Emergency Responders Contain Toxic Acid Leak At Jiangsu Plant After Pipeline Failure Injures Four

Nanjing, China—Industrial emergency response crews and municipal hazmat units sealed off a high-capacity chemical processing park in Jiangsu Province on Wednesday afternoon after a high-pressure line failure sprayed toxic acidic compounds, leaving four workers hospitalized.

The pipeline rupture occurred around 2:20 p.m. inside a secondary refining workshop during routine maintenance operations along an elevated transport manifold. A high-pressure seal degraded rapidly, discharging concentrated acidic fluids and high-temperature steam across the surrounding catwalk.

Four technicians stationed on the maintenance platform sustained direct contact with the corrosive liquid before automated pressure isolation valves closed the main supply feed. Facility supervisors initiated emergency evacuation protocols across the workshop bay while internal safety crews deployed water curtains to dilute airborne vapor clouds.

Emergency medical teams and specialized trauma ambulances dispatched to the industrial zone treated the four injured workers at the facility perimeter. Paramedics stabilized the victims—suffering from varying degrees of chemical skin burns and inhalation trauma—before transferring them under police escort to a specialized hospital in Nanjing.

Regional fire rescue services deployed specialized decontamination units to neutralize liquid pools on the workshop floor and prevent corrosive runoff from entering industrial drainage networks. Hazmat technicians equipped with self-contained breathing apparatus monitored local ambient air quality to ensure hazardous gases did not drift into neighboring residential quarters.

Inspectors from the provincial Emergency Management Bureau arrived on site before 4:00 p.m. to issue a formal suspension order for the affected refining line and launch an immediate technical review. Field engineers are examining material fatigue, valve pressure logs, and recent maintenance records to isolate the root cause of the joint failure.

Local environmental protection officers set up monitoring posts along the perimeter canal system to confirm zero toxic seepage breached secondary retention dikes. Representatives from the operating company stated that full medical support is being provided to the injured personnel while internal safety audits proceed.

Provincial safety inspectors maintained active containment barriers around the workshop sector into Wednesday evening while technical teams completed final pipeline purging operations.
