KAEFER KIPS Safety Presentation
- 1. KIPS NDT Device Radiation Safety
- 2. Presentation Breakdown • Device information & settings • Licensing & registration • Device exposure pattern • Operator exposure to date • Safety equipment • Contacts Presentation Breakdown
- 3. About the KIPS NDT Device Device Information • Portable, real time x-ray radiography device • Lightweight, quick and easy to operate • Provides live radiograph video • Primary use to screen for CUI on insulated pipes • Other uses include • Weld location detection • Insulation component reliability • Detection of water in insulation • Potential detection of asbestos insulation
- 4. Device Settings Device Settings Voltage settings: • 40 kV, 55 kV or 70 kV Current: • 0.1 mA, 0.2 mA or 0.3 mA Beam collimation: • The beam is tightly collimated towards the detector The KIPS NDT produces a highly directed low power beam of radiation towards the detector pad. Radiation exposure outside of the C-arm is relatively low.
- 5. Licensing and Registration Licensing and Registration As the KIPS NDT produces a radiation exposure, it is considered a controlled device as per state/territory radiation health guidelines. Licensing and registration requirements (for each state/territory) • Use licence • Possession licence • Device registration KAEFER and our operators are licensed to possess and use this device in South Australia by the EPA
- 6. Device Radiation Exposure Pattern Device Exposure Pattern Survey: • Radiation exposure survey conducted by Dr Kent Gregory (SA Radiation) in June 2016 • Controlled test with KIPS device set at maximum voltage and current settings Results: • Barricade to be set up at minimum two metres from test point • Maximum radiation exposure allowed at barricade is 25 uSv/hr (ARPANSA) • KAEFER normally operate a five metre barricade • Instantaneous x-ray on to x-ray off process (remove finger from trigger) if barricade is breached
- 7. Operator Radiation Exposure Monitoring Exposure Monitoring Full Time Operators, to date: • Average < 0.02 mSv/month deep dose equivalent exposure • Maximum DDE = 0.50 mSv/month • Normally work 14 days per month Part-time operators & assistants, to date: • Have not recorded a readable exposure in any month
- 8. Safety Equipment Safety Equipment Site Radiation Safety Equipment • Personal monitoring device (rad badge) • Records cumulative ionising radiation exposure • Required by all radiation workers and personal to each • Device returned monthly for exposure record reading & comparison to control badge • Chirper • Emits visual and audible signal at frequency proportional to instantaneous radiation exposure rate • Required by each operator / assistant • Radiation survey meter • Provides quantifiable readout of radiation exposure levels • Can also act as a chirper and digital rad badge. • Single survey meter required to be
- 9. Supplementary Equipment Supplementary Equipment Site Supplementary Safety Equipment • Barricade tape • To barricade so non-radiation workers are not subject to doses higher than 25 uSv/hr • Required around work space or at entry point to alert of radiation zone • Signage • To alert of danger of radiation exposure and radiography taking place • Operator to confirm requirement of signage – lower risk areas (controlled from public) may not necessitate a need for signage • Red light • To alert towards the signage or barricade tape • To be lit while radiation exposure is active • Operator to confirm requirement of lighting – lower risk areas (controlled from public) may not necessitate a need for lighting
