This thesis is about how Umea Municipality is working with environmental sensitivity maps. Surveys have been sent to the environmental office, fire department and Lantmäteriet. A literature study has been done in order to found out why it’s important for the fire department to take into account the environment. The starting point for this study has been the environmental sensitivity map that was made for the municipality of Umea in 1998 for accidents where firefighting water and chemicals are involved. Fires can cause many environmental problems. A substance that can spread in the environment when a fire happens is cadmium which can make it difficult for animals to absorb nutrients in the food they eat. The firewater can contain many substances that are harmful to the environment for ex. volatile organic compounds (VOC). A groundwater map from the geological survey of Sweden (SGU) and Swedish Civil Contingencies Agency (MSB) for the fire department in Umea municipality was made in 2007. The groundwater map is used in the fire trucks in a GPS system. They can see directly on the GPS a map for the area where the accident has happened. It’s used when there is a chemical leaking for example from a truck that has gone off the road. The map that shows environmental sensitive areas is used by the fire department in Umea municipality and the environmental office. Firefighters have to call the fire station or the environmental office to get information from the map. The bad thing is that the map for environmentally sensitive areas is not updated.
