AB - This study investigates the validity of alarm concentration and response time criteria for gas detectors in preventing chemical leakage accidents. Various leakage scenarios were simulated to compare detection times under different sensor sensitivities and response speeds. The analysis revealed that when the detector’s response time was delayed from 6 to 12 seconds, the hazardous distance for human exposure and explosion risk expanded by approximately 10–25 meters. This demonstrates that delayed detection significantly reduces the time available for emergency response, increasing the likelihood of secondary damage. Conversely, when the response speed was improved to 6 seconds or less and coupled with automatic shut-off valves and ventilation systems, the gas dispersion range decreased by more than 20–30% on average. These findings indicate that enhancing detector response speed plays a crucial role in improving the reliability of early-warning systems and substantially contributes to accident prevention by minimizing both the affected area and potential casualties. Therefore, technical measures to improve response speed should be prioritized as an essential strategy for strengthening on-site safety management.
