The number of party revellers injured in a fire at a Taiwan water park rose to 519 on Sunday, as authorities began investigating the cause, suspected to be a sudden explosion of a coloured powder thrown on those attending the party.
Six foreigners and seven visitors from Hong Kong, mainland China and Macau were among those injured after about 1,000 people dancing at Saturday’s event were sprayed with the powder, as a special feature of a festival also held in previous years.
The blaze, which broke out around 8.30 p.m. at the Formosa Fun Coast water park on the outskirts of the capital, Taipei, is suspected to have been caused by an explosion of the coloured powder, local government official Lin Chieh-yu told Reuters.
“It remains under investigation as to what made the powder explode,” he added, however.
Authorities have banned the use of the powder until the investigation is completed and its safety can be assured.
“The next few days will be a critical time for the injured,” Taiwan Premier Mao Chi-kuo told reporters. Of the 519 injured, 419 are still being treated in 41 hospitals across the island.
In the immediate aftermath of the explosion, rescuers treated hundreds of people, most of them aged between 20 and 30, who wore wet swimsuits and lay on inflatable plastic doughnuts.
A video posted online by Apple Daily showed dancers in front of the stage engulfed in clouds of coloured powder a moment before a fireball erupted, followed by pockets of flame, triggering panic and screams.
“There was blood and people were on fire,” one injured man said.
No death has yet been reported, but victims suffered burns on limbs and torsos, with some passing out from the pain while others had burned clothes stuck to their skin, media reports and pictures showed.
“Her whole life is ruined,” sobbed the father of Chu Li, an 18-year-old girl with burns on 80 percent of her body, during a visit by President Ma Ying-jeou to victims in a Taipei hospital.
Soldiers, army vehicles and medical services joined the rescue effort, while hospitals in four municipal precincts, along with Taipei, are treating sufferers.
The amusement park has been closed temporarily, it said on its website on Sunday.
Taipei has sweltered in temperatures exceeding 30 degrees Celsius (86 degrees Fahrenheit) in recent weeks.
