Description
ADR 3 Flammable liquids label — basis for use
The ADR 3 Flammable liquids 100 × 100 mm label is intended for marking packages containing dangerous goods classified under ADR class 3. Class 3 covers flammable liquids, meaning liquid substances and liquid mixtures which, due to their properties, may pose a fire hazard during transport, handling, storage or in the event of package damage.
The ADR 3 Flammable liquids marking is used when the goods classification, UN number, safety data sheet, transport documentation and packing instruction indicate the need to use a class 3 hazard label. This group may include selected solvents, paints, varnishes, adhesives, resins, fuels, alcohols, chemical products, technical preparations and other liquid products classified as flammable liquids.
Flammable liquids require proper marking because they may form flammable vapours, ignite from ignition sources and increase the risk of fire if the package leaks. The hazard may occur not only during transport, but also during storage, order picking, handling, loading and unloading.
The ADR 3 label is not a standalone confirmation that goods are accepted for transport. Its use should result from correct goods classification and complete transport documentation. Before use, make sure that the substance, mixture or product actually requires ADR class 3 marking and that the selected label matches the requirements for the specific shipment.
In practice, the ADR 3 Flammable liquids marking may be used when preparing shipments containing canisters, bottles, cans, buckets, containers, outer cartons, pallets or overpacks with liquid products that have flammable properties. The use of the label should always result from the classification of the specific product, UN number and transport documents, not only from the trade name of the goods.
The class 3 hazard label provides important information for people involved in transport. It helps warehouse staff, carriers, drivers, loading and unloading personnel, inspection authorities and emergency responders identify the type of hazard.
The choice of marking should always be checked against current ADR regulations, goods classification, UN number, safety data sheet, packing instruction, transport documentation, carrier requirements and internal company procedures. In case of doubt, consultation with an ADR dangerous goods adviser or a person responsible for dangerous goods transport is recommended.
Where and how to use the ADR 3 Flammable liquids label 100 × 100 mm
The ADR 3 Flammable liquids 100 × 100 mm label should be used on packages containing class 3 dangerous goods that require hazard label marking. It can be applied to cartons, individual packages, outer packages, containers, cans, canisters, buckets, crates, pallets, overpacks and other units prepared for transport.
The square 100 × 100 mm format corresponds to the typical format used for ADR labels on packages. The shape makes it convenient to apply the marking to a flat packaging surface, next to the UN number, transport documents, additional markings or other required hazard labels.
The label should be applied in a clearly visible place on the outside of the package. It should not be covered by packing tape, stretch film, waybill, courier label, carton corner, securing strap or another marking. The marking should remain legible from the moment the shipment is prepared until transport is completed.
Before application, the packaging surface should be clean, dry, free from grease and as smooth as possible. This is particularly important for coated cartons, film packaging, plastic containers, cans, canisters and surfaces exposed to dust, moisture, grease or product residues.
For overpacks and outer packages, make sure that the required markings remain visible from the outside. If ADR labels on inner packages are covered by an outer carton, stretch film, crate or pallet, the markings should be repeated on the outside of the overpack according to the requirements for the specific shipment.
For flammable liquids, readability of the marking is especially important when transport units may be inspected, handled, sorted or temporarily stored. The marking should allow quick recognition that the shipment contains a flammable liquid and requires appropriate handling, protection from ignition sources and procedures suitable for class 3 dangerous goods.
Before shipment, it is worth checking:
- whether the goods have been correctly classified under ADR class 3,
- whether the ADR 3 label meets the requirements for the specific UN number,
- whether the packaging, container, can, canister or bucket used meets the requirements for the specific product,
- whether the label has been applied to a visible part of the package,
- whether the marking has not been covered by film, tape, documents or other labels,
- whether additional labels, UN numbers, LQ marks, orientation arrows, “OVERPACK” marking or other transport markings are required,
- whether the marking is consistent with the transport documentation,
- whether carrier requirements are consistent with the selected marking method.
The label is suitable for production companies, warehouses, logistics centres, shipping departments, technical wholesalers, chemical plants, paint shops, companies operating in the paint, varnish, adhesive, solvent, fuel, cosmetics and technical chemicals sectors, as well as businesses preparing class 3 dangerous goods for domestic and international transport.
Quality of Print&Stick ADR 3 Flammable liquids labels
Print&Stick ADR 3 Flammable liquids 100 × 100 mm labels have been designed for clear and repeatable marking of packages containing dangerous goods. The square shape and 100 × 100 mm format make the label easy to apply to different packaging types and help maintain a consistent shipment marking system.
The labels are made from self-adhesive paper, allowing quick application without additional glue, tape or holders. The self-adhesive format works well in daily warehouse operations, at packing stations and when preparing larger quantities of shipments in series.
The durable acrylic adhesive provides good adhesion to typical packaging surfaces such as cardboard, paper, board, outer packages, containers, cans, canisters and selected plastic surfaces. Good adhesion helps reduce the risk of the label peeling off during storage, order picking, handling, sorting and transport.
The print is protected with UV varnish, which helps protect the graphics and label content against factors encountered during everyday logistics handling. This keeps the marking readable and visually neat during packing, storage and transport.
The product is supplied on a roll containing 500 labels. This roll format supports convenient storage, fast peeling and serial application. It works well in warehouses, shipping departments, production companies, logistics centres and businesses that regularly prepare dangerous goods for transport.
Repeatable production helps maintain a consistent appearance of successive label batches, stable format, readable print and neat package marking. For companies working according to fixed logistics procedures, this means greater consistency of marking and easier organisation of the packing process.
Print&Stick labels are manufactured in Europe. We provide after-sales support and the possibility of regular deliveries for companies that use ADR labels in packing and shipping processes on an ongoing basis.
Label production is carried out in accordance with quality and environmental management standards consistent with ISO 9001 and ISO 14001. For users, this means stable product quality, repeatable workmanship and markings suitable for regular storage, packing and transport processes.
