I. Introduction
HAZWOPER emergency response work represents one of the most dangerous jobs in the United States (U.S.) where, in many cases, emergency medical first responders are expected to deliver immediate care to persons suffering from acute traumatic injuries and exposure to hazardous substances (e.g., chemical spills). Therefore, the HAZWOPER standard devotes very specific and detailed attention to training that represents a major departure from classical emergency medical first responder action. Although advanced training technologies have emerged over the past decade ranging from mobile to virtual reality head mounted displays (HMD)s, current HAZWOPER training technologies are insufficient at tutoring, debriefing, and quantifiably, evaluating fire-fighter hands-on skill proficiency while, simultaneously, allowing both hands free to practice emergency clinical skills. The National Institute of Environmental Health Sciences (NIEHS) and Occupational Safety and Health Administration (OSHA) in the United States (U.S.) require realistic HAZWOPER (Hazardous Waste Operations and Emergency Response) training that measurably develops hands-on skill proficiency.
