This research investigates the impact of communication and language barriers on migrant workers in the Singaporean construction industry, focusing on how these barriers contribute to accidents. It identifies less knowledge of English, cultural diversity, and status differences as key factors hindering effective communication and comprehension of safety guidelines. The study uses both quantitative and qualitative data, including surveys and case studies, to analyze the relationship between communication barriers and safety incidents. The findings suggest that implementing effective training programs for language and safety, along with establishing employee feedback mechanisms, can significantly reduce accidents. The research concludes by recommending strategies to overcome these barriers and improve safety outcomes for migrant workers in the construction sector.
