APPENDIX B<br />

SOP B6.2<br />

Tank Sampling<br />

Field sampling procedures for collecting samples of tank contents using a Teflon ® bailer with a Teflon ® -<br />

coated stainless steel wire cord or an open-tube sampler are as follows:<br />

Teflon ® Bailer<br />

Open Tube Sampler<br />

Wear appropriate PPE as required in the BWHSP (Appendix F of the BWP) and the SSHP.<br />

Gain access (e.g., steps, ladder, man-lift, etc.) to the top of the tank.<br />

Slowly open release valve (if any) to bring the tank to atmospheric pressure. Properly<br />

control all sources of hazardous energy in accordance with BWHSP (Appendix F of the<br />

BWP) and the SSHP.<br />

Loosen access port/cover bolts and remove port/cover.<br />

If no access port/cover is available, unscrew cap of top opening.<br />

Use of disposable sample equipment is preferred. If disposable sample equipment is<br />

unavailable, use of decontaminated sample equipment is allowed. Sample equipment shall<br />

be decontaminated per the requirements of SOP B1.10, Equipment Decontamination. Insert<br />

a Teflon ® bailer into tank slowly to allow stratified content (if any) to fill the bailer.<br />

Retrieve the bailer and wipe it with a disposable absorbent pad (place the pad in a 55-gallon<br />

drum).<br />

Transfer the sample(s) into appropriate containers as required by the project-specific<br />

addenda.<br />

Repeat the previous step until enough sample volume is obtained, as required.<br />

If using bottom valve, place the sample container below the valve and turn the valve slowly<br />

and easy to ensure a slow, controlled flow of sampling material.<br />

Cap the sampler container, place in double plastic bag, attach label, record all pertinent data<br />

in the field log book and complete the C-O-C form.<br />

Preserve and/or place sample(s) on ice, if required.<br />

Prepare sample(s) for delivery to the laboratory within 24 hours of collection.<br />

Use of disposable sample equipment is preferred. If disposable sample equipment is<br />

unavailable, use of decontaminated sample equipment is allowed. Sample equipment shall<br />

be decontaminated per the requirements of SOP B1.10. Insert a sampler into tank until it<br />

reaches the bottom.<br />

Place thumb securely over open end of tube and carefully retrieve the sampler.<br />
