Which type of material is acceptable for floor liners when transporting Division 1.1 or 1.2 materials?

In the context of transporting Division 1.1 and 1.2 materials, which involve explosives with a high potential for mass detonation, it is essential to select materials that minimize risks associated with fire and explosion. Non-ferrous metals are the most suitable choice for floor liners because they do not react adversely with explosive materials, reducing the likelihood of causing sparks or other ignition sources during transportation.

Non-ferrous metals, such as aluminum or stainless steel, provide a sturdy, durable surface that can safely contain any potential leaks or spills without compromising safety. This characteristic helps to mitigate risks associated with the highly sensitive nature of explosives, thereby ensuring compliance with safety regulations.

Other materials like plastics may pose risks as they can melt or catch fire in the presence of high heat or sparks. Concrete, while strong, could potentially degrade under certain conditions related to explosive materials. Wood, being organic, is highly combustible and not suitable for use with materials that present high explosion risks. Therefore, non-ferrous metals are the safest and most appropriate choice for floor liners when transporting Division 1.1 or 1.2 materials.
