More than 100 staff members and visitors were evacuated from Princess Margaret Hospital in Kwai Chung on Wednesday morning after an unusual odour raised concerns about a possible gas leak inside Block G.
Police and firefighters were called to the hospital at about 9am after the smell was reported on the 12th to 14th floors of the building. Emergency crews began searching the affected area to determine the source of the odour and identify whether an unknown gas had been released.
Hospital authorities moved quickly to clear the affected floors as a precaution. Staff and visitors in the area were instructed to leave the building while emergency personnel assessed the situation.
Unusual Odour Reported On Three Floors
The incident began when an unusual smell was detected on several floors of Block G. The reported area covers the 12th, 13th and 14th floors, where the hospital's pathology department is located.
The Hospital Authority said the affected section does not contain patient services or treatment facilities. That meant the evacuation could be carried out without disrupting treatment areas within the hospital.
Hospital management arranged for people working or visiting on the affected floors to leave the building safely after the odour was reported.
The evacuation involved more than 100 people, including hospital staff and visitors. They were moved away from the affected area while emergency crews carried out checks.
The response reflects the uncertainty surrounding the source of the smell. At the time emergency personnel arrived, authorities had not established what substance had caused the odour or whether it posed a danger to people inside the building.
Firefighters Search For Source
Firefighters arrived at the hospital shortly after the report and began handling the incident. Their work focused on identifying the source of the suspected gas and assessing conditions inside the affected section of Block G.
Police officers were also deployed to the scene.
The hospital is working with the Fire Services Department to investigate where the unknown gas or odour originated. Authorities have not identified the substance involved.
That distinction is important. A suspected gas leak can involve a range of circumstances, and an unusual smell alone does not establish what caused it. Emergency crews therefore need to locate the source before determining the nature and extent of any possible release.
For people inside the building, the immediate priority was to move away from the affected floors and allow emergency personnel to carry out their checks.
No information was provided indicating that patients had been exposed to the substance or that anyone had suffered injuries as a result of the incident.
Hospital Services Continue
Despite the evacuation, emergency services at Princess Margaret Hospital remained unaffected.
The Hospital Authority confirmed that the affected area does not provide patient treatment services. The pathology department is located on the floors involved, but the reported incident did not lead to a wider shutdown of hospital operations.
That allowed other parts of the hospital to continue operating while the investigation proceeded.
The distinction between the affected floors and emergency services is significant for a major hospital, where any disruption can affect patients, medical staff and visitors. In this case, management was able to isolate the reported problem to a specific part of the building while keeping emergency operations running.
The evacuation also allowed firefighters to work in the area without staff and visitors remaining on the affected floors.
Investigation Underway
The exact cause of the unusual odour remained under investigation on Wednesday.
The hospital and Fire Services Department are working together to determine what caused the suspected gas leak and whether there was an identifiable source within Block G.
At this stage, authorities have not announced that a specific gas has been confirmed. They have also not provided details about the concentration of any substance or whether the odour was linked to hospital equipment, materials or another source.
Those questions will form part of the investigation.
Emergency crews must establish not only what produced the smell but also whether any substance escaped into the building and whether further action is necessary. Until that assessment is complete, evacuating the affected floors provides a straightforward precaution while investigators examine the site.
The response also demonstrates why unusual odours in medical facilities are treated seriously. Hospitals contain laboratories, medical equipment, chemicals and other materials, meaning the source of an unfamiliar smell cannot simply be assumed.
For hospital workers and visitors who were asked to leave, the immediate concern was therefore the uncertainty surrounding the source rather than a confirmed identification of a dangerous substance.
No Impact On Emergency Services
Princess Margaret Hospital's emergency services continued to operate despite the incident.
The Hospital Authority's confirmation means the evacuation did not affect the hospital's emergency response areas or prevent patients from receiving emergency care.
The incident remained concentrated in Block G, with the evacuation focused on the 12th to 14th floors where the unusual odour had been reported.
Further information is expected to depend on the findings of the investigation by hospital management and the Fire Services Department.
For now, the central questions are what caused the unusual odour, whether any gas was actually released and whether additional safety measures are required inside the affected part of the hospital.
More than 100 people were moved from the area as a precaution, while emergency crews searched for the source. With hospital emergency services continuing to operate, investigators now face the task of identifying exactly what triggered the alarm and ensuring the affected floors are safe for staff to return.
