In order to protect the safety of people's lives, rape and property from all kinds of attacks and to maintain the life of people in a peaceful environment, many physical and psychosocial risk elements are encountered when providing security services. Private security officers can face many human-caused disasters such as physical attack, armed attack, social action, bomb attack, terrorist act, knife wounding, sabotage act, industrial accident, transportation accident and work accident while performing their duties. In the event of human-induced disaster, the private security officers themselves, their colleagues and other people they are obliged to protect; in order to keep away from all kinds of physical, chemical, biological and psychosocial risk factors, it is necessary to take some precautions in the context of occupational health and safety. In this study, the level of occupational health and safety awareness of private security officers against human-caused disasters was examined. As a result of the research, while there is no significant difference between the perception of occupational health and safety in private security guards and the variables of gender, education level, position in the institution against man-made disasters; it was determined that there was a significant difference between the age, professional experience and income level variables and the level of consciousness. It has been concluded that there is a positive relationship between the level of occupational health and safety awareness of private security guards against human-induced disasters and  variables of knowing the standardized action styles against disasters, participating in in-service training, proficiency in first aid and dominance of emergency procedures.
