Class 2 Poison and Toxic Gases are often shipped via highway, railroad and by boat. For crucial safety purposes, laws are in place regarding the tagging of shipments of poison and toxic gases hazardous materials. Thus, P.O.P. 49CFR part 172.500 demands that placards must be visibly mounted to advertise the existence of Class 2 Poison and Toxic Gases hazardous materials. Get high grade and superior durability placards that strictly adhere to the laws, and are offered in three displays. The wordless placards are ideal for international use, while the poison gas placard and toxic gas placard are illustrative notifications of hazardous materials in the shipment. The placards can be ordered as a heavy duty tagboard, or a self-adhesive vinyl material.
