Shipments of Class 2 Inhalation hazardous materials are required by P.O.P. 49CFR part 172.500 to be identified by placards that indicate the type of hazardous material in transit. The law applies to several modes of transportation, including by freeway, via railcar, and on cargo boats. Class 2 Inhalation hazardous materials pose a considerable safety risk, and our placards effectively guarantee that shipments are in process according to the law. The vinyl self-adhesive Class 2 Inhalation Placards are simple to mount on trucks containing inhalation hazardous materials, and just as easy to peel off. As well, the tagboard placards are heavyweight water-resistant coated and are streamlined to fit snugly into placard holding devices, and effortlessly swappable in the event of shipping a different hazardous material.
