In a survey conducted on a polytechnic in Malaysia, many of the students and lecturers expressed feeling of discomfort and uneasy due to resulting smoke from the welding activities while attending the workshop session. They felt that the room temperature and humidity also contributed to discomfort. Consequently, students had difficulties to concentrate and focus on their learning. The objective of this study was to determine the indoor air quality of a selected welding laboratory in the polytechnic comprising arc and gas welding stations. The important IAQ parameters considered in this study were the dry bulb air temperature, relative humidity, CO2 level and dust particles. Measurements were conducted using commercial IAQ instruments. From the study it was found that the levels of dust particles was higher than the recommended limit at times in the arc welding station. The CO2 level was observed acceptable in both welding stations. On relative humidity, a mixed result was found. Overall, the results implied that the welding laboratory require attention in meeting acceptable Indoor Air Quality. © (2013) Trans Tech Publications, Switzerland. date: 2013 official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-84886308620&doi=10.4028%2fwww.scientific.net%2fAMM.393.947&partnerID=40&md5=9ce7be3e55dc02dafdc1dbdc4cdedc6a id_number: 10.4028/www.scientific.net/AMM.393.947 full_text_status: none publication: Applied Mechanics and Materials volume: 393 place_of_pub: Malacca pagerange: 947-952 refereed: TRUE isbn: 9783037858233 issn: 16609336 citation: Azmarini, A.N. and Majid, S.A. and Zakaria, S.H. and Sulaiman, S.A.
