Wall Mounted X Ray Warning Lights
Raybloc’s Wall Mounted X Ray Warning Lights offer a dependable solution for signalling active radiation exposure in controlled X-ray areas. Engineered for high visibility and easy installation, these lights provide essential visual alerts, notifying personnel when X-ray equipment is active.
Featuring a white powder-coated aluminium frame, Raybloc’s wall-mounted lights are designed to withstand the rigorous demands of medical and research settings, complementing our radiation shielding solutions seamlessly. Dimensions are 50mm (deep) x 345mm (width) x 185mm (height).
X-Ray in Use Sign for Radiation Safety
Effective “X-ray in use” signage is essential for maintaining safe environments around X-ray rooms. Raybloc’s wall mounted warning lights signal to staff when an area is live with radiation, reducing the risk of accidental exposure.
These lights incorporate a unique two-stage functionality that is integral to maintaining clarity in controlled areas: a steady yellow signal for readiness and a red alert for active exposure, fulfilling Radiation Protection Advisor requirements.
Importance of X-Ray Warning Lights in X-Ray Room Safety
Immediate visual alerts provided by X-ray warning lights are critical for safety in controlled areas. Once wired by an electrician, Raybloc’s warning lights activate automatically once the power supply to the X-ray unit is connected, notifying personnel of exposure and preventing unauthorised entry.
The two-stage functionality of the warning lights further enhances safety protocols by signalling precisely when the area is prepared for radiation and when exposure is active, ensuring a safe controlled-area environment in which Raybloc’s lead-lined products work in conjunction to establish a secure environment.
Two-Stage Functionality of Raybloc Warning Lights
Raybloc’s warning lights are built with a two-stage system to offer clear, unambiguous signals in radiation-controlled areas. The first stage, a yellow text display that reads “CONTROLLED AREA X-RAYS” remains illuminated as long as the power is supplied to the X-ray equipment or radiation source, signalling readiness. Once the X-ray machine begins to emit radiation, the second stage activates a red “DO NOT ENTER” sign, providing an explicit warning to avoid entry.
Both our wall-mounted and flush-mounted variations feature this two-stage functionality, ensuring clear communication of exposure status. When not illuminated, the text remains barely visible, eliminating any confusion about whether it is safe to enter the area, as specified by Medical Physicists and Radiation Protection Advisors.
Benefits of Wall-Mounted Warning Lights
Raybloc’s wall-mounted X-ray warning lights are crafted with high standards of durability and visibility, making them ideal for high-traffic medical environments. Their LED flat panel disperses light evenly, ensuring consistent visibility across a range of lighting conditions.
Although Raybloc’s flush-mounted door warning lights offer a more integrated, hygienic design with primary fire testing for FD30 and FD60 doors, our wall-mounted lights remain a reliable choice, providing effective safety alerts in settings where flush mounting may not be feasible.
Features of X-Ray Warning Signs
Raybloc’s wall-mounted X-ray warning lights are designed to meet the rigorous demands of radiation-controlled areas, including:
- Two-stage illumination for clear “CONTROLLED AREA X-RAYS” and “DO NOT ENTER” alerts.
- White powder-coated aluminium frame for long-lasting durability, only 50mm deep.
- Flush-fitting LED flat panel that illuminates with bright, unambiguous signals.
- Multiple conduit entry points (top or rear), with flexible installation options.
- Four-point mounting system for secure attachment to suitable surfaces.
Additionally, our warning lights come with a fused PCB and NTC thermistor for power protection. Installation requires a qualified electrician to ensure proper wiring and compliance with electrical safety standards.
Installation of X-Ray Warning Signage
Raybloc’s wall-mounted warning lights are designed for straightforward installation, with four fixing points (300mm x 133mm) to ensure stability on any suitable surface. Power cables from the X-ray equipment should be run through 20mm conduit glands, either from the top or rear, and connected to the warning light box.
The final position of each light is determined by a Radiation Protection Advisor (RPA) to optimise visibility and meet safety standards. Before any maintenance, the mains supply should be disconnected to protect the power unit and avoid warranty invalidation.

Medical Safety Standards and Certifications of X-Ray LED Warning Lights
Raybloc’s wall-mounted warning lights adhere to stringent safety standards required for radiation shielding environments. The two-stage illumination function is specifically designed to meet RPA requirements, ensuring unambiguous signals for both readiness and active radiation exposure. These lights integrate seamlessly into controlled areas without compromising shielding or compliance.
Eco-Friendly Features
In line with Raybloc’s commitment to sustainability, these wall-mounted warning lights utilise energy-efficient LED technology that conserves power while providing bright, effective illumination.
With their long-lasting LED panels, our warning lights reduce operational costs and contribute to a more sustainable healthcare environment.
Why Choose Raybloc For Wall Mounted X-Ray Warning Lights?
Raybloc’s expertise in radiation shielding solutions has positioned us as a trusted name in healthcare safety. Our wall-mounted X-ray warning lights are designed to enhance controlled area safety through clear, reliable alerts.
For facilities seeking a more integrated design, Raybloc’s flush-mounted door warning lights, developed in 2013, offer superior visibility, fire-tested compatibility with FD30 and FD60 doors, and a seamless look.
Whether you choose wall-mounted or flush-mounted warning lights, Raybloc provides dependable solutions tailored to the highest safety standards in radiation-controlled environments.
FAQs
What is a warning light in radiology?
A warning light in radiology signals when X-ray equipment is active from the entrances into the controlled area, notifying personnel and visitors to avoid entering the room to prevent unintended radiation exposure.
What is the warning light outside the X-ray room?
The warning light outside an X-ray room indicates when radiation equipment is in use. Typically positioned at the room entrance, it provides a visual alert to maintain safe distances.
What is a controlled area?
A controlled area is a designated space within an X-ray facility where radiation levels are carefully managed. Entry is restricted when X-ray equipment is active, and warning lights help enforce safe access in line with radiation safety protocols.
How does a wall-mounted X-ray warning light work?
A wall-mounted X-ray warning light connects to the power supply of the X-ray unit. When the equipment is powered on, a yellow “CONTROLLED AREA X-RAYS” warning light activates, and once X-rays are being emitted, the light switches to a red “DO NOT ENTER” warning, signalling to personnel and visitors to avoid entry.
What is the difference between a flush-mounted and wall-mounted X-ray warning light?
Raybloc’s flush-mounted warning lights are integrated into the door leaf, making them more hygienic and better positioned for visibility, particularly in high-traffic areas. Wall-mounted warning lights are attached to the wall and provide similar two-stage functionality but are easier to install when a new Raybloc Doorset is not required.
Where should a wall-mounted X-ray warning light be installed?
The placement of a wall-mounted X-ray warning light should be determined by a Radiation Protection Advisor to ensure optimal visibility. Typically, it is positioned near entrances to controlled areas, so staff and visitors can see it easily before entering an X-ray room.
Are Raybloc wall-mounted X-ray warning lights compliant with fire safety regulations?
While wall-mounted lights are not flush with fire-rated doors, Raybloc’s flush mounted warning lights are fire-tested for FD30 and FD60 doors, meeting fire safety standards and providing a seamless design that integrates with fire-rated doorsets.
