Should the floor liner for Division 1.1 and 1.2 materials (Explosive A) be stainless steel?

The correct choice indicates that the floor liner for Division 1.1 and 1.2 materials (Explosive A) must be a non-metallic material. This requirement is primarily based on safety considerations. Non-metallic materials are less likely to produce sparks or react with the explosive substances, reducing the risk of accidental ignition or detonation.

Using non-metallic options, such as polyethylene or other synthetic materials, can also improve the overall durability and resistance to chemical reactions that might occur with metals. Stainless steel, while resistant to corrosion, can still pose a risk due to its ability to generate sparks when struck or subjected to impact. Therefore, the use of non-metallic liners is a crucial safety measure in the handling and transportation of explosive materials, ensuring compliance with regulations that prioritize risk mitigation.
