ABSTRACT
The article presents outcomes of environmental parameters studies made on scaffoldings. For this purpose, air temperature and relative humidity were used. Unfavorable environmental conditions can affect the behavior of people working on scaffoldings, resulting among others in tiredness and reduced reaction time. This increases the risk of dangerous situations occurrence. Therefore it is important to show what kind of climate changes the worker is exposed to. Outcomes are presented for three scaffoldings located in Lodz, Warsaw and Wroclaw. Air temperature and relative humidity varied depending on both the time of the day and the height of the working level on which the measurements were made. Air temperature in most cases was increasing, while the humidity was decreasing. Analysis have shown that users are exposed to highly variable climatic conditions, which are difficult to adapt in the short term, and heat discomfort caused primarily by high temperatures.
