The Municipal Public Transport microclimate in Chișinău

Abstract

Introduction. At the moment, public transport in Chișinău has a very important role, especially trolleybuses. Every day around 300 units are circulating in Chisinau carrying about 50 thousand passengers. Aim of the study. The problem of the working conditions of drivers and passengers in transport is insufficiently studied. Materials and methods. We measured the microclimate parameters in the trolleybuses from Chișinău with the device Meteoscope M, basic indicators such as air temperature and relative humidity, the current velocity being considered constant 0.1 m / s, according to the norms. Three sets of measurements were performed in order to record the transition from autumn to winter which included 40 electric cars per day, and then the Sigma method was used in order to analyze the statistical average of the measurements The quality index of the microclimate was evaluated, namely the Actual Temperature. Then these results were compared with the regulatory framework in the given domain Results. We compared the results of the Actual Temperature with European regulatory framework nomograms in the field of occupational health and environmental health (89/654/EEC and FRR 2.2.2006-05; RNI 2.2.4.548 -96) and we determined that the actualtemperature exceeded the minimum required in 2 cases. In October the index of actual temperature falls within the normal range, and in December and February it doesn’t reach the normal minimum 18 ° C. Conclusions. This fact speaks about very cold working conditions during the cold season of the year, and as a result one might experience different diseases of the respiratory, urinary or cardiovascular system and many more. It is recommended that the worker wear warm clothing, work breaks, the organization of a special diet.
