Abstract
The construction industry, particularly tunnel construction, exposes workers to respirable crystal line silica (RCS), which can cause incurable illnesses such as silicosis and lung cancer. Despite a range of control measures being implemented, these measures do not completely remove the potential risk of RCS. This research aimed to identify the barriers and challenges hindering the implementation of effective controls and the adoption of safe work practices to protect workers from RCS exposure in tunnelling. A mixed-method approach was employed for this research. Tunnel construction workers were observed, surveyed and interviewed to gauge their knowledge and attitudes and understand their challenges in reducing RCS exposure. The preliminary analysis of the data reveals a diverse array of sociotechnical factors interacting to influence RCS exposure. It is noteworthy that participants consistently emphasised the project as the most exemplary one they have been involved in, although there is room for improvement. Although there is a notable proficiency in understanding RCS exposure and management in tunnelling, there appears to be a noticeable deficiency in perceived contentment regarding dust control. Several factors were identified as interacting to prevent the effective management of dust. These include perceived time pressure, absence of on-tool dust controls for some equipment, and low risk perceptions among workers, and inadequate enforcement of controls. Moreover, participants highlighted communication and heat-related challenges as hindrances to the continuous wearing of respirators. This research highlights the need for a paradigm shift in tunnel construction to address the barriers associated with RCS exposure reduction. It emphasises the importance of collaboration among various stakeholders, advocating for more effective controls, enforcement strategies and enhanced worker education through knowledge sharing.
