Why this sign: It should be posted at entry points and around equipment that generates significant non-ionizing radiation, such as high-power radio antennas, radar arrays, or RF industrial machinery. The sign addresses the risk of thermal and biological effects from prolonged or high-intensity exposure to electromagnetic fields, helping ensure workers and visitors take appropriate precautions.

Compliance note: In Ireland, employers must provide appropriate safety signage where hazards cannot be avoided or adequately reduced by other measures, based on the workplace risk assessment, under the Safety, Health and Welfare at Work (General Application) Regulations 2007. This sign is suitable for use as part of a workplace safety-signage system where identified by that risk assessment.

Frequently Asked Questions

What does a Warning Non-Ionizing Radiation sign mean?
A Warning Non-Ionizing Radiation sign alerts people that the area or equipment nearby emits non-ionizing electromagnetic radiation, such as radio frequency or microwave energy, which may pose a health risk if safe exposure limits are exceeded.

Where should a Warning Non-Ionizing Radiation sign be displayed?
Place the sign at or near radio transmitter and antenna installations, radar facilities, or wherever the relevant action is required.

Is a Warning Non-Ionizing Radiation sign a warning sign safety sign?
Yes. It uses the yellow and black warning sign-format design. In Ireland, employers must provide appropriate safety signage where hazards cannot be avoided or adequately reduced by other measures, based on the workplace risk assessment.

What is the difference between “Warning Non-Ionizing Radiation” and “Caution Non-Ionizing Radiation”?
They communicate the same instruction. “Caution Non-Ionizing Radiation” is also commonly used for this type of sign.

Which material should I choose?
See the material guide above — Aluminium Composite for permanent/outdoor use, Correx for temporary signage, and Self-Adhesive Vinyl for direct application to smooth surfaces.

Can this sign be used outdoors?
Aluminium Composite and Self-Adhesive Vinyl are suitable for outdoor use. Correx is best suited to indoor or short-term outdoor use, as extended exposure to the elements can affect its lifespan.

What sizes are available?
Available in 100mm x 150mm, 200mm x 300mm, 400mm x 600mm, 600mm x 900mm.
