Radiography Safety HSE Training
Slide 1: Radiography Safety – HSE Training
Presented by: HSE STUDY GUIDE
Date: 25/04/2025
Good morning team!
Today’s HSE session focuses on a topic that’s extremely important, yet not always visible — Radiography Safety.
Radiography is a powerful tool for inspecting welds and structural components, but it also involves exposure to ionizing radiation, which can be dangerous if not managed correctly. So today, we’re going to learn how to work safely around radiography and how to protect ourselves and others during testing operations.
Slide 2: Training Objectives
By the end of this session, you’ll understand:
- What industrial radiography is
- The risks of radiation exposure
- Key safety precautions and safe work practices
- Roles and responsibilities during radiographic testing
- What to do in case of an emergency or exposure
Slide 3: What is Industrial Radiography?
Industrial radiography is a non-destructive testing (NDT) method used to inspect:
- Welds in pipelines, tanks, and structures
- Structural components for internal flaws or defects
It uses X-rays or gamma rays to capture internal images without cutting or destroying the material — much like a medical X-ray, but much more powerful.
Slide 4: Types of Radiation Sources
Radiography typically uses two types of radiation sources:
- X-Ray Machines: Electrically powered and can be turned on/off
- Gamma Ray Sources: Use radioactive isotopes like Iridium-192 or Cobalt-60, which emit radiation continuously and must be shielded
Both can be harmful if not handled properly.
Slide 5: Hazards of Radiation Exposure
Radiation exposure is invisible, silent, and odorless — but the effects are real.
Short-term exposure can cause:
- Skin burns
- Nausea and fatigue
- Hair loss
Long-term or repeated exposure can lead to:
- Cancer
- DNA damage
- Internal organ damage
- Death in extreme cases
And remember — there’s no “safe” dose of radiation, only safe exposure limits.
Slide 6: How Exposure Happens
You could be exposed to radiation if:
- You enter the radiography work zone without authorization
- Shielding is missing or damaged
- The source is not properly secured
- Warning signs and barriers are ignored
- Communication with the radiographer fails
Awareness is the first step in prevention.
Slide 7: Radiography Safety Zones
Radiographic testing areas are divided into safety zones:
- Controlled Area (High Radiation): Only authorized radiographers may enter
- Restricted Area: Barriers and warning signs are posted, entry is limited
- Safe Zone: Outside the exposure area, safe for general personnel
Never cross barriers or signs without permission.
Slide 8: Key Safety Signs You’ll See
Watch for these signs:
- Radiation Symbol (Trefoil) – indicates radioactive materials or radiation
- “Controlled Area – No Entry”
- “Radiography in Progress”
- Warning lights or beacons during active X-ray or gamma ray use
These are not just for show — they’re your line of defense.
Slide 9: Roles and Responsibilities
Let’s talk about who does what:
- Radiographers: Certified professionals who operate radiation equipment
- HSE Officers: Ensure safety procedures are followed
- Supervisors: Control access and confirm clearances
- All Workers: Stay out of restricted areas, report unsafe conditions
Everyone has a part to play in keeping the site safe.
Slide 10: Before Radiography Begins
Before any test starts:
- Permit to Work must be approved
- Barricades and signage must be in place
- Radiation survey meter should be tested
- Clear the area of unauthorized personnel
- Toolbox talk should be conducted
If any of this is missing — the test must not begin.
Slide 11: During the Radiographic Test
During testing:
- Never enter the barricaded area
- Respect all posted signs and flashing lights
- Maintain constant communication with the radiographer
- Stay in the safe zone at all times
- Use dosimeters if you’re in the vicinity regularly
Don’t assume it’s safe — ask and confirm.
Slide 12: After the Test Ends
After completion:
- Wait for the radiographer to declare the area safe and clear
- Do not remove signs or barricades unless authorized
- If there’s any suspicion of exposure, report immediately
- Ensure equipment is safely stored and locked
No one re-enters until full clearance is given.
Slide 13: Emergency Situations
In case of suspected exposure or incident:
- Evacuate the area immediately
- Inform the radiographer and HSE officer
- Do not attempt to retrieve a lost source
- Await emergency team instructions
- Get medical evaluation if required
Quick response can prevent serious harm.
Slide 14: Real-Life Case Study
Let me share a real incident…
A worker entered a radiography area thinking the test was finished. No signs were posted, and communication failed. He suffered radiation burns to his torso and required months of treatment.
Lesson learned: communication, signage, and discipline are critical. Never assume — always confirm.
Slide 15: Key Takeaways
To wrap up:
- Radiation is invisible but dangerous
- Always respect warning signs and barriers
- Never enter a test area without clearance
- Ensure radiography work is properly coordinated
- Report any suspicious activity or exposure immediately
Safety during radiography is about team awareness, training, and trust.
Slide 16: Questions or Experience Sharing
Any questions about radiography work or safety?
Have you ever seen unsafe practices or a near-miss? Let’s share and learn together.
Slide 17: Thank You
Thank you all for your attention and commitment to safety.
Let’s always stay sharp when working around radiography — because it’s not just about inspections… it’s about protecting life and health.
