During the past five years, physicians, hospital, and clinics have become increasingly interested and involved in providing health care services to workers. Several factors created this increased interest, including hospitals' and physicians' recognition of injured workers as an underserved patient group; labor and management's desire for objective health care provided by independent, nonindustry-employed health care providers; changes in health care reimbursement roles; and increased competition among health care providers. Occupational and Environmental Medicine (OEM) is a specialty in which physicians focus on the evaluation, treatment, and prevention of diseases related to workplace and environmental exposures. They work closely with and advise governmental and state agencies, organizations, and regulatory bodies. Occupational medicine first began in the 1700s, when Bernardino Ramazzini published about the diseases resulting from noxious gas and dust in the workplace and from improper posture of the body. The industrial revolution gave rise to medical inspectors in factories and physicians dedicated to taking care of patients harmed by industry. In 1914, focus on the importance of environmental and occupational exposure lead to the creation of the Office of Industrial Hygiene and Sanitation. An emergency is a situation that poses an immediate risk to health, life, property, or environment.Emergency Department is a medical treatment facility specializing in emergency medicine, that is, acute care of patients who present without prior appointment, either by their own means or by ambulance[1]. Triage is the process of determining the priority of patients’ treatments based on the severity of their condition.
