Radiological Training for Tritium Facilities
Student's Guide
Notes
A. Engineered Controls
1.
Containment and Confinement
Containment or confinement is a
series of physical barriers, minimizes
exposure of workers.
Confinements such as glove boxes are
almost always used when handling
large quantities of tritium. However,
hoods are acceptable for handling
small quantities, such as in a
laboratory.
2.
Airflow
Maintaining negative ventilation is
essential for the safe operation of a
tritium facility. Airflow should be
from areas of LEAST to MOST
3.
Local Exhaust Ventilation
The primary advantage of local
exhaust ventilation techniques is the
removal of airborne tritium,
regardless of its release rate or
chemical or physical form. In
addition, these techniques use
relatively low volume rates compared
to normal ventilation requirements.
