Influence of Sociodemographic Factors on Construction Fieldworkers’ Safety Risk Assessments

Construction operations are hazardous, leading to thousands of accidents, injuries, and fatalities annually. Safety risk assessment (SRA) is a key component necessary to respond to hazards effectively. Individuals have different perceptions of the riskiness of construction hazards, and studies have shown that different sociodemographic factors among employees can alter their SRA skills. However, their role in the US construction industry has been understudied, and this analysis investigates this topic further. Following a detailed systematic review of the relevant literature, quantitative data were collected from 181 construction fieldworkers in the United States using images integrated into an interactive questionnaire survey. Responses on the severity and frequency of seven potential accident causes were captured and analyzed. Findings from the literature review revealed six key sociodemographic factors&mdash:age, education, training, gender, ethnicity, and work type&mdash:that could impact fieldworkers&rsquo: SRA. However, a quantitative analysis suggests that only education is a significant influence, and sociodemographic factors had a statistically significant impact on less than five percent of the assessments. Therefore, the present study proposes that future investigation within the SRA domain should complement sociodemographic factors with critical behavioral factors that are rarely discussed, such as cognitive biases, personality traits, and safety behavior. As a foundational study for safety researchers and practitioners, the results provide information on SRA that can help enhance the safety and workforce sustainability of construction companies with a diverse workforce.
