Schools have to ensure student safety and well-being. However, medical emergencies involving injuries are common, requiring teachers to provide prompt first aid before professional care arrives. This study assessed knowledge and awareness of first aid among school teachers to identify areas needing improvement. This cross-sectional study surveyed 371 teachers from the eastern region primary schools using a standardized questionnaire assessing first aid knowledge across areas like bleeding control, fractures, seizures, choking, and burns. Demographic factors were analyzed for correlations with knowledge levels. Pearson's Chi-square tests analyzed bivariate relationships comparing correct knowledge identification percentages across teacher sociodemographic. The level of statistical significance was at a P value <0.05 across tests. Only 157 teachers felt able to appropriately handle medical emergencies. Major knowledge gaps existed regarding airway obstruction and chemical injuries, with 168 unable to identify correct responses for choking first aid and 105 unsure of chemical burn management steps. Appropriate fracture management was lacking, with just 70 correctly endorsing nose pinch for nosebleeds. Cardiopulmonary resuscitation knowledge was inadequate, with 57 of teachers unaware of the basics. Teachers demonstrating higher knowledge levels overwhelmingly had prior first aid training (153, 66.5%) compared to untrained counterparts (89, 63.1%). The study revealed poor first aid knowledge among elementary school teachers for effectively managing child emergencies. Strategies enhancing delivery must address barriers around training access, knowledge attrition, and variability in baseline skills through sustainable system-wide policies applied nationally. Fulfilling schools' ethical obligations toward maintaining student safety requires urgent reforms to bolster emergency preparedness.
