The provincial industry office ordered the dock closed for 30 days pending the outcome of the investigation and safety improvements, Ayutthaya Governor Rewat Prasong said. He said Labour Ministry officials would provide aid to the families of the deceased workers in accordance with the law.

Killed were a Thai national and three documented Cambodians.

Dock owner Chatchai Sonmafeung said the dock obtained a proper licence and would cooperate with the police investigation.

Chatchai will host funerals for the deceased workers at Wat Kok Kaew Burapha as well as pay compensation to their families. He believed the explosion was an accident.
