Abstract: As is well known, the production and use of hazardous chemicals plays a vital role in socio-economic development. However, it should also be recognized that incidents such as leakages and explosions can occur during storage, transportation, usage, and other stages due to inadequate management or unforeseen incidents, posing threats to public safety and property. This paper investigates the current status of emergency monitoring when hazardous chemical leakage occurs. Concurrently, it explores the standardized emergency monitoring in order to better serve the response and disposal of emergency environmental emergencies caused by hazardous chemical leakages.

Key words: hazardous chemical, leakage, emergency monitoring, standardization, environmental emergency
