Guidelines for the inventory control, management, decontamination and/or disposal of electrical equipment and insulating liquids containing PCBs
The scope of this Technical report is to provide guidance for the activities of inventory, control, management, decontamination and/or disposal of equipment and containers with insulating liquid containing PCBs, in compliance with the Council Directives (96/59/EC), using Best Available Techniques - BAT - (96/61/EC), Commission Decision (2001/68/EC), Stockholm Convention on Persistent Organic Pollutants (POPs) and/or with appropriate national or local legislation. This Technical report is addressed, in particular, toward the Life Cycle Management (LCM) of insulating liquids and it has been developed in accordance with the following objectives: a) reduction of risks for workers, public health and the environment, arising from human error, malfunction, or failures of the equipment that could cause fires or spillage of hazardous and Persistent Organic Pollutants (POPS)s; b) implementation of the “Best Available Techniques” (BAT),”Best Environmental Practices”(BEP)and methodologies available for safety, whilst taking into account the surroundings and the criteria of self-sufficiency and functional recovery; c) technical feasibility of the activities within the prescribed time schedules, taking into account current legislation and economic feasibility. NOTE 1 For those CENELEC countries in which the European Directives do not apply, this Technical report has an informative purpose only. Different limits from those given in the present Technical report are required in some countries. NOTE 2 For those countries outside of European Community the Stockholm Convention on Persistent Organic Pollutants (POPs) should be applied. NOTE 3 When reading this Technical report, reference should also be made to Annex C of EN 50195 and Annex B of EN 50225, because in some EU countries (i.e. France, Italy, Poland, Spain, etc.) there are other mandatory requirements.
Smernice za obvladovanje zalog, upravljanje, dekontaminacijo oziroma odstranjevanje električne opreme in izolacijskih tekočin, ki vsebujejo PCB
Namen tega tehničnega poročila je zagotavljanje vodila za obvladovanje zalog, upravljanje, dekontaminacijo oziroma odstranjevanje opreme in vsebnikov z izolacijskimi tekočinami, ki vsebujejo PCB, v skladu z direktivo Sveta (96/59/ES), z uporabo najboljših razpoložljivih tehnik - BAT – (96/61/ES), odločbo Komisije (2001/68/ES), Stockholmsko konvencijo o obstojnih organskih onesnaževalcih (POP) in/ali ustrezno nacionalno ali lokalno zakonodajo. To tehnično poročilo obravnava predvsem upravljanje življenjskega cikla (LCM) izolacijskih tekočin in je bil pripravljen v skladu z naslednjimi cilji:
a) zmanjševanje tveganja za delavce, javno zdravje in okolje, do katerega prihaja zaradi človeških napak, nepravilnega delovanja ali okvar opreme, ki bi lahko povzročili požare ali razlitje nevarnih in obstojnih organskih onesnaževalcev (POP);
b) izvajanje »najboljših razpoložljivih tehnik« (BAT), »najboljših okoljskih praks« (BEP) in metodologij, ki so na voljo za varnost, ob upoštevanju okolice in meril samozadostnosti ter funkcionalne obnove;
c) tehnična izvedljivost dejavnosti v predpisanem časovnem okviru, ob upoštevanju veljavne zakonodaje in ekonomske izvedljivosti.
OPOMBA 1: Za tiste države CENELEC, v katerih evropske direktive ne veljajo, je to tehnično poročilo le informativnega pomena. V nekaterih državah so zahtevane meje, ki se razlikujejo od mej, navedenih v tem tehničnem poročilu.
OPOMBA 2: Za države zunaj Evropske skupnosti velja Stockholmska konvencija o obstojnih organskih onesnaževalcih (POP).
OPOMBA 3: Ob branju tega tehničnega poročila se je treba sklicevati tudi na Dodatek C EN 50195 in Dodatek B EN 50225, ker so v nekaterih državah EU (tj. v Franciji, Italiji, na Poljskem, v Španiji, itd.) veljajo druge obvezne zahteve.

