Situations of serious and imminent danger: proposal of a methodology for prepar...
Cipriano Almeida; Rui Cruz; Miguel Tato Diogo; João Santos BaptistaCamping parks are work, recreational and leisure locations of high risk when facing situations of serious and imminent danger, especially during peak season, not only due to higher climatic temperatures but also due to an increase in visitors, motorized vehicles and diverse materials and equipment. During this season a large number of undifferentiated personnel have to be contracted and employed in order to dea...
Occupational Exposure to Dust in Open Pit Mining. A Short Review.
Maria Matos; João Santos Baptista; Miguel Tato DiogoA literature review concerning the scientific knowledge of all the key factors related to respirable crystalline silica dust exposure was conducted and a chronological evolution of the state-of-the-art knowledge that can respond to questions raised by the development of the work done in quarries and opencast mines is presented, based on bibliographic research. Findings assert that exposure to silica dust is the...
Effects of thermal environment on cognitive response in sedentary activities. A...
Emília Quelhas Da Costa; João Santos Baptista; Miguel Tato DiogoThe study about the influence of the thermal environment on cognitive response is fundamental to understanding better the connection between the basic variables and cognitive performance. This also helps the better understanding of safety situation, guidance and decision-making, especially to avoid critical situations. The main objective of this work is to relate the physiological with cognitive response, tryin...
