3.0 PRECAUTIONS AND LIMITATIONS

NOTE - During the performance of this procedure no vapor hazard exists, therefore no

respiratory protection for IH purposes is required.

3.1 Personnel Safety

3.1.1 Non-electrical worker accessing electrical enclosures must ensure the

following:

The enclosure must have a white label indicating that it has been evaluated.

The work activity within the enclosure does not involve.

- Reaching around or moving electrical equipment

- Contacting electrical connectors/connections

- By-passing protective shielding/barriers.

3.1.1.1 Stop and notify management if these conditions cannot be met, or

if discrepancies exist (e.g. conflicting or missing labels, missing

or damaged protective barriers).

3.1.2 When environmental conditions exist where extreme cold or damp weather

conditions could potentially cause condensation to form inside the ventilation

system (outside ambient temperature is less than 50 degrees F and the

exhauster has been shut down for longer than 30 minutes), absorbent

materials should be placed around the filter paper connection when changing

out filter paper. This will help to ensure liquids do not drip on electrical

components/insulating barriers and maintains the electrically safe condition.

3.1.3 If liquids run down onto electrical components/insulating barriers, exit the

cabinet, and notify the Shift Manager that the cabinet must be reevaluated for

electrical hazards.

3.1.4 When liquids are present or handling the absorbent materials, workers need

to wear surgeons’ gloves.

3.2 Equipment Safety

CAUTION - To prevent cross contamination of record or CAM sample paper, paper

should not be removed from proper envelope.

3.3 Radiation and Contamination Control

3.3.1 When work is performed in a high contamination, high radiation, or airborne

radioactivity area, then an approved work package must be developed which

is reviewed by Radiological Control per the ALARA Work Planning

procedure TFC-ESHQ-RP_RWP-C-03.

3.4 Environmental Compliance

3.4.1 All planned and unplanned outages of Tank Farm ventilation systems,

abatement control equipment, and exhaust monitoring systems must be

reported to the applicable shift office per TF-REC-001.

3.4.2 A comprehensive inspection is performed at the beginning of each sampling

period or quarterly, whichever is less to satisfy requirements of TFC-ESHQ-

ENV-STD-05, Radioactive Airborne Effluent Sampling.

3.4.3 Discovery of a “wet” or “damp” sample filter at the time of exchange should

be reported to the Environmental Representative for the facility. At the time

of reporting provide the sample identification number for the “wet” or

“damp” sample filter.

5.0 PROCEDURE

NOTE - Sections 5.1 through 5.3 may be performed simultaneously or in any logical

order, unless otherwise noted in this procedure.

- There are electrical interlocks and relays in the system that, if activated or

overridden, can shut down exhaust and detection systems; therefore, attention

must be given to exact step-by-step compliance to applicable sections being

performed.

5.1 Use and Notifications

5.1.1 IF at any time during the performance of this procedure any item is identified

as out-of-specification per the referenced requirement(s), or in the judgment

of the HPT an identified condition may render the CAM inoperable,

NOTIFY Shift Manager of the out-of-specification condition.

5.1.2 IF during sample exchange exhaust stack shuts down, IMMEDIATELY

NOTIFY Shift Manager.