Introduction
Insulating liquids with PCBs bases (Askarels) or contaminated by PCBs that may still be present
in electrical equipment in the generation, transmission, distribution and use of electric energy.
Polychlorinated biphenyls (PCBs) are a mixture of 209 possible congeners (as defined by
EN 61619). Such compounds of a synthetic origin, have been produced and used in various
commercial mixtures at an international level since 1930 (see Annex A). The chemical stability
and relative non-flammable nature of PCBs was the main reason for their use by the
electrotechnical industry.
The same functional features of these substances created environmental problems: PCBs are,
in fact, classified as hazardous and persistent organic pollutants (POPs) in the environment,
bio-accumulable along the food chain.
It is recognised that oil-filled electrical equipment may have been contaminated by PCBs either
during manufacture or maintenance operations using oils which have been contaminated with
PCBs.
Insulating liquids and equipment containing insulating liquids are classified, respectively, “PCBs”
and “Equipment containing PCBs” when the total concentration of polychlorinated biphenyls
(209 possible congeners) and correlated compounds PCTs (polychlorinated terphenyls-
8 557 possible congeners) and PCBTs (polychlorinated benzyltoluenes-thousands of possible
congeners) present in the insulating liquids exceeds the limits prescribed by current legislation
for the single environmental matrices and/or applications (equipment and insulating liquids in
operation, waste, used oils, fuel oils, etc.).
During their operational life cycle, such equipment and insulating liquids degrade, and may
degrade faster if not properly managed and maintained, inducing failures that could cause
incidents having a significant environmental impact, that can be correlated to the specific site
conditions. In accordance with Directive 96/59/EC, during their service life, equipment
containing PCBs should, under certain conditions, be subject to measures capable of
preventing and/or mitigating degradation processes and the spillage of PCBs, to ensure the
protection of workers, public health and the environment, as well as complying with the
prescriptions of the Stockholm Convention on Persistent Organic Pollutants (POPs) entered into
force on 17 May 2004.
Since the 1980’s, PCBs have been subject to prohibitions and limitations for the marketing and
use: the recent Council Directives and Commission Decisions introduced new obligations for the
inventory, control, management, decontamination and/or disposal of electrical equipment and
insulating liquid containing PCBs.
1 Scope
The scope of this Technical report is to provide guidance for the activities of inventory, control,
management, decontamination and/or disposal of equipment and containers with insulating
liquid containing PCBs, in compliance with the Council Directives (96/59/EC), using Best
Available Techniques - BAT - (96/61/EC), Commission Decision (2001/68/EC), Stockholm
Convention on Persistent Organic Pollutants (POPs) and/or with appropriate national or local
legislation.
This Technical report is addressed, in particular, toward the Life Cycle Management (LCM) of
insulating liquids and it has been developed in accordance with the following objectives:
a) reduction of risks for workers, public health and the environment, arising from human
error, malfunction, or failures of the equipment that could cause fires or spillage of
hazardous and Persistent Organic Pollutants (POPS)s;
b) implementation of the “Best Available Techniques” (BAT),”Best Environmental
Practices”(BEP)and methodologies available for safety, whilst taking into account the
surroundings and the criteria of self-sufficiency and functional recovery;
c) technical feasibility of the activities within the prescribed time schedules, taking into
account current legislation and economic feasibility.
NOTE 1 For those CENELEC countries in which the European Directives do not apply, this Technical report has
an informative purpose only. Different limits from those given in the present Technical report are required in some
countries.
NOTE 2 For those countries outside of European Community the Stockholm Convention on Persistent Organic
Pollutants (POPs) should be applied.
NOTE 3 When reading this Technical report, reference should also be made to Annex C of EN 50195 and Annex
B of EN 50225, because in some EU countries (i.e. France, Italy, Poland, Spain, etc.) there are other mandatory
requirements.
