Hazardous Substances Signs

Hazardous substance signs provide clear identification where chemicals, gases, biological hazards or other dangerous substances are stored, handled, transported or used. This category brings together dedicated warnings and hazard symbols for specific substances and hazard classes, helping workers, contractors and visitors recognise potential risks before entering or working within an affected area.

The range includes signs for chemical storage and handling, with products such as Warning COSHH Store, Warning Chemical Store, Warning Chemical Waste, Warning Chemical Irritants, Warning Harmful Chemicals and Dangerous Substances. There are also dedicated notices for specific materials including ammonia, chlorine, solvents, acids, caustic substances, bleach and battery acid.

Gas-related identification includes Danger Carbon Dioxide, Warning Pressurised Cylinder, Gas Cylinder Full, Gas Cylinder Empty, Warning Compressed Gas and Gas Shut Off Valve signs. These provide more specific identification where compressed or hazardous gases are present and where the status or control point of a cylinder or installation needs to be made clear.

The category also covers a broad selection of recognised hazard types and symbols, including Explosive, Corrosive, Toxic, Poison, Dangerous When Wet, Spontaneously Combustible, Flammable Gas, Flammable Liquid, Flammable Solid, Oxidising and Biohazard warnings. Dedicated radiation, harmful-fumes and oxygen warnings are also available, providing options for more specialised environments.

For specific chemical hazards, the range includes products identifying hydrochloric acid, acids generally, caustic substances, corrosive materials, chlorine, ammonia and harmful fumes. There are also warnings for hazardous waste and pesticide-related risks, allowing the message to be matched more closely to the substance or activity involved rather than relying solely on a generic hazard symbol.

These products are suitable for chemical stores, laboratories, manufacturing facilities, workshops, plant rooms, waste-handling areas, storage locations and other workplaces where hazardous substances may be present. Clear identification at doors, entrances, storage points, cupboards, equipment or affected work areas can help communicate the nature of the hazard before people approach the relevant location.

When selecting a hazardous substance sign, consider the specific material or hazard being identified, the location of the sign and whether a written warning, recognised symbol or combination of both provides the clearest message. Choosing signage that reflects the actual substance or hazard helps create a more precise and consistent visual identification system across the workplace.
