(NORMS) Naturally Occurring Radioactive Material for Supervisors course


Five (5) hours


The course designed to provide PDO and PDO contractor supervisors awareness, knowledge and understanding of NORM in the oil and gas industry, and the PDO requirements associated with it, so that the safety and health of staff and the public are not compromised, and the environment is not harmed as well as the course cover the following;

  1. SP1170 and NORM Guidelines
  2. Define NORM, fixed scales, sludge and pigging waste including basic radiation theory
  3. Health and Environmental risks – Who is at risk, how, when and why?
  4. Precautionary Principle; maintenance and well servicing activities that must include NORM monitoring using the approved meters
  5. Practical demonstration of which, when, how to use the NORM meters and their limitations
  6. Controls to implement if NORM is identified to mitigate the risk, e.g. PPE, Hygiene, Plastic wrapping of contaminated equipment
  7. Disposal of NORM contaminated equipment and sludge to the Bahja NORM Yard
  8. Relevant NORM documentation and Permit to Work
  9. Reporting NORM results e.g. EDM or Production Station Spreadsheets
  10. NORM monitoring video.
  11. Collecting a representative sample of sludge
  12. Stepping through specific activities e.g. tank cleaning (MSE.14), Well servicing (MSE.24), Pigging (MSE.15) and Maintenance activities in production stations (EMC) or outside stations such as MSV’s and flowlines (ODC)


PDO & Contractor Production Supervisors / Operators, Maintenance Coordinators/Supervisors, Pigging contractor supervisors, tank/separator cleaning contractor supervisors, Well Service (Rig/Hoist) Managers/Drillers, EMC Contractor maintenance supervisors and ODC Contractor maintenance supervisors, NORM Yard and WTF Yard Supervisors, other supervisors working with potential NORM contaminated equipment or material


  1. Provide awareness and knowledge of NORM, the hazards and risks associated with it.
  2. Provide knowledge of where NORM may deposit
  3. Introduce field instruments associated with suspected NORM
  4. Introduce the precautionary principle and actions required if NORM is identified.
