摘要：The article presents the results of research on hazards induced by thermal conditions illustrated by the example of air temperature. Presented results concern ten construction scaffoldings located in Wroclaw, which were investigated from May 30 to October 14, 2016. The scaffolding area ranged from 146 m2to 1303 m2. On three scaffoldings, the air temperature was above 40 ̊C. The air temperature in 46 % of cases was in the unfavorable for employees temperature range. In addition, people working on scaffoldings are exposed in most cases to strong or severe thermal stimuli connected with large temperature differences during the working day. Unfavorable, dynamically changing climatic conditions pose a serious threat to people working outside. There is an increase in errors, and as a result the risk of situations that could lead to an accident increases.
