Chemicals at a factory just outside the Thai capital burst back into flames briefly Tuesday, sending up another cloud of toxic black smoke and highlighting the continuing health danger from an industrial accident that killed one and injured dozens more.
Extinguishing the first blaze took more than 24 hours after it started with an explosion about 3 a.m. Monday that could be heard for kilometers (miles) and blew out the windows and doors of nearby homes.
Firefighters continued to douse the site with water and foam to keep the highly flammable chemical styrene monomer from reigniting, but flames broke out again and burned for about an hour Tuesday afternoon.
