The first step in the model is for employers to define what constitutes workplace violence. The U.S. Department of Labor defines workplace violence as homicides, suicides, and assaults that occur while individuals are employed. The model recognizes that internal and external environmental factors have varying degrees of influence on workplace violence. Assessing the internal environment should include a review of workplace hazards, while assessing the external environment should include a review of Federal, State, and local laws requiring employers to protect employees from workplace violence. After the environmental assessment is completed, occupational and industry risks faced by employees in their daily job tasks should be evaluated. This occupational risk assessment will be helpful in developing workplace violence prevention policies that protect employees. Security procedures to be implemented depend on information obtained from the environmental assessment and the occupational risk assessment. Other components of the model include applicant background investigations, centralized entrances and exits for employees, centralized visitor clearance, dispute resolution procedures, employee assistance, violence prevention training, well-lighted work areas, security systems, and employee identification badges. 22 references, 4 tables, and 1 figure
