The K-25 Building has been shut down since the mid 1960's. Maintenance activities continued to decrease over time. Ventilation systems are inactive and metal plates have been welded over ceiling openings in some vaults due to security requirements. The roof is in need of repair and there is a continual problem with water leaking into the vaults. The accumulation of moisture and the lack of ventilation were ideal conditions for the growth of mold, fungi, and bacteria.
Most vaults are radiologically controlled areas.
As part of the For-Cause Review, a subteam was formed to review the classification of the identified respiratory illness cases and to examine the various interfaces between those involved in the diagnostic, investigation, and OSHA injury and illness classification processes. It was determined that a written diagnostic protocol for classifying respiratory illnesses associated with the vaults was needed and that detailed technical information should be communicated to offsite physicals to whom employees are referred. Industrial hygienists, Health Services and pulmonary physicians met and a clearer understanding of how health services and industrial hygiene could help these specialists provide the most effective care to the employees was established. The pulmonary physicians also determined that a first-hand visit to the vaults would help them in their treatments of the employees. Occupational physicians and medical staff should make regular visits to the work sites and plant facilities to become familiar with employee job tasks, work site environments, and existing or potential health hazards.
