Ergonomic Evaluation of Automotive Training Workshops in Commercial Premises within TVET Institutions

Abstract

This study evaluates the suitability of a modified commercial premise used as an automotive training workshop in a TVET institution from the perspective of environmental ergonomics. A quantitative approach was employed using environmental observation and a questionnaire administered to 54 students. Data were collected across seven workshop zones, focusing on temperature, humidity, air flow, lighting, and noise levels. The findings indicate that thermal comfort factors did not comply with ASHRAE 55 standards, lighting in several zones was below the minimum requirement, and noise levels exceeded 70 dB in most areas. Student perceptions also recorded moderate mean scores for comfort and safety, with the questionnaire reliability measured at Cronbach’s Alpha of 0.897. The limitations of this study include the use of a single commercial premise, a limited sample size, and the measurement of only selected ergonomic parameters. The study recommends improvements in ventilation, artificial lighting, and workspace layout to ensure that alternative workshop spaces provide a safe and conducive environment for TVET practical training.
