Safety Alert - Incident High Consequences ( IHC) - Pharma factory blast on 30.06.2025
Dear Team ,
As you all are aware about the Incident High Consequences ( IHC) had occurred at Pharma factory blast on 30.06.2025 - What caused the explosion that deceased 42 people.
Incident Description :
A powerful explosion tore through a pharmaceutical factory on 30th June '2025 , Monday morning, leaving at least 42 people dead and many others injured.
What Happened :
As per preliminary investigations, a sudden pressure build-up inside a spray-drying unit may have caused the massive explosion, leading to the collapse of a three-storey building at the pharmaceutical factory, the blast occurred in the factory’s Microcrystalline Cellulose (MCC) drying unit. MCC is a refined, partially broken-down form of cellulose derived from fibrous plant material like wood pulp. It’s widely used in the pharmaceutical industry as a key excipient in tablets and supplements. It also finds use as a bulking agent in food production.
Why did it Happened :
The spray dryer, where the explosion reportedly happened, is a machine that converts a liquid or slurry into a dry powder by spraying it into a stream of hot gas. Since this process generates extremely high temperatures, a blow air handler is used to control the heat and airflow within the system. The impact was so severe that the entire three-storey building came crashing down in seconds.
However, experts believe the blow air handler may not have been properly cleaned or maintained, leading to a dangerous rise in temperature. Initial investigation officials say this overheating may have pushed temperatures as high as 700 to 800 degrees Celsius, far beyond safe limits, causing the explosion.
Incident Investigation team has been formed by The state government has constituted a five-member committee to investigate the cause of the explosion and recommend safety measures
