U.S. senators seek federal probe of Takata-linked explosion

Two U.S. senators on Wednesday called on the National Transportation Safety Board to investigate the Aug. 22 crash and explosion of a truck carrying Takata Corp air bag parts that killed a woman and injured four others.

Takata makes air bag inflaters containing ammonium nitrate, which have been linked to at least 14 deaths and more than 150 injuries and resulted in a massive vehicle recall.

The NTSB 'must investigate this incident and determine whether this company took appropriate precautions,” said a statement by Senators Richard Blumenthal of Connecticut and Edward Markey of Massachusetts, both Democrats.

The NTSB did not immediately respond to a phone call asking if the agency will begin the investigation sought by the two senators.
