Measurements in the manufacturing plant are showing very high temperatures
during summer, but the situation is only a little better during the rest of the
year. In the analysed period, the temperatures outside vary from 6 to almost
30°C, but the temperatures at the workplace never fall below 22°C and rise up
to 33°C (Figure 2). WBGT values are mainly between 20 and 25°C, which is al-
ready high for moderate or heavy work, as heat stress management have to start
around WBGT value of 25°C for heavy work (Gao et al., 2017).
Workers in this manufacturing plant are reporting thermal discom-
fort, especially if they need to wear specific clothes like thick black polo shirts,
which are not a part of protective clothing. The effectiveness of our autonomic
heat dissipation capacity is related to what type of clothing is worn and the en-
vironmental conditions (Lucas et al., 2014).
Figure 2: Working conditions in the manufacturing plant near Celje:
measured air temperature at one workplace at 1.5 m height (T workplace),
calculated WBGT index (WBGT workplace) and measured air
temperature at meteorological station Celje (T outside).
In the manufacturing plant, the cooling system is not efficient enough
due to injection molding machines as additional heat sources. For 20% of work-
ers working conditions during heat waves are perceived as hot, for another 20%
too hot, and for 45% extremely too hot (Figure 3). Tourist guides did not an-
swer that question as they do not have a permanent workplace. Conditions are
certainly better in offices, as 66% workers have air conditioning at their work-
place and 11% in the vicinity. However, more than half of them did rate work-
ing conditions during heat waves as hot (or worse), and only for 20% workers
is the temperature suitable, so air conditioning does not solve the problem as
a whole. For 27% of agricultural workers is working outside during heat waves
extremely too hot and for 36% too hot. There were no significant variations be-
