Safety first, right? These explosives placards from J.J. Keller are exactly what you need for DOT-compliant hazardous materials shipping. Each pack comes with 25 permanent self-adhesive vinyl placards measuring 10.75 x 14.875 inches - the official size required by regulations. Here's how they work: the base placard comes pre-printed with 'EXPLOSIVES,' the hazard class (1), and symbol, then you remove the appropriate division number (1.1A-1.3L) from the margin and apply it where needed. The high-tack permanent acrylic adhesive sticks like crazy to clean, smooth surfaces and can handle temperature extremes from -40°F to +200°F. These aren't flimsy stickers either - they're made from durable .0034-inch thick flexible vinyl film that lasts up to 5 years outdoors depending on your conditions. Perfect for trucks, containers, storage areas - anywhere you need clear explosives identification. The 90-pound peel-off liner makes application straightforward, and the bright colors and bold text ensure maximum visibility. Stay compliant and safe with these professional-grade hazard placards.
