What type of floor liners are acceptable for moving Division 1.1 or 1.2 materials?

Moving Division 1.1 or 1.2 materials, which pertain to explosives and are classified as very high-risk hazardous materials, requires careful attention to safety and compliance. Non-ferrous metal, such as aluminum or stainless steel, is the correct choice because it does not produce sparks when struck, thus minimizing the risk of ignition or explosion from any potential contact with explosive materials.

This characteristic makes non-ferrous metal a safer option for the transport and storage of such high-risk substances. It also provides a more robust structural integrity than other materials that may be too weak or chemically reactive.

On the other hand, wood can absorb moisture and may degrade over time, potentially becoming a fire hazard. Plastic, while non-reactive, may not provide the same level of durability or resistance to physical damage under heavy loads or extreme conditions. Concrete, although sturdy, is not feasible for liners in all situations as it can crack under pressure and does not offer flexibility in handling. Thus, non-ferrous metal is the preferred and appropriate material for safely moving Division 1.1 or 1.2 materials.
