Flammable Placards - Page 2

Flammable placards are available in the standard DOT-required 10.75 inch diamond size, mandatory for vehicles and freight containers transporting hazardous materials under 49 CFR Part 172. Reduced-size labels are also available for packages and inner containers. Our flammable hazmat placards are available in all required sizes, and our flip-file placard system accommodates the standard 10.75 inch format for easy legend changes between runs.

Adhesive vinyl flammable placards are not designed for reuse since the permanent adhesive cannot be cleanly removed and reapplied. However, vinyl legends used in a placard holder system are effectively reusable because they slide in and out of the frame rather than bonding directly to the vehicle surface. Our flip-file placard system allows fast legend changes between hazmat classes, while our full range of flammable hazmat placards covers both single-use and permanent vehicle installation needs.

Tagboard is the right choice for occasional or single-trip flammable shipments where a disposable, low-cost placard meets your DOT requirements. Self-adhesive vinyl is better for carriers who transport flammable materials regularly and need a placard that withstands weather, road vibration, and extended outdoor exposure across multiple trips. For maximum flexibility across multiple hazmat classes, our flip-file placard system lets you swap legends in seconds. Browse all options in our flammable hazmat placards collection.

Placard holders are available directly from our hazmat placards collection, with permanent bolt-on and adhesive-mount styles for different vehicle and container surfaces. For carriers who transport multiple hazmat classes, our flip-file placard system combines a durable holder with stainless steel spring clips that lock legends firmly in place at highway speeds while allowing fast, tool-free legend changes between runs.

Non-flammable placards are used when transporting gases that don’t catch fire. These are a type of Class 2 placards and are green in color. We offer these in both tagboard and adhesive vinyl materials.

The 1267 placard is a hazmat placard used to indicate Class 3 flammables being transported. More specifically, it denotes petroleum crude oil identified with the UN number 1267.

Your choice of flammable placard will depend on the material you will be transporting. Class 2 flammable placards are for gases, Class 3 for flammable and combustible liquids, and Class 4 for flammable solids, spontaneously combustible material, and substances that may be dangerous when wet. Many of these placards carry unique UN numbers to identify specific materials further. You may refer to this federal resource for more precise details.

Blue flammable placards indicate that a material is dangerous when wet, meaning it reacts with water to produce flammable or toxic gases. This hazard class falls under DOT Class 4.3 and requires a blue diamond placard with the words "Dangerous When Wet" to warn emergency responders and handlers that water-based firefighting methods must not be used. Common materials requiring blue placards include sodium, calcium carbide, and certain metal powders. Our dangerous when wet placards and full range of hazmat placards are available in DOT-compliant formats to keep your transport operations properly identified.
