Scope of inventory • What is the scope of PCBs Inventory ? ? • Why need IVENTORY ? ? • Basis to develop the PCBs phase out Management
Plan of Egypt : • --Compilation of an accurate list of PCBs • PCBs Identification, location, condition, service history, PCBs quantities, PCBs concentration
• Assist in ensuring integrity and safe
management of equipment containing PCBs
• --Verification of final disposal needs
Targeted Characteristics of Inventory
Accurate Dynamic Transparent
Main Steps of Inventory
•
1st Step: Prepare the Inventory • Inventory Plan • Communication with facility • Training of personnel
• Safety plan (PPE, location, hazard identification /electricity…)
• 2nd Step: Conduct the Inventory
Plan the Audit General data
•
Audit Plan (home work - prepare) • Facility information, lay out • Select the equipment/s to be Audited • Prepare sampling plan and Analysis • Logistics (sampling and analysis) • Personnel involved (ask names – positions) • Time schedule • Prepare documentation procedure • Collect maintenance historical data • Assess Hazards during the inventory
Plan the Audit In-house Audit team
•
• Case 1. In-house Audit team • Training of personnel • Explain the purpose of the inventory • Train personnel on PCBs handling and associated risks • Emphasize significance of PPE and plant safety procedures
Plan the Audit Third party Audit team
•
• Case 2. Third party Audit team
• Audit Plan • -Ask for cooperation from facility manager • • • • •
before conducting the Audit -Explain the purpose of the Audit -Plan the Audit actions -Select the areas and equipment to inspect -Obtain equipment service records, if any -Learn plant safety procedures
Selection of appliances to be Audited
•
•HOME WORK IMPORTANCE !!! Before physical / site visit Audit try to find out the Kind of appliances should be Audited!
•Transformers •Capacitors •PCBs-containing waste •PCBs discharges and contaminated soil •Hydraulic fluids •Oil-filled electrical cables •Oil filled bushes –Isolators •Other, specify
Site visit – In situ Audit – Physical Audit

Auditing Methodology 1st case
Screen
nameplate
Write down physical condition, damages leaking
Inspect records of the equipment
Write all collected information in to INVETORY FORM
Auditing Methodology 2nd case
• No
nameplate
Write down physical condition, damages leaking
Inspect records of the equipment
Write all collected information in to INVETORY FORM
Physical Audit Collect macroscopic data from in situ Audit
•
• In situ works : • Look for manufacturer's nameplate if available
• Locate other records or information about the equipment
• Apply macroscopic assumptions rules,
Physical Audit Collect macroscopic data from in situ Audit
•
• Macroscopic Assumptions for transformers: • Manufacturer's nameplate • Manufacturer • Date of manufacture • Cooling system (ONAN, LNAN..) • Dielectric oil information's • Ratio of dielectric oil weight to total weight • >0,3 may PCBs oil • <0,3 may mineral oil • Smell,

Physical Audit Collect macroscopic data of transformers /capacitors/ other electrical appliances
•
• 1.Walk around and inspect the equipment • 2. Check for leaks, spills, corrosion • Oil stains anywhere on "breaks" in tanks • Most common point for leaks is at the stopcock. (draining screw) • 3. Check damages on the equipment • 4. Take samples only from equipment not connected to any power source
Physical Audit Collect macroscopic data from in situ Audit
•
• 5. Follow always the electrician of AUDITED company • 6. Determine whether the equipment has undergone retrofitting/retrofilling. If yes, ask what they did with the waste oil/fluid? • 7. If equipment has been retrofilled, ask for service records
Some common trade names of PCBs
•
• • • • • • • •
Aroclors (PCBs mixtures from Monsanto ) Askarel: Clophen - Bayer (Germany) Diaclor - Sangamo Electric (USA) DK - Caffaro (Italy) Inerteen - Westinghouse Electric (USA) Pyralene - Prodelec (France) Santotherm - Mitsubishi (Japan)
•
We prepared a short guidance to identify PCBs and also in your handouts are more details
PCBs Inventory Access Impact to Health - Safety and the Environment
â&#x20AC;˘
Health and Safety Impact Skin contact during inspection of equipment
Environmental Impact Spills of PCBs during inspection of name plate
Requirement Use proper skin protection
Requirement Prepare proper spill response equipment
Tools to implement a dynamic PCBs data base and combat cross contamination
â&#x20AC;˘
â&#x20AC;˘-Introduce all stakeholder [producers-owners] responsibility to audit their appliances and declare/send the data to the ministry.
-Introduce for transformers the responsibility of oil treatment facilities or maintenance or scrap yards to declare all transformers entering their facility to the data base -Introduce a monitoring system to follow and evaluate set phase out time of 2025 and if necessary to take corrective actions
