Hazardous Substance Diamonds by Caledonia Signs - Trade Only Supplier
Hazardous Substance Diamonds are vital safety labels designed to quickly convey the risks associated with dangerous chemicals and materials through a standardised colour-coded and numbered system. These diamonds, often based on the NFPA (National Fire Protection Association) or similar standards, use four distinct coloured sections—blue for health hazards, red for flammability, yellow for reactivity, and white for special precautions—to provide essential information at a glance. This clear visual communication helps workers, emergency responders, and anyone handling these substances understand the level of risk involved, enabling them to take appropriate precautions.
The importance of Hazardous Substance Diamonds lies in their ability to improve workplace safety by promoting awareness and preventing accidents. By displaying the degree of hazard in each category, these labels help ensure that employees know when to use protective equipment, handle materials with care, and store substances correctly. In emergencies, such as fires or chemical spills, the diamonds provide critical information to first responders, guiding their actions to contain hazards safely and efficiently, ultimately reducing the risk of injury or environmental damage.
Moreover, Hazardous Substance Diamonds play a key role in regulatory compliance. Many health and safety regulations require clear identification of hazardous materials to ensure safe handling, transport, and storage. Proper use of these diamonds demonstrates a company’s commitment to meeting legal obligations, avoiding fines, and protecting workers and the public. It also supports effective communication across different departments, contractors, and external agencies by providing a universal language for hazard identification.
Finally, the consistent use of Hazardous Substance Diamonds helps foster a safety-conscious culture within organisations. These signs serve as constant reminders of potential dangers, encouraging employees to stay vigilant and adhere to safety protocols. By making hazard information easily accessible and understandable, the diamonds contribute to reducing workplace accidents, protecting health, and maintaining a secure working environment for everyone involved.
The carriage of dangerous goods by road, rail, inland waterway, sea and air is regulated internationally by European agreements, directives and regulations, and parallel legislation in the UK. Dangerous goods are assigned to different classes depending on their hazard. The person or business shipping the goods is responsible for classifying, marking and packaging the dangerous goods. ADR sets out the requirements for the classification, packaging and certification of dangerous goods being transported by road.
As well as the requirements specific to their transportation, suppliers of dangerous goods are required by law to label their products and packaged chemicals with hazard symbols and Safety advice. Recognised "GHS symbols" have been developed so that people handling hazardous goods know the nature of the hazard they present.
Below you can find a range of hazard warning diamonds which allow dangerous goods to be marked and identified during transportation and storage in line with ADR, IATA and IMDG regulations.

Why get safety signs printed by Caledonia Signs?
1. Regulatory Compliance One of the primary reasons to have safety signs professionally printed is to ensure compliance with UK laws. The Health and Safety (Safety Signs and Signals) Regulations 1996 require that specific safety signs be used in workplaces to prevent accidents and injuries. Caledonia Signs understand these requirements and ensure your signs meet legal standards, including adherence to the BS EN ISO 7010 format for safety symbols. Adhering to the BS EN ISO 7010 format is crucial because it ensures safety signs are universally recognised and understood. The standard uses clearly defined symbols that have been tested for visibility and comprehension, making them effective even in high-stress situations or for individuals who do not speak the local language. This helps prevent accidents by enabling quick and correct responses to potential hazards. Many "pop up printers" don't fully understand the importance of ISO 7010. From a legal standpoint, compliance with ISO 7...>>> READ MORE >>>
