The quality of work environment, temperature changes and humidity must be controlled in every production process and in the locations where employees are present. The aim of this paper is to objectively assess the exposure of employees to microclimatic factors of the workplace environment: the warehouse, changing rooms, office and cold room refrigerator. Data were obtained in real working conditions. The heat stress due to cold and heat exposure in the individual locations was evaluated using the WBGT (wet bulb globe temperature) indicator. The parameters of the hygrothermal microclimate (HTM) were objectified by a QUES Temp 44/46 T spherical thermometer. The measurements were performed both in cold and hot periods of the year. The measurements confirmed standard temperatures for individual types of interiors in the winter period, but in the summer period there was a variability of results, leading to the thermal discomfort of employees. The assessment of the WBGT index revealed that nearly 80% of employees are susceptible to hypothermia as a result of thermal stress conditions. It was proven that the temperatures measured by a spherical thermometer in the hottest room were 8.62% higher than the calculated operating temperature, while the difference in the cold room refrigerator was only 1.28% higher.
必须控制每个生产过程中和员工所在场所的工作环境质量、温度变化和湿度。本文的目的是客观评估员工在工作场所环境的微气候因素方面的暴露情况：仓库、更衣室、办公室和冷藏库冰箱。数据是在实际工作条件下获得的。使用 WBGT（湿球黑球温度）指标评估在各个地点因冷热暴露导致的热应激。使用 QUES Temp 44/46 T 球形温度计客观化湿热微气候（HTM）的参数。测量在一年中的寒冷和炎热时期进行。测量结果证实了冬季各个类型室内的标准温度，但在夏季，结果存在变化，导致员工感到不适。WBGT 指数的评估表明，由于热应激条件，近 80%的员工易患体温过低症。事实证明，在最热的房间中用球形温度计测量的温度比计算的工作温度高 8.62%，而在冷藏库冰箱中的温差仅高 1.28%。
