Black / White Diamond - Safety Signs by Caledonia Signs

The Black / White Diamond GHS sign is typically used to indicate the presence of hazardous materials that are non-flammable gases or other specific hazards that do not fall under the typical coloured hazard categories like flammability or toxicity. Often, these signs are used for substances such as oxidisers, corrosives, or environmentally hazardous materials depending on specific regulations.

This sign should be placed on chemical containers, storage areas, transport vehicles, and workspaces where such hazardous substances are present. Common settings include laboratories, manufacturing plants, warehouses, and shipping facilities handling chemicals that require clear hazard identification for safety.

The purpose of the Black / White Diamond is to provide clear and immediate recognition of the type of hazard involved, ensuring that workers, transporters, and emergency responders can take appropriate safety precautions. It helps prevent accidents by communicating risks effectively and supporting proper handling and storage procedures.

Using the Black / White Diamond GHS sign enhances workplace safety, promotes regulatory compliance, and ensures that all individuals interacting with hazardous materials are informed of potential dangers, even when the hazard is less visually obvious than with other GHS colours.

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