Mumbai: A routine elevator ride in a Goregaon residential building turned into a frightening incident after a bundle of balloons being carried by a man suddenly burst into flames inside the lift, leaving two people with burn injuries. The entire episode was captured on CCTV and has since drawn attention to the dangers of using flammable gas in balloons.

According to police officials, the incident occurred in a multi-storey building in Goregaon, a western suburb of Mumbai. A woman and a balloon seller who were inside the elevator at the time of the blast sustained burn injuries. A case has been registered against the balloon seller, and an investigation is underway to determine the exact cause of the fire and the type of gas used to fill the balloons.

CCTV footage captures moment of fireball

CCTV visuals from inside the elevator show a woman in a white shirt entering first, pulling a small trolley bag. She appears to press the button for her floor and waits as the doors remain open.

Moments later, a man carrying a large polythene sack filled with more than a dozen balloons attempts to enter the lift. The woman notices his difficulty and steps aside to make space. The man then squeezes into a corner of the elevator with the balloon bundle.

Just as another man in a black shirt is about to enter, a sudden flash erupts from the balloon cluster. Within a fraction of a second, the balloons explode into a large fireball that fills the elevator cabin. For a brief moment, the flames obscure the camera’s view completely.

Seconds later, the footage shows the woman and the balloon seller rushing out of the lift in panic. The balloon seller appears to lose balance and stumbles as he exits. The third man, who was about to enter, narrowly escapes being caught in the blast because he had not fully stepped inside.

Injuries reported, case registered

Police said both the woman and the balloon seller suffered burn injuries. They were given medical attention, though the exact severity of their injuries has not been officially detailed. No fatalities were reported.

A police complaint has been filed, and a case has been registered against the balloon seller for negligence and endangering public safety. Officers are examining whether safety norms were violated and whether hazardous materials were being transported improperly inside a public-use elevator.

Authorities are also reviewing the CCTV footage frame by frame as part of the probe. Statements from witnesses and building management are being recorded.

Suspicion over type of gas used

Investigators are focusing on the type of gas used to inflate the balloons. Experts note that standard helium balloons are non-flammable and generally safe under normal handling conditions. However, hydrogen-filled balloons — sometimes used as a cheaper alternative — are highly flammable and can ignite with even a small spark or static discharge.

Police officials said it is not yet confirmed whether the balloons involved in the incident were filled with hydrogen or another flammable gas. Samples and remains from the burnt balloon material may be tested to determine the composition.

Safety experts point out that hydrogen balloons, when clustered together in a confined space such as an elevator, can create a highly combustible environment. A minor ignition source — such as static electricity, friction, or an electrical spark — can trigger a sudden flash fire.

Elevator safety and transport risks highlighted

The incident has raised concerns about carrying potentially hazardous materials in enclosed public spaces like lifts. Fire safety officers say elevators are particularly vulnerable because they are compact, electrically operated enclosures with limited ventilation.

Housing society associations across Mumbai often have guidelines restricting the transport of gas cylinders, chemicals and flammable materials in passenger lifts. However, items like party balloons are rarely checked, as they are generally assumed to be harmless.

Following the Goregaon incident, some residential complexes are reviewing their safety advisories regarding vendors and delivery personnel carrying bulk materials inside elevators.

Officials urge caution with balloon vendors

Police and civic officials have advised citizens to be cautious when hiring balloon vendors for events and celebrations. They recommend confirming that balloons are filled with helium sourced from authorised suppliers and not with cheaper, dangerous substitutes.

Vendors, too, may face stricter scrutiny if found using prohibited or unsafe gas-filling methods. Authorities are expected to issue fresh reminders and possibly safety circulars to event decorators and street balloon sellers.

Investigation continues

Mumbai Police said further action will depend on forensic findings and medical reports of the injured persons. If the gas used is confirmed to be flammable and improperly handled, additional charges may be added.

The Goregaon elevator fireball incident serves as a stark reminder that seemingly harmless celebration materials can pose serious risks when safety norms are ignored. Officials have urged both vendors and the public to follow proper safety practices to prevent similar accidents.
