One of Hanford’s most challenging projects continues to be the safe management of approximately 56 million gallons of radioactive and chemically complex waste stored in underground tanks. One potential hazard of concern in the tank farms is the presence of chemical vapors released from the tanks, which may enter workers’ breathing spaces. Strict controls are implemented to ensure workers are protected from exposure.
With worker safety the top priority, WRPS uses a hierarchy of controls to manage hazards in Hanford’s tank farms. This system, used industry wide by numerous safety organizations, strives to minimize or eliminate exposure to hazards.
The following controls have been implemented by WRPS:
- Elimination and Substitution of Hazards
- Engineering Controls
- Administrative Controls
- Personal Protective Equipment
