Foreword
This document (CEN/TR 15522-1:2006) has been prepared by CEN/BT/TF 120 “Oil spill identification”,
the secretariat of which is held by SN.
Introduction
Where an oil pollution incident has occurred, samples should be collected from both the spill and,
wherever possible, the potential source of the pollutant, e.g. ship, shore tank, pipeline or road vehicle,
in order to assist in the identification or confirmation of the source of the spill. The aim of this
document is to give guidance on the best current practice for taking such samples.
This document does not contain details relating to all types of spill situation, but should only be
regarded as general guidelines. However, by following these guidelines it should be possible to collect
and provide legally valid samples that can be used in the process of identifying or confirming the
source of the spill.
The issues addressed only cover the mechanics of sample collection. The command and control that
may be put in place during incident response, the authorities who may request sample collection and
the individuals who have the authority to collect samples, will vary from country to country and as a
consequence these issues are not addressed.
1 Scope
This document provides guidance on taking and handling samples that are collected as part of an
investigation into the likely source of a crude oil or petroleum product spill into a marine or aquatic
environment. Guidance is given on taking samples from both the spill and its potential source.
If samples are to be used in connection with legal proceedings, this document should be read in
conjunction with any documents issued by the regulatory authorities in the country and location where
the spill has occurred.
Taking samples may involve hazardous materials, operations and equipment. This document is not
intended to address all the safety and health aspects associated with the guidance given. It is the
responsibility of the user to consult and establish appropriate safety and health practices and
determine the applicability of regulatory limitations prior to use.
For the sake of clarity the word ‘oil’ is used throughout this document to mean either crude oil, a
petroleum product or mixtures of such.
2 Normative references
The following referenced documents are indispensable for the application of this European Standard.
For dated references, only the edition cited applies. For undated references, the latest edition of the
referenced document (including any amendments) applies.
EN ISO 3170, Petroleum liquids - Manual Sampling (ISO 3170:2004)
3 Principle
Samples form an important aspect of any investigation and care should be taken to ensure that they
are as representative of both the spill and the potential source as possible. The samples shall be
taken and placed in containers that will enable the samples to be transported safely and will retain the
samples integrity over the period of time required to transport the samples to the laboratory for
analysis and storage prior to analysis. They shall be clearly, unambiguously and uniquely labelled and
sealed so that they cannot be opened without breaking the seal.
When investigating a spill, samples are usually taken from:
The water surface (sea, river or lake);
shoreline or banks (sand, shingle, rocks and oiled animals and vegetation);
marine or river vessel’s cargo tanks, fuel tanks, waste oil tanks, slop tanks, ballast tanks and
bilges;
land tanks and pipelines.
All spills and all potential sources of spills should be sampled. It is important to take samples from
both the spill and the source even on such occasions where it seems quite clear from where the spill
originates.
Sampling procedures, which are connected to liability investigations, shall be performed with great
care and accuracy and every action shall be taken to prevent a decrease in the samples' value as
evidence.
If a spill has scattered and only thin sheens remain on the water surface, every possible effort should
be made to take a sample of the spill material. No sample volume is too small and samples that
seemingly consist of pure water or sample pads that do not show any traces of oil can, when
analysed, provide useful data.
If any part of the spill differs in any respect from other parts, extra samples shall be taken to check if
more than one spill has occurred in the area.
If the spill response operation continues for more than one day, samples should be taken every day to
make it possible to determine the degree of weathering of the oil, as well as possible contamination
by other oils.
If an oil sample is suspected to be contaminated with material already in the water, if possible also
take samples of the water plus the ‘contaminant’. Waters in harbours and estuaries may contain
traces of various petroleum products and when spills in such waters are sampled it is therefore
important to provide the laboratory with blank samples of the water.
Sampling equipment shall be handled and stored in such a manner that its use cannot contaminate
the samples being taken.
Samples shall be handled as legal evidence and shall be kept in a chain of custody until identification
and possible legal procedure has been completed.
NOTE Identity per se requires all measurable data to be the same. This definition is practically and
technically impossible to fulfill, and instead the definition of identity is rephrased in operational terms: two
samples are identical if no differences in the analysed GC-FID and GC-MS data are present that cannot be
explained by weathering. The task of looking for differences in chemical composition instead of proving similarity
is conceptually more logical and easier to comply with. According to this, only distinct differences between
samples can be proved whereas identity per se cannot. Therefore, only when no differences between samples
are observed can identity be concluded as being beyond reasonable doubt.
4 Precautions and avoidance of contamination of samples during collection
4.1 General
It is critical to take precautions in order to prevent contaminating the samples with traces of other oils
during collection. Disposable nitrile gloves should be used and as far as possible, the sampling
equipment should be disposable. If the equipment is to be reused great care needs to be taken to
ensure that it is thoroughly cleaned and stored in a clean condition prior to further use.
4.2 Potential sources of contamination
Avoiding contamination of the samples during sampling is essential. All the following possible sources
of contamination should be considered and the appropriate control applied if necessary. These are:
residue of earlier samples remaining on sampling containers, funnels, scoops, spatulas and
...
