Avaliação de riscos ambientais em veículo de emergência utilizado em áreas florestais

Abstract

In the field of forestry work with the possibility of high-severity accidents inherent in forestry operations, emergency vehicles play a fundamental role in maintaining life. Whether working to rescue victims of an accident or transporting patients, they provide support to the health and safety of forest workers. Considering these vehicles as a work environment, the team of professionals who work in them is subject to exposure to various risks. Thus, the present study aimed to assess the environmental risks (physical and ergonomic) of type B emergency vehicles operating in forest areas. The work was carried out in the rural area of Dom Eliseu - PA and consisted primarily of assessing the worker's profile, using an identification form and a short-form Health Survey 36 (SF-36) questionnaire. To assess physical risks, heat levels, ambient light and noise exposure doses were measured. With respect to ergonomic risk, in biomechanics, critical postures and body segments were identified where workers felt greater discomfort during the development of their activities. In anthropometry measurements were taken of the workers' bodies in sitting and standing positions, in the layout of the workstation the internal dimensions of the vehicle were measured. Regarding the profile of the workers, 62.5% were male and 50% were aged between 31 and 40 years old and 75% of the total number of employees had schooling up to high school. The results for quality of life were satisfactory, with adequate physical and functional conditions for the development of the function. They presented acceptable noise levels according to the legislation, even with the use of the siren. However, they have poor lighting conditions, anthropometric inadequacies in the layout; postures potentially harmful to the worker's joints and exposure to heat with maximum of 31.4 ° C, which does not allow the work to be performed without the adoption of control measures
