The Industrial Estate Authority of Thailand (IEAT) Governor Veerapong Chaiperm said officials from the Forensic Science Office had inspected six plants of BST Elastomers Co, a subsidiary of BST Group, which are located near the BST petrochemical factory.
Mr Veerapong said the damage found at nearby plants were mostly in tiles, roofs, door panels, windows, mirrors, and ceilings, while other systems including safety, electricity, flare and vent, air pollution control, were not impacted by the explosion and fire and were functioning normally.
Concerning the other incident of chemical leak on the same weekend at the Aditya Birla Chemicals (Thailand) factory in the Hemaraj Eastern Seaboard Industrial Estate, IEAT officials found that there was a problem in the chlorine control valve of the hydrochloric production unit. The entire system was then shut down for safety reasons.
Last Saturday’s explosion and fire at the Bangkok Synthetics Co (BST) petrochemical factory killed 12 people and affected over 100 others, while last Sunday's chemical leak at the Aditya Birla Chemicals (Thailand) affected at least 40 workers and bystanders with dizziness.
