What Are Veterinary X‑Ray Warning Lights?

Veterinary X‑ray warning lights are control area signals placed at entry points to X‑ray rooms. These lights activate whenever the generator is in use, indicating that the area is subject to controlled radiation exposure.

Why Fail‑To‑Safe Functionality Is Vital

Fail‑to‑safe designs ensure if a warning light or system malfunctions, the X‑ray generator will be disabled. This removes the risk of accidental exposure, safeguarding both humans and animals.

Benefits of Dual‑Stage Warning Lights

Two‑stage warning lights provide a stronger visual separation between room status. The first light (usually amber) shows the room is restricted, and the second (red) signals active X‑ray use with phrases like “DO NOT ENTER”.

Portable to Integrated: X‑Ray Options for Vets

Flexible and Mobile Radiography Units

Portable models like the VET‑20 are intended for field and clinical use. Features include laser positioning, remote exposure, LCD screen, and a tough exterior — ideal for ambulatory work or small-animal clinics.

High-Frequency, Lightweight Units for Vets

Weighing approximately 13 kg, the Cubex range includes features such as digital displays, dual laser pointers, and easy pairing with digital imaging platforms. These systems are efficient and compact.

Fixed X‑Ray Units for Larger Clinics

Integrated X-ray systems like the ZooMax are suited for in-house use. Larger or mixed-animal practices may choose ceiling-mounted, telescopic systems to manage high patient volume effectively.

IRR17 Compliance for Veterinary Practices

Veterinary radiography must meet the standards of the Ionising Radiations Regulations 2017 (IRR17). Clinics are expected to provide:

• Warning lights at every access point that operate automatically and follow fail‑to‑safe design principles.


• Clearly labelled isolation switches located outside the radiation zone.


• Up-to-date radiation risk assessments, local rules, and guidance under the responsibility of a Radiation Protection Supervisor (RPS).

Best Practice Recommendations

• Choosing the right lights: Opt for LED fail‑to‑safe lights visible from a distance and compliant with IRR17. Two‑stage lights are recommended for added clarity.


• System selection: Choose portable systems like VET‑20 or Cubex for versatility. Integrated setups may better serve high-volume or equine practices.


• Installation and documentation: Collaborate with your RPS or safety advisor to install correctly, and ensure all testing and documentation meet regulatory standards.

X‑Ray Safety and Equipment Questions

What does “fail‑to‑safe” mean?

If the safety light fails, the x-ray unit disables itself automatically.

Are two-stage lights legally required?

Not mandatory, though they offer enhanced communication.

Can I use a portable X‑ray machine in both the clinic and the field?

Yes, both VET‑20 and Cubex models are multi-purpose for clinic and ambulatory care.

What is the weight of portable X‑ray units?

The VET‑20 weighs about 9.8 kg and the Cubex around 13 kg. Both are easy to carry and operate.

Do I need approval to install warning lights?

Yes, installations must follow IRR17 standards and be verified by your RPS or an authorised adviser. Proper planning and records are essential.
