1. RADIOGRAPHY PERMIT

2. The objective of Radiography Permit is ; Ensure that all the radiography jobs and other jobs involving radio-active source in refinery is properly authorised . Make the person/s doing the work fully understand/s the hazards and risks involved. Ensure that the person responsible for the operation area is fully aware of the work being done or to be done in his area . Provide a written record to show that the method of work or job safety analysis has been done and the precautions needed.

3. SCOPE The Radiography Permit shall be issued for all the routine, non-routine radiography and other jobs involving Radio-active source. Radiography permit is required in the Process, Utilities and Oil Movement areas and all other areas of refinery including buildings.

4. PROCEDURE : The Radiography is done to check the pin hole, thickness of the piping, vessels tanks etc. This is normally done by inspection section. The inspection personnel will contact the concerned Area Supervisor for issuing a Radiography Permit. The Radiography will preferably be done during meal hours or night, to minimize the exposure of the personnel to the Radiation. Radiography will normally be carried out by competent contractor’s personnel who will perform the radiography under supervision of the Inspection section (Authorized User). Radioactive sources must be stored, handled and used in accordance.

5. RESPONSIBILITIES Originating Authority is responsible for issuing the Radiography permit. The Authorized user is responsible for ensuring strict compliance with this procedure by all his subordinates and contractors. Radiography Equipment and Fire equipments required Radiation safety signs were installed Work location barricaded Dosimeter are provided Other safety equipment provided Stand by person’s presence The contractor personnel carrying out the Radiography are responsible for strict compliance with the precautions specified on the permit.

8. PRECAUTIONARY STEPS : Radiography shall take place within a controlled area, segregated by barrication , warning lights (Beacon lights) and stand by persons. The controlled area shall have the boundary barricades located so that the instantaneous dose rate at the boundary shall not exceed 6 microSv /h (0.6 mRem /h). No person should be present within the controlled area during radiographic exposure. Local shielding of sources, including collimators, should be used where possible to reduce dose rate and size of controlled area. Warning signals, audible or visible or both, should be clear.

9. Two warnings must be given, the first immediately prior to and the second during radiography operations . The radiation symbol and an appropriate instruction such as ‘No Admittance to Unauthorized Persons’, warning signs shall be in Urdu and English.
