Danish facility management group ISS says its Hong Kong unit which was the property manager for fire-ravaged Wang Fuk Court played no role in the renovation work suspected of being behind the deadly blaze.

The group's shares plunged about 8 percent on Tuesday after it was named in a South China Morning Post report.

In a statement, ISS said its Hong Kong property management unit, ISS EastPoint Properties (ISS EPPL), provided administrative support for the incorporated owners of Wang Fuk Court, adding that its work included "arranging for services to be carried out by third-parties" and managing day-to-day security services on-site.

But the Danish group said its unit was not involved in appointing the contractor for the renovation project or overseeing the work carried out.

"That responsibility rests with the appointed professional consultant and the registered construction contractor," the statement said.

It also said the third parties in question were selected by the owners and its involvement in the tendering process for the renovation project "was administrative".

"It did not extend to making recommendations or the decision-making process," the statement said.

ISS also said it did not conduct the installation, maintenance or inspection of fire safety equipment at Wang Fuk Court.

"In Hong Kong, by law, these services must be undertaken by a licensed registered contractor. As the service agent ISS EPPL arranged for these services to be completed by the contractor in compliance with the relevant laws and regulations," it said.

ISS said it will support the judge-led committee tasked with investigating the fire.

"Our focus now is continuing to support those affected and ensuring authorities have the information they need," it said, while also expressing its condolences to the victims.
