Thiruvananthapuram : Three people suffered burn injuries after a fire broke out inside a well near a petrol pump at Kallambalam in Thiruvananthapuram district on Thursday.
The incident occurred after fuel from an underground storage tank at a nearby Indian Oil petrol pump reportedly seeped into a well on an adjoining property. The well was subsequently being cleaned when accumulated petrol vapour caught fire, seriously injuring three people.
According to reports, the injured were identified as Kallambalam natives Vineeth, Rakesh and Sunu. Vineeth and Rakesh suffered serious burns and were shifted to the intensive care unit of Thiruvananthapuram Medical College Hospital, while Sunu was admitted to Attingal Taluk Hospital.
Fuel leaked into nearby well
Preliminary information indicates that the incident was linked to a fuel-handling error at the petrol pump.
Reports said petrol was mistakenly filled into an underground tank that already contained diesel, causing the tank to overflow. The leaked fuel reportedly travelled into a nearby well, contaminating the water and creating a potentially dangerous concentration of fuel vapour inside the confined space.
The contamination was noticed after the well was affected by the leaked fuel. The petrol pump owner reportedly arranged for workers to clean the well following a complaint from the property owner.
The workers first removed the contaminated water from the well. The subsequent attempt to check conditions inside the well resulted in the accident.
Flame ignites petrol vapour
The workers reportedly used a candle or flame to check the conditions inside the well after the contaminated water had been pumped out.
When the flame came into contact with petrol vapour accumulated inside the confined space, it ignited suddenly.
The resulting fire caused burn injuries to the three people present at the site. Reports said the victims suffered burns to areas including their faces, hands and abdomen.
The incident highlights the serious risks associated with flammable vapours in enclosed spaces. Even after visible liquid fuel has been removed, vapours can remain trapped in a confined area and ignite when exposed to a flame or other ignition source.
Two injured shifted to ICU
The injured were rushed to hospitals following the accident.
Vineeth and Rakesh, who sustained serious burns, were taken to Thiruvananthapuram Medical College Hospital and admitted to the ICU. Sunu was shifted to Attingal Taluk Hospital for treatment.
The condition of the two seriously injured workers has made the incident particularly concerning for their families and the local community.
Authorities are expected to assess the circumstances surrounding the accident, including the source of the fuel leak and the safety measures followed while attempting to clean the contaminated well.
Police begin investigation
Kallambalam Police have registered a case and begun an investigation into the incident.
Officials are expected to examine how fuel entered the well, whether the storage tank was correctly filled and whether appropriate safety precautions were followed before workers entered or attempted to inspect the well.
The investigation is also likely to look into the circumstances surrounding the reported fuel mix-up and the subsequent cleaning operation.
The petrol pump owner has reportedly attributed the incident to an error by the driver of the fuel tanker that supplied the station. The owner also claimed that the incident resulted in losses estimated at around ₹12 lakh. These claims will be subject to verification as part of the investigation.
Incident raises safety concerns
The accident has raised concerns among residents about the dangers posed by fuel leaks near residential properties.
Petrol is highly volatile, and its vapour can accumulate in enclosed or poorly ventilated spaces. A well contaminated by fuel can therefore become extremely hazardous even when there is no visible fire or obvious sign of danger.
The Kallambalam incident demonstrates how a seemingly routine cleaning operation can turn dangerous when the presence of flammable substances is not properly assessed.
Experts and safety authorities generally emphasise that confined spaces containing suspected fuel contamination require specialised procedures and equipment. Sources of ignition, including open flames, must be avoided when flammable vapours may be present.
Need for proper safety assessment
The incident also highlights the importance of detecting and containing fuel leaks at the earliest stage.
Petrol stations use underground storage systems, making it essential that fuel transfer and storage operations are carried out carefully and that any suspected leakage is investigated promptly.
When fuel contamination reaches surrounding soil or water sources, the risks can extend beyond the petrol station itself.
In Kallambalam, the reported spread of fuel into a nearby well resulted in a dangerous situation for people who were attempting to remove the contamination.
The incident therefore underlines the need for proper coordination between property owners, fuel station operators and trained safety personnel when dealing with suspected fuel contamination.
Investigation to establish exact cause
Officials will now have to determine the sequence of events that led to the fire.
This includes establishing how the fuel entered the well, whether the tank was filled with the correct fuel, how the contaminated water was removed and why an open flame was used during the cleaning operation.
The findings could help determine responsibility and whether additional safety measures are required at the petrol station and surrounding properties.
For the three injured people and their families, however, the immediate priority remains medical treatment and recovery.
The Kallambalam accident serves as a stark reminder that fuel vapours can pose a serious danger even when there is no visible fuel or flame. Proper safety procedures, professional assessment and the avoidance of ignition sources are essential when dealing with suspected fuel contamination.
As the police investigation continues, authorities will also be expected to examine whether the incident could have been prevented and whether corrective measures are needed to ensure the safety of residents and workers in the area.
