[Exposure to benzene in gas stations in Brazil: occupational health surveillance (VISAT) network]. / Exposição ao benzeno em postos de revenda de combustíveis no Brasil: rede de Vigilância em Saúde do Trabalhador (VISAT).

The scope of this article is to present the surveillance network's experience of exposure to benzene in gas stations, describing its components developed in the Unified Health System. It is a report and analysis of the experience of monitoring and its impact on the health of gas station workers in six Brazilian states. It presents the prospect of action, operated by the circulation of information, national meetings, discussions of specific strategies and shared experiences, methodologies and common tools. Inspection procedures, individual assessments and training are described. Risk situations and occupational and environmental exposure were identified in 1,311 gas stations and 564 workers were assessed. Forecourt attendants, superintendents and measuring, offloading and testing employees were all exposed. The integrated and complementary features of this surveillance, implemented in the occupational and environmental areas, suggest intervention in a broader and network-linked territory. The intervention would transcend fragmentation between individual and collective practices, services and education, becoming an example of action for assessment and mitigation of the impact on health workers, the articulation of action in health, the environment and intersectorial connection.

[Surveillance experience in the sugarcane sector: challenges in disrupting the perilous "marathon" of the sugarcane plantations]. / Experiência de vigilância no setor canavieiro: desafios para interromper a "maratona" perigosa dos canaviais.

The sugar-alcohol sector is growing year by year, especially in the state of Sao Paulo where approximately 42.9% of the sugar-ethanol plants are concentrated. The production chain is a subject for concern to public agencies and to civil society by exposing migrant workers to risks arising from the work process. In Sao Paulo, from 2006-2009, Occupational Health Surveillance (VISAT) set up two initiatives to address problems related to the housing and working conditions of sugarcane workers. The objective of this article presented in the form of an essay is to analyze the experiences in their context. The methodology used combines document analysis with the perception of the authors who participated in the actions. The experience led to improvements in these conditions and fostered public debate on the conditions of such physically demanding work. The interventions resulted in a definition of sanitary norms and initiatives at the legislative and judicial level, but even the most successful measures failed to attain the organizational targets, especially a production remuneration structure that challenges the traditional action of surveillance and the impacts were weakened due to the fragility of worker representation for the sector.
