Officials found a 4 cm crack in an underground fuel pipe under Chuea Phloeng Road in Klong Toey after a 13-day search. Oil leaked into drains and residents complained of fuel smell. The pipe cracked after soil subsided beneath an expressway pillar. Governor Chadchart has ordered leak checks at similar installations where ground conditions match. For a small business, the practical impact is limited: watch for fuel smells or oil sheen near your premises and report it to officials.
