U.S. safety investigators, acting in response to a deadly California gas line explosion, urgently recommended on Monday that pipeline operators review their records to ensure their systems were built correctly.

The National Transportation Safety Board recommendations, which also seek cooperation from state and federal regulators, address potential recordkeeping problems investigators fear could create conditions in which a pipeline is operated at a higher pressure than designed to withstand.

The NTSB wants regulators to ensure that records, surveys and documents “accurately reflect the pipeline infrastructure” as constructed nationally so that operating pressures are calculated properly.
