Case Study Analysis: The Unfortunate Chemical Industry Accident

On June 3rd, 2020, a devastating explosion rocked a chemical factory situated within the SEZ precincts of Gujarat. The blast tragically claimed the lives of 10 workers and left nearly 50 with serious injuries. The aftershock of the explosion was so severe that it necessitated the evacuation of a neighbouring village.

Preliminary investigations revealed that the explosion was triggered by the inadvertent blending of two highly reactive chemicals - Dimethyl sulfate and Nitric acid. Their interaction results in an exothermic reaction, meaning it emits a significant amount of heat. This unexpected thermal release drastically elevated the tank's internal pressure, leading to the calamitous explosion.

Further inquiries spotlighted serious lapses in protocol and training. The contractual worker at the helm, unfortunately, lacked the requisite expertise and training to handle these volatile chemicals safely. His inability to correctly identify the appropriate tanks for chemical offloading further compounded the risk. Complicating matters, a hydrogen trolley, positioned precariously close to this tank, became engulfed in the ensuing flames and subsequently detonated, amplifying the disaster's magnitude.

A deeper analysis highlighted that the root cause of this accident was multifaceted. Predominantly, it was the management's laissez-faire attitude towards the stringent handling, control, and flow of hazardous chemicals, coupled with the deployment of an inadequately trained workforce.

Reflecting on the tragedy, several preventative measures come to light:

• Risk Assessment: Before any operation, a detailed risk assessment should have been undertaken by an individual possessing the requisite expertise and experience.
• Training and Supervision: Comprehensive LOTO training, encompassing standard operating procedures and emergency protocols, should have been imparted to all staff, including contractual workers. Effective supervision would have further mitigated risks.
• Positive Isolation: Employing a robust system like double block valves and bleeding would have ensured the positive isolation of process lines.
