Focuses on three populations that research indicates are at increased risk for adverse work-related health outcomes—Hispanic immigrants (individuals born in Latin America who currently live in the United States), small business employees (firms with fewer than 20 employees), and young workers (25 years old)—with a specific focus on implications for the construction industry. It explores how the combination of risk factors may result in overlapping vulnerabilities for workers such as young immigrants in small construction firms and discusses the implications for safety professionals.
