SEATTLE -

The attorney representing families of six workers killed in a 2010 explosion at Tesoro's Anacortes oil refinery have settled a lawsuit against Tesoro and Shell Oil Co.

Attorney David Beninger tells KING-TV (http://is.gd/lhMASm ) the wrongful death suit was settled last month for around $39 million and the money was divided among the families.

The lawsuit claimed Tesoro and Shell, which previously owned the facility, ignored dangerous conditions that led to the blast. Seven workers were killed. A contractor who was burned but survived also joined the suit.

Beninger says a separate suit against Lloyd's Register Energy, hired to examine equipment, is still scheduled for trial later this year.

The Chemical Safety Board is holding a public listening session in Anacortes Thursday to present the results of its investigation and offer safety recommendations.
