Item DescriptionPlay it safe when shipping explosive substances with Labelmaster's Explosive Class 1.1, 1.2 & 1.3 Placards with Tabs. The classification code for an explosive consists of the Division Number followed by the Compatibility Group Letter. These enable the carrier to complete the Hazard Class 1 placard with the required Division Number: 1.1, 1.2 or 1.3, and the Compatibility Group Letter: A, B, C, D, E, F, G, H, J, K, or L. These letters are used to specify controls for the transportation and storage of explosives to prevent an increase in hazards that might result if certain types of explosives were stored or transported together. These placards meet the requirements in IMDG as well as those in 49 CFR for placarding explosive hazardous material shipments. Made of removable vinyl, they are ideal for limited-time use. The placards measure 273 x 273mm and are sold in packs of 25 or cases of 900.
