Indor Air Quality in an auto repair shop-case study

Andrzej Gajewski , Kacper Jermacz


The aim of the paper is indoor air quality (IAQ) assessment in an auto repair shop due to CO2 and CO concentrations. Carbon monoxide and carbon dioxide concentration were being measured for a week. Two Testo 435-4 gauges were located at height of a head of an adult person (ca 170 cm above floor) in a room. CO2 concentration was measured with IAQ probe which measures dew point temperature, psychrometer temperature and absolute pressure in indoor air. The second gauge was connected to CO probe. Measurements were done every 5 minutes and were averaged in an hour. Uncertainties were estimated using square-root combinations of fixed errors and random ones at 0.05 statistical significance. The measurements were done from 17th November to 23rd November 2018. The following graphs are plotted for carbon dioxide and carbon monoxide: hourly averaged concentration and 8-hour averaged concentration. The results are discussed and compared to Polish, foreign and international standards or recommendations. There were observed negligence of Polish law and nonfulfillment of healthy recommendations. An exhaust extraction system should be installed.
