Radioactive III Diamond - Safety Signs by Caledonia Signs

The Radioactive III Diamond GHS sign is used to identify packages or areas containing high-level radioactive materials that emit higher radiation levels compared to Categories I and II. This label, known as Category III "Yellow III, signals a significant radiation hazard requiring strict controls during handling, transport, and storage.

This sign should be displayed on transport containers, storage units, and restricted zones in facilities such as nuclear power plants, radiopharmaceutical manufacturing, research laboratories, and industrial sites that work with or store highly radioactive substances. It is also crucial during the transportation of radioactive materials via road, rail, or air.

The primary purpose of this sign is to warn workers, emergency responders, and the public about the presence of dangerous radiation levels, prompting the use of specialised protective equipment, controlled access, and adherence to strict safety protocols. It ensures that all involved understand the risks and take necessary precautions to prevent radiation exposure.

Using the Radioactive III Diamond GHS sign supports regulatory compliance, safeguards human health, and prevents contamination or accidental exposure. Its clear, standardised warning helps maintain a safe environment when dealing with highly radioactive materials.

UN regulations (including ADR, IATA and IMDG) stipulate that all dangerous goods must be clearly identified.
