Construction has been one of the most dangerous industries, with fall being the most common type of hazards. Meanwhile, about one fourth to one third of the industry's taskforce is composed of Hispanic workers, many of whom lack proficiency in English, and/or have limited literacy. Limited literacy and lack of English proficiency are not specific to Hispanic workers and serve as critical barriers in effective safety education and training. The paper presents the developmental efforts and lessons learned of six 3D visualized and scenario-based training case materials that use minimum amount of text descriptions. Common cases that involve construction fall hazards from the National Institute for Occupational Safety and Health (NIOSH) Fatalities Assessment and Control Evaluation (FACE) program were analyzed and modeled in a 3D video game platform referencing the effective training strategies from Occupational Safety and Health Administration (OSHA). Using 3D simulated virtual job sites in safety training is expected to reduce the required level of language proficiency and literacy, and increase the understanding as well as learning interests of those in construction who can't speak or read much English.
