1.0 INTRODUCTION
This Sampling and Analysis Plan is prepared as part of the Polychlorinated
Biphenyl (PCB) Management Plan of Medical Center of Digos Cooperative. It
documents the protocols for sampling and analysis of PCBs and covers all
equipment and materials owned by Medical Center of Digos Cooperative that are
subject for sampling and analysis.

3.0 PROTOCOLS FOR SAMPLING PCBS
This section presents the following protocols for sampling PCBs:

Sampling procedures

Health and safety protocols

Sample preservation procedures

Quality assurance (QA) and quality control (QC)


All sampling activities needed as part of Medical Center of Digos Cooperative’s
management of PCBs shall be conducted by (_______________), while adhering to the
aforementioned protocols, which are further discussed in the succeeding
subsections.

Sampling and Analysis Plan 2015
Medical Center of Digos Cooperative
3.1 SAMPLING PROCEDURES
(___________________________) will collect oil samples of sufficient volume such that
it represents the PCB concentration of an equipment possibly containing PCBs. In
doing so, the following procedures will be followed:
a. Remove the lid of the transformer.
b. Using a syringe, draw 100 mL of the transformer oil into an appropriate
container.
c. Reinstall the lid of the transformer.
d. Cap and seal the container. For containers with lids that are not Teflonlined, cover the bottle or jar with solvent-rinsed aluminum foil and cap.
e. Label the containers and place them in an ice chest.
3.2 HEALTH AND SAFETY PROTOCOLS
At all times, the sampling personnel of (___________________________) will observe all
health and safety requirements of Medical Center of Digos Cooperative, and will
follow the following protocols to avoid contact with PCBs or exposure of the fumes
of hot PCBs:

Wear clean or new disposable PCB-resistant gloves, coveralls, and safety
goggles while taking samples suspected to contain PCBs

Wear disposable shoe covers when entering areas known or suspected to be
contaminated with PCBs

Dispose of gloves, shoe coverings, and other disposable protective garments
in a plastic bag after use. Final disposition of these items should be the
same as for PCBs

Do not enter an area where there is an odor of fumes, solvents, or PCBs,
unless wearing a full-face air purifying respirator

Do not attempt to obtain samples from equipment that are in operation or
service

Leave power substations immediately when raining
To minimize the likelihood of PCB spills and health hazards during sampling, the
sampling personnel will also take special protocols as follows:

Avoid contamination of the surface of the sample container

Ensure that the cap is tightly affixed

Wipe stop cocks and other hard surfaces when sampling is already complete

3.3 SAMPLE PRESERVATION PROCEDURES
PCBs are normally stable in oil samples, but the laboratory may require sample
preservation procedures. As such, the sampling personnel will perform the
following sample preservation procedures:

Store samples to below 25°C to minimize the effects of temperature, pH, and
bacterial action

Observe the maximum holding time for samples to be analyzed for PCBs
(seven days) until extraction
3.4 QUALITY ASSURANCE/QUALITY CONTROL
To ensure that the sampling and analysis to be conducted will provide accurate
valid analytical data, QA/QC samples will also be collected and submitted to the
laboratory. For PCB sampling, a field blank, which is an empty capped container of
each type used in a sampling exercise, will serve as the QA/QC sample.
3.5 DECONTAMINATION PROCEDURES
All disposable sampling equipment and materials will be disposed of after the
sampling activities have been conducted. For all non-disposable equipment and
materials, decontamination will be required before the start of every sampling
activity and between each sampling point. In general, all sampling equipment and
materials will be cleaned, first by using soap and water, to remove oils. This will be
followed by rinsing with a polar solvent (e.g. methanol) and a non-polar solvent (e.g.
n-hexane) to remove PCBs and other contaminants, and finally, by rinsing with
distilled water.
3.6 SAMPLING DOCUMENTATION
As part of record keeping, the following information will be documented in a field
logbook, which will be retained for future reference:

Name of personnel who conducted the sampling

Time, date, and location of sampling

Type of sample

Sampling method

Reasons for obtaining the sample

Photos of the sketch of sample area and sampling layout
In addition, every sample collected will be accompanied by a Chain-of-Custody
Record, which will be initiated by the sampling personnel of (____________________).
This record will be used to trace possession of a particular sample from the point of
collection up until the release of laboratory analysis results.

4.0 PROTOCOLS FOR ANALYZING PCBS
To appropriately classify PCBs, laboratory analysis using Gas Chromatography –
Electron Capture Detector will be conducted. For this purpose, Medical Center of
Digos Cooperative will contract (_______________________________), a laboratory
registered under EMB to perform analysis of PCBs in transformer oil, waste oil, and
non-porous surface materials. Its registration details are summarized hereafter.
