The incident occurred at the HPCL Patalganga LPG Bottling Plant in the Additional MIDC area of Chavane village, Panvel taluka. Floodwater entered the facility during intense rainfall and carried an estimated 3,000 cylinders into the river, prompting a major public-safety warning from the district administration.
Raigad District Collector Kishan Jawale appealed to residents not to touch, open, move, collect or take home any cylinder found in the river, along the riverbank or in nearby areas. Authorities said it is not known whether the cylinders washed away contain LPG or whether they remain safe after being carried by floodwater.
The collector warned that handling a recovered cylinder could be extremely dangerous. People have been asked to immediately inform the authorities if they see a cylinder in or near the Patalganga River instead of trying to pull it out or transport it themselves.
The incident has raised concern because LPG, or Liquefied Petroleum Gas, is highly flammable. A cylinder that has been damaged by strong water currents, debris, rocks or impact may pose a risk if it leaks. Even if a cylinder appears normal from outside, its valve, seal or body may have been affected during the flooding.
Officials have stressed that the public should not assume that a cylinder is empty. The cylinders washed away reportedly include both filled and empty units, and authorities are carrying out an assessment to determine their condition and trace their locations.
The HPCL facility is located at Plot No. E-1/7 in the Additional Patalganga Industrial Area in Chavane village. Government environmental-clearance records identify the site as an LPG bottling plant project in Panvel, Raigad district.
Heavy rainfall in the region caused water levels to rise sharply, creating strong currents in the Patalganga River. The floodwater reportedly entered the bottling plant and swept the cylinders away before they could be secured.
Videos and reports from the area showed cylinders moving in the river water, leading to concern among residents living downstream. Authorities fear that some cylinders may have drifted toward riverbanks, low-lying fields, bridges, nearby settlements or other areas connected to the river’s flow.
The district administration has asked residents in affected areas to remain alert. Anyone who sees a cylinder has been advised to keep a safe distance and report it to police, the fire brigade, HPCL, an authorised HPCL LPG dealer or designated government offices.
According to the district administration’s instructions, recovered cylinders can be handed over to HPCL, the nearest authorised HPCL LPG dealer, the Tahsildar offices at Khalapur or Pen, or the office of the Sub-Divisional Officer in Pen. The administration has urged people not to retain or tamper with cylinders recovered from the floodwater.
The warning is particularly important because people may be tempted to collect cylinders that reach the riverbank. Authorities have made it clear that taking a cylinder home for personal use, opening it, checking it or trying to sell it could create a serious risk.
LPG cylinders are designed for safe household and commercial use when they are properly stored, inspected and handled by trained people. However, cylinders exposed to floodwater can face additional risks. Fast-moving water can cause cylinders to collide with hard objects, while mud and debris can affect the valve area.
If a cylinder is leaking, people may smell the strong odour added to LPG for safety detection. In such a situation, residents should move away from the area, avoid flames, cigarettes, lighters, electrical switches and vehicle ignition near the cylinder, and contact emergency services immediately.
The administration has also advised people not to gather near the river merely to watch the cylinders. Strong river currents during heavy rain can be dangerous even without the presence of LPG cylinders. People near the riverbank could face risks from sudden water-level changes, slippery ground and floating debris.
The recovery operation is expected to involve coordination between HPCL, the Raigad district administration, police, fire services and local emergency teams. Officials will likely monitor river stretches downstream and inspect areas where cylinders may have become stuck.
The priority is to recover the cylinders safely before they reach populated areas or create a possible fire hazard. The exact number of cylinders recovered and the condition of each cylinder will be known only after the recovery and inspection process is completed.
The incident has also highlighted the importance of disaster preparedness at industrial facilities located near rivers and flood-prone areas. LPG bottling plants store and distribute large numbers of cylinders, making emergency planning essential during the monsoon season.
Industrial facilities must prepare for extreme weather by monitoring rainfall alerts, securing hazardous materials, checking drainage systems and keeping emergency teams ready. Floodwater can quickly turn a local weather event into a larger public-safety challenge when it affects fuel, chemical or industrial storage sites.
Raigad district, located in Maharashtra’s Konkan region, often receives heavy monsoon rainfall. During intense rain spells, rivers and streams can rise quickly, while roads, industrial zones and low-lying villages may face flooding.
For local residents, the most important message remains simple: do not touch any LPG cylinder found in the Patalganga River or nearby areas. Do not attempt to retrieve it, open it, use it or take it home.
The district administration has asked people to report such sightings immediately so trained teams can handle the situation safely. Authorities are continuing to assess the incident and trace the cylinders swept away by the floodwater.
