The general aim of this work is to analyse environmental vulnerability in the face of possible environmental accidents arising from the transport of dangerous products by road on the BR 101 north, specifically in the region around the Capibaribe river. Based on the assessment of the environmental situation of this stretch, together with the specific objectives of identifying the main products transported on the stretch under study, carrying out a prognosis of the possible environmental damage resulting from possible accidents and observing the vulnerable points of the infrastructure of the stretch under study in the event of a possible accident on the south/north and north/south lanes on the stretch of the BR 101 between KM 64 and 65.3 of the BR 101, delimited by the neighbourhood of Dois Irmãos and the DETRAN community. As for the methodology used, the area where the highway crosses the Capibaribe River was characterised by means of a bibliographical analysis. From now on, the environmental vulnerability is notorious due to the lack of supervision of this type of activity and, above all, the absence of preventive measures aimed at reducing the likelihood of accidents.
