NTSB hearing is a primer on safety

Noon Update: The NTSB concluded the three-day hearing into the crash right at noon Thursday. The safety board has not issued a formal finding on the cause of the crash but officials anticipate doing that by the one-year anniversary of the accident on June 22.

In his closing remarks, hearing chairman Robert L. Sumwalt thanked the 21 witnesses who delivered testimony over the past three days and quoted from a saying he said they have at the NTSB: "From tragedy we draw knowledge to improve the safety of us all."

We were "here to learn from this tragedy, so that it does not happen again," he said, before adjourning.

Day Three of the NTSB hearing into the Red Line crash began at 8 a.m. Thursday. The focus today is on testimony from "high reliablility organizations,'' which one of the witnesses partially described as organizations or groups of organizations that conduct "relatively error-free operations."

The plan seems to be to present examples of organizations that have had success implementing HRO programs, such as commercial aviation and some programs with the U.S. Department of Energy. One of the witnesses scheduled includes an engineer with a company that helps manage the nation's nuclear weapons stockpile.

Dr. Karlene Roberts, director of the Center for Catastrophic Risk Management at the University of California, Berkeley, set the stage for much of Thursday's testimoney, describing HRO's and giving a brief preview. The center's mission, according to its Web site, is "through multidisciplinary research, teaching and outreach, to help societies cope better with catastrophic hazards including hurricane, tornado, flood, tsunami, earthquake, volcano, landslide, wildfire, pandemic, industrial accident, chemical spill, blackout and terrorism attack." The Web site says the center was created in September 2005 after Hurricane Katrina.

Roberts spoke of "latent errors" that can precipitate an organization's downward slide. She said a "lack of resources" and "deferred maintenance" may be latent errors affecting Metro. "That tends to bubble up and bite you," she said.
