The widespread use of operator labor in modern automated and mechanized production dictates the need to optimize the working environment in order to preserve their health and improve their efficiency.

Operators of control panels are often forced to work at an air temperature close to the temperature of the human body surface, or slightly exceeding this limit, which causes a significant tension in thermoregulation, cardiovascular system, changes in water-salt metabolism, a sharp decrease in working capacity [2, 4, 5] ... At the same time, when the microclimate is normalized, labor productivity increases sharply - up to 10% [6], and the price of rolling metal decreases by 0.6% for each degree of air temperature decrease at the operator's workplace to the optimum value.

Conclusions: the optimum air temperature when performing intense operator work (III category of tension) is 17-19 ° C with thermal irradiation up to 350 W / m2, relative humidity 40-60% and air velocity 0.1-0.2 m / from. Permissible levels of air temperature are 15-24 ° C at a relative humidity of 40-75% and an air velocity of 0.2-0.5 m / s.
