Which of the following is the best practice for loading hazardous materials?

Keeping incompatible materials separate is vital in the loading of hazardous materials because it significantly reduces the risk of dangerous reactions during transport. Certain substances can react negatively with one another, potentially leading to fires, explosions, or the release of harmful gases. By ensuring that incompatible materials are stored apart, you protect the safety of personnel, the environment, and the integrity of the cargo.

In contrast, tightly loading products to save space, or using any available space regardless of material type, could result in situations where incompatible materials may come into contact, heightening the risk of incidents. Loading hazardous materials last might help in organizing the load but does not address the fundamental safety concerns related to material compatibility. Thus, keeping incompatible materials separate stands out as the best practice for managing hazardous materials safely.
