A major industrial accident occurred at a pharmaceutical manufacturing facility in Sri City Special Economic Zone (SEZ), Tirupati district, Andhra Pradesh, when a boiler exploded on the morning of 3 October 2026.
The powerful explosion triggered a fire and caused part of the facility to collapse. Five workers lost their lives and around 10 others sustained serious injuries. Emergency, fire and rescue teams rushed to the facility and shifted the injured workers to hospitals for treatment.
Incident Details
The incident took place at a pharmaceutical manufacturing facility in Sri City, an industrial zone housing more than 250 companies.
According to reports, the explosion occurred during a shift-change period. The force of the blast caused significant damage to part of the building, with some workers reportedly becoming trapped beneath the collapsed structure.
Firefighters, police personnel and rescue teams immediately responded to the emergency. The resulting fire was brought under control and rescue operations were carried out to locate and evacuate affected workers.
The injured workers were transported to hospitals for medical treatment. One seriously injured worker later succumbed to his injuries, taking the reported death toll to five.
Cause Under Investigation
The exact cause of the boiler explosion has not yet been officially established. Authorities are expected to investigate the condition and operation of the boiler, maintenance history, pressure-control systems, safety procedures and other factors that may have contributed to the incident.
It is therefore important not to attribute the explosion to a specific technical failure until the official investigation establishes the cause.
Key Industrial Fire & Safety Concerns
A boiler explosion in a manufacturing facility highlights the importance of comprehensive process-safety management.
1. Regular Boiler Inspection
Boilers and pressure equipment require regular inspection, testing and preventive maintenance to identify potential defects before they become critical.
2. Pressure & Temperature Monitoring
Reliable pressure-relief devices, gauges, alarms and automatic shutdown systems are essential to prevent unsafe operating conditions.
3. Preventive Maintenance
Maintenance schedules should be strictly followed, with inspection records properly maintained and any abnormal condition addressed immediately.
4. Emergency Preparedness
Industrial facilities should have clearly defined emergency procedures for explosions, fires, equipment failure and evacuation.
5. Fire Protection Systems
Appropriate fire detection, alarm, firefighting and emergency-response systems should be provided based on the hazards associated with the manufacturing process.
6. Worker Training
Employees should be trained to identify abnormal equipment conditions, raise alarms, follow emergency procedures and evacuate safely.
7. Process Safety Management
High-risk industrial operations require a systematic approach covering hazard identification, risk assessment, equipment integrity, operating procedures, emergency response and continuous safety improvement.
Conclusion
The Sri City pharma factory boiler blast is a tragic reminder that industrial safety depends not only on firefighting arrangements but also on preventing hazardous events before they occur.
Regular inspection of pressure equipment, preventive maintenance, reliable safety controls, proper emergency procedures, fire-protection systems and continuous worker training are essential to protect lives and minimise industrial losses.
Fire safety and industrial safety must work together—from prevention and detection to emergency response and recovery.
