1. What human factors issues did you identify in the case study? The first human factors problem I identify is the electric pilot light sparking. This is the cause of the fire and so is certainly a design issue from a human factor perspective. Next comes the design of installing steel security bars at each window. Although the design of steel security bars is intended to protect the residents of the home, it has a fatal drawback that limits the escape action of the residents. The case study proposed a solution: anti-panic equipment. However, the home only installed one set of panic hardware, indicating another human factor issue that arose when setting up the home's security system. Additionally, the one and only set of panic equipment in the house had to be stomped harder to activate. This reflects poor design of panic hardware due to human factors. Another human factors problem I identify in the case study is poor communication between the 911 operator and the fire dispatcher, as well as between the fire dispatcher and the nearby fire station. Although the operator specified the address as number 9 to the dispatcher, the 911 operator missed the word "avenue" in the address when informing the fire department dispatcher of the location of the fire. Additionally, due to a communication problem between them, the rescue operations were delayed for more than four minutes. To make the situation worse, the dispatcher sent the wrong address, 3100 blocks of 9th Street, in his order to the nearby fire station for a rescue action, which should be 3102 blocks of 9th Avenue. In addition to the above problems, as shown in the case study, similar problems ...... middle of paper ...... can prevent the occurrence of an accident. Additionally, the pressure required to activate all panic equipment is not appropriate for the emergency situation or the user. Its activation should be easier and faster because it is designed for emergency evacuation plans. Finally, the city should make efforts to differentiate street names to avoid any misunderstanding or misinterpretation of the address which would lead to latent failures. and responsible for security.
