Understand IRR17 requirements, fail-to-safe systems, and what your practice must do to remain compliant.
If you operate X-ray equipment in a veterinary, dental, or medical setting, you must comply with the Ionising Radiations Regulations 2017 (IRR17). These regulations are designed to ensure that radiation exposure is controlled and clearly communicated.
Key requirement:
Controlled areas must have clear warning systems, including illuminated warning lights, to indicate when radiation is being used.
Yes. IRR17 requires that anyone entering a controlled area must be clearly warned when radiation is in use. In practice, this means installing a visible warning light outside the room.
The warning must be automatic and reliable — it cannot depend on manual switching or human action.
A fail-to-safe system ensures that if the warning light fails, the X-ray equipment cannot operate. This prevents unsafe conditions where radiation could be emitted without warning.
Fail-to-safe behaviour is widely expected during inspections and best-practice compliance.
Systems should automatically prevent operation if safety components are not functioning.
Non-compliance can result in enforcement action, including improvement notices or restrictions on equipment use until safety requirements are met.
Our fail-to-safe X-ray warning lights are designed specifically to meet UK IRR17 expectations.
