Need a professional-looking hazard sign for chemical storage, tanks, or doors?

This SmartSign NFPA magnetic sign kit lets you build your own compliant NFPA diamond placard.

The kit includes a blank 17-inch tall (tip-to-tip) diamond-shaped sign with a heavy-duty magnetic backing – it sticks firmly to any steel surface but can be moved or removed easily.

You also get a set of fifteen 4-inch digits (numbers 0-4, three of each) and six NFPA symbols: Acid, Alkaline, Corrosive, Oxidizer, Use No Water, and Radioactive.

The sign is laminated with a clear UV-resistant film, so it lasts up to 10 years outdoors, resists chemicals, weather, and graffiti.

Even better, it's made with 3M Engineer Grade reflective material – in a blackout or at night, a simple light (like a flashlight) makes the sign pop, helping firefighters and emergency crews quickly see the hazards.

SmartSign is a certified 3M fabricator, so you're getting a quality, durable sign.

The kit comes in wrinkle-free flat packaging to ensure everything arrives in perfect shape.

Ideal for industrial facilities, labs, warehouses, or anywhere you need clear, durable hazard communication.
