Emergency shutdown systems are safety mechanisms designed to quickly halt operations in industrial processes or machinery during dangerous situations. These systems help prevent accidents, protect equipment, and ensure the safety of personnel by automatically or manually stopping operations when specific conditions are met. Typically, emergency shutdown systems include sensors, alarms, and control panels that monitor various parameters like pressure, temperature, and flow. When abnormal conditions are detected, the system activates to isolate equipment or shut down processes, minimizing risks associated with hazardous materials or explosive environments.
