Personal threats to safety not only threaten emergency medical staff, but are also likely to delay rescue of other acutely and critically ill patients. Although the Department of healthcan issue guidelines for emergency situations, it cannot actually effectively end violence in the emergency department (ED). This article references hospitals in Hong Kong, Japan, and Canada and suggests that the government consider ED violence an offense against public safety. The current policy of not arresting those who commit violent acts in the ED should be changed, and perpetrators should be charged with an indictable crime to achieve a deterrent effect. In addition to upgrading, hospitals must also step up teaching and training of security personnel to deal with these situations, and set up an experienced crisis management group to create a safe environment. There should be a ”zero violence, risk-free” goal to provide emergency personnel a safe working environment.
