Kerala Oil Spill Incident 2025
- The Liberian-flagged cargo ship, MSC ELSA 3, overturned off the Kerala coast.
- The ship had transported diesel, furnace oil and hazardous goods such as the calcium carbide.
- Three Coast Guard vessels, Vikram, Saksham and Samarth, have been deployed in a pollution response configuration in the area.
- When the calcium carbide comes into contact with water, it undergoes a highly exothermic reaction, generating acetylene gas and calcium hydroxide.
- The heat released during this reaction can be significant, and the acetylene gas formed is extremely flammable.
- The calcium hydroxide produced increases water’s alkalinity, which can disrupt aquatic ecosystems by altering pH levels.
