I had difficulty finding vector art of hazmat (hazardous materials) placards and labels, so I wound up creating my own.
These were designed according to the Department of Transportation’s 2009 CFR Title 49, Volume 2 to the best of my abilities. I offer no guarantees as to their accuracy. I haven’t been trained or certified in any way. I'm also not very active in maintaining these, so the standard I designed these for may evolve over time. I've had very few legitimate inaccuracies reported over the years, but keep these caveats in mind.
You are free to use these graphics in any way you like, personal or professional. You can credit me or not, I'm not real concerned about it.
Each design is available in PDF and PNG format. The PDF includes a color version followed by color separations on subsequent pages for each of the unique inks used in the sign. The PNGs are sampled at 300 DPI.
Placards are intended for marking shipping containers, trucks, and cargo. They measure at least 10.8 inches (273mm) on a side.
Labels are smaller, often adhesive signs at least 3.9 inches (100mm) on a side. They are often affixed to individual boxes or crates.
