h.
Use good housekeeping practices; clean up during and after jobs.
"Good Housekeeping" is a prime factor in an effective contamination control
program. Each radiological worker should keep his/her work area neat and clean to
control the spread of contamination.
i.
Use standard contamination control procedures as established by the Radiological
Control Organization.
1)
Do not violate contamination area ropes or barricades.
2)
Frisk materials out of contamination areas as directed by site procedures.
3)
Use change areas and step-off pads as directed.
4)
Do not pass items out of contamination areas without following site procedures.
5)
Be alert for potential violations to contamination control procedures.
j.
Ensure ventilation systems are operating as designed (i.e., no unauthorized
modifications).
k.
Radiological workers should always ensure that the proper entry, exit, and equipment
control procedures are used to avoid the spread of contamination. Comply with
procedures!!
2.
Engineering controls
a.
Ventilation
1)
Systems and temporary spot ventilation (e.g., temporary enclosures with HEPA
filters) are designed to maintain airflow from areas of least contamination to
areas of most contamination (e.g., clean to contaminated to highly contaminated
areas).
2)
A slight negative pressure is maintained on buildings/rooms/enclosures where
potential contamination exists.
3)
High efficiency particulate air (HEPA) filters are used to remove radioactive
particles from the air.
b.
Containment
Permanent and temporary containments are used for contamination control.
Examples include vessels, pipes, cells, glovebags, gloveboxes, tents, huts, and plastic
coverings.
