Special effects color powder at a water park near Taipei, Taiwan, suddenly ignited into a fireball and blasted into a crowd on Saturday. 498 people attending the “Color Play Asia” party at Formosa Water Park were reportedly injured.
Some victims sustained skin burns covering up to 80 percent of their bodies, Reuters reported.
Taipei health official Lee Lih-jong told Agence France-Presse that many suffered damage to their respiratory organs by inhaling the flammable colored powder.
Nearly 200 people remain in intensive care, but so far there have been no fatalities.
Taiwan’s President Ma Ying-jeou visited injured victims and their families at Taipei Veterans General Hospital on Sunday.
Deputy fire chief Chen Chung-yueh told AFP he suspects the powder may have been ignited by sparks from nearby machinery.
The organizer of the party and the hardware engineer responsible for lighting are both being held for questioning, CNN reported.
Eric Chu, the mayor of New Taipei, told reporters he has ordered the park to be closed until further notice.
