This paper focuses on the analysis and interpretation of primary research that was conducted on the topic of critical incident stress management (CISM) and post critical incident stress debriefing (CISD) protocol for first responders. Examined in this paper are sources of research from scholarly reviewed journals, legitimate on-line sources, and periodicals that focus on the subject of critical incident stress management and debriefing for first responders. The analysis of the primary research that is illustrated in this paper includes research on different practices around the world and also identifies the need for critical incident stress management and debriefing, potential hazards, and consequences of lack of implementation of post critical incident stress management and debriefing protocols for first responders. The variables are the role of emergency preparedness training, real-time stress management, and critical incident stress debriefing. The research will focus on 3 countries; the United States of America, England, and Israel and the correlation between effective pre and post critical incident protocol implementation and the reduction of the psychological effects that first responders may experience if they are not properly debriefed.
