Class 7 Radioactive hazardous materials are extremely dangerous, and most certainly when in transit. For this reason, P.O.P. regulations from 49CFR part 172.500 have instituted that all domestic and international shipments of hazardous materials must have visual identification on the surface of their containers. We offer you two seamless solutions for hazardous materials placards. Go no further than this site for your Class 7 Radioactive placards, which are available in polycoated water resistant tagboard, as well as long lasting self-adhesive removable vinyl placards. The heavyweight tagboard fits flush into standard placard holders, so the placard can be switched out for another if need be. The self-adhesive option mounts easily on shipment surfaces, and peels off leaving no residue as well.
