Human reliability assessment for physical security: human responses under extreme threats
Human reliability assessment for physical security: human responses underextreme threats Md Ragib Rownak1, Samuel Abiodun Olatubosun1, Yunfei Zhao1, Carol Smidts1, Abdollah Shafieezadeh2 1Department of Mechanical and Aerospace Engineering, The Ohio State University, Columbus, OH 43210, USA 2Department of Civil, Environmental and Geodetic Engineering, The Ohio State University, Columbus, OH 43210, USA Abstract To further human reliability assessment research for the purpose of physical security, a study on reported human responses during specific real and simulated extreme situations has been conducted. Those responses which are either agitated or depressive in extreme conditions are rarely consistent with responses understood or expected by the public and the media. Rather than responding in irrational and/or self-interested ways under extreme conditions, individuals typically respond in rational and prosocial ways. Though panic behaviors do occur, research suggests this is only when the perception of immediate threats, closing exit routes and a lack of help or resources are imminent. It has been established that typical human behaviors are products of risk identification, assessment and reduction. Almost all human behavior, even in extreme conditions, is based on social norms and the need for attachments. Human factors which affect performance in extreme situations can be categorized as physiological and psychological/cognitive factors. Those factors have been identified and concisely discussed for extreme conditions such as in space/aviation, emergency response operations etc. Those human factors comprise individual, social and situational features such as visibility, fatigue, choice-reaction/response time and working memory/information processing among others. In addition, relationships which exist among few of the factors (extreme temperatures which cause decline in working memory, fatigue which negatively affects vigilance, visual attention etc.) have also been discussed while others which have tendency of dependence need further studies. Moreover, the models of individual behavior under extreme conditions are studied, with the prosocial foundation of human behavior observed. Observations obtained in this study can be used to inform human reliability analysis for physical security scenarios. Keywords: Physical security, human behavior, extreme conditions, human reliability analysis, human performance factors, individual behavior models
