Health fears have workers at Hanford seeking answers By Hal Bernton, Seattle Times
Bechtel officials have not required workers to wear any special protective gear. But Bechtel recently decided to install a new network of chemical monitors on the site. Those monitors will test for ammonia, nitrous oxides, volatile organic compounds and also include a portable infrared unit to test for 150 other chemicals.
'We have thought that we were protected by distance and have no evidence of any harmful tank vapors,' said John Britton a Bechtel spokesman. 'But we are taking employee concerns seriously.'
The waste at the Hanford nuclear reservation is among the most hazardous in the world and includes a complex melange of liquids, thick slurries and saltlike cakes.
The waste-treatment project managed by Bechtel broke ground in October 2001. Employing more than 1,500 workers, this is the largest federal construction project in the United States and is expected to take 10 years to complete.
