Due to the changes in the contemporary labor world and their repercussions on health and environment, new challenges are posed to Worker's health Integrated Care from the Brazilian National Unified Health System. Aiming at analyzing the experiences in this field, we examined the Surveillance Project carried out in Gas Stations by the Worker's Health Reference Center of Campinas, São Paulo. Based on interviews with health workers and other actors involved, we reconstructed its trajectory estimating its potentialities and difficulties. We observed that the collective construction of actions and the preparation of the agents to conduct surveillance in gas stations joined professionals from different institutions, with distinct backgrounds and expertise. In the interviewees' opinion, the process improved the involved agents' view concerning exposure to chemical risk, and gathered efforts which resulted in improving working conditions, and enlarging social control, besides regulating the gas production, distribution and consumption. They mentioned difficulties related to group work added to overload of work. We concluded that establishing priorities aimed at developing intra and inter-sector networks is strategic to change working processes in such a way that it benefits health and environment.
