risk zones and provided a method of preventing their outbreak and spreading.
