Class 4 Flammable Solid Placards

The distinct red and white vertical stripes are a universal symbol for flammable solids. This specific pattern allows handlers and firefighters to identify the hazard class instantly from a distance. Consistent use of these standardized placards is a critical part of maintaining high safety and legal compliance during transport. Our DOT Class 4 flammable solid placard follows all federal stripe pattern and color standards for immediate recognition by emergency responders and inspectors.

Yes, magnetic placards are a great, flexible option for vehicles that haul different hazard classes. They stay secure during transit but are easy to remove when your cargo changes. This versatility helps fleet managers stay compliant without needing to install permanent holders or deal with messy adhesive residues. Our aluminum placard holder is a popular alternative for fleets that need quick and clean placard swaps between different hazard class loads.

DOT regulations require you to mount placards on all four sides of the vehicle: front, back, and both sides. This ensures 360-degree visibility, which is vital during an accident or inspection. Proper placement allows responders to quickly assess the risks and take the right action to protect everyone. For full DOT placard placement requirements, refer to FMCSA hazardous materials transport regulations.

Our placards are made from industrial-grade aluminum or heavy-duty vinyl designed to withstand wind, rain, and road debris. They feature UV-resistant inks that will not fade under intense sun exposure. Investing in high-quality materials ensures your hazard warnings remain clear and legible for thousands of miles of long-distance hauling. Our Class 4 placard is available in both aluminum and vinyl formats engineered for long-term highway durability in all road and weather conditions.
