ABSTRACT:
Do I anticipate something going wrong? No. But even in a controlled burn, things occasionally go wrong."
He said the burning of the house would provide "an amazing textbook study" for bomb technicians in the future.
San Diego County authorities plan to burn the home Wednesday but need near perfect weather, with no rain, no fog, and only light winds blowing toward the east, away from the city. They have warned residents in the danger zone that they will be given less than 24 hours notice to evacuate their homes for a day, and that nearby Interstate 15, connecting the area to San Diego, will be closed.
Gov. Arnold Schwarzenegger has declared a state of emergency, and hospitals will be on standby in case there is a rash of people getting sick, Newman said.
Some 40 experts on bombs and hazardous material from across the country and at least eight national laboratories are working on the preparations.
They have analyzed wind patterns to ensure the smoke will not float over homes beyond the scores that will be evacuated. They have studied how fast the chemicals can become neutralized under heat expected to reach 1800 degrees and estimate that could happen within 30 minutes, which means most of the toxins will not even escape the burning home, Newman said.
The county has installed 18 sensors that will measure the amount of chemicals in the smoke and send the data every two minutes to computers monitored by the fire and hazardous material departments.
Experts also have mapped how far the plume will travel and predict it will not go beyond Interstate 15. They calculate that if there is an explosion, it would probably throw the debris only about 60 feet.
