Which of the following materials are acceptable floor liners for moving Division 1.1 or 1.2 materials?

Class 1 (Explosives) Materials.
Turn your engine off before loading or unloading any explosives. Then check the cargo space. You must: Disable cargo heaters. Disconnect heater power sources and drain heater fuel tanks. Make sure there are no sharp points that might damage cargo. Look for bolts, screws, nails, broken side panels, and broken floorboards.
Use a floor lining with Division 1.1, 1.2, or 1.3. The floors must be tight and the liner must be either nonmetallic material or non-ferrous metal. (Non-ferrous metals are any metal that does not contain iron or iron alloys).
Use extra care to protect explosives. Never use hooks or other metal tools. Never drop, throw, or roll packages. Protect explosive packages from other cargo that might cause damage.
