Floods are one of the major natural disasters that contribute to the high disaster death rate in the global south, especially in Nigeria. This requires an effort of collaboration from all stakeholders in designing, building, deploying, and maintaining inclusive disaster management systems. This effort can hardly be achieved without the application of universal design principles in designing rescue applications. In this research, we have studied situational disabilities and their effect on situational awareness based on the data collected from victims in Nigeria through a questionnaire with 56 respondents and 5 follow-up interviews. The research work contributed to identifying situational disabilities and their corresponding accessibility barriers based on difficulty experiences collected from the research participants in Nigeria.
