REGIMES OF WORK OF CAR ASSEMBLY CONVEYOR IN CONDITIONS OF HEATING UP MICROCLIMATE

Abstract

In the car assembly conveyor workplaces in summertime, high air temperature up to 30-31°С is observed. The purpose of the present research was establishment of parameters of a regime of work - physiological intensity of the working process (an integrated estimation of density and rate of labor actions), time and conditions of rest protecting workers from sharp exhaustion and overheat. There has been described the method of definition of a level of physiological intensity of physical work in which the risk of thermal overheat and sharp exhaustion of workers in conditions of a heating up microclimate was prevented. Use of the method is shown in terms of development of physiologically safe regimes of work in the car assembly conveyor by air temperature in workplaces 26-31°С. There have been determined variants of admissible combinations of parameters of operating modes (physiological intensity of work; conveyor productivity; total time of regulated breaks in work) and conditions of rest (decreased air temperature in rest points; speed of air movement at rest; a share of time of rest in a sitting position). Admissible physiological intensity of work and productivity in the car assembly conveyor workplaces has been established by air temperature 26-31°С and relative humidity 40-50%.
