What is an important factor to consider when storing hazardous materials?

Considering potential reactions with other stored materials is crucial when storing hazardous materials because various substances can interact in ways that create dangerous situations. For instance, certain chemicals can produce toxic gases when mixed, become flammable, or even lead to explosions. Understanding the compatibility of different materials ensures that they are stored in a way that minimizes risk to people and the environment.

While packaging materials, labeling, and accessibility near exits have their own importance—such as ensuring proper containment, safety communication, and operational efficiency—they do not directly address the immediate risks that arise from the chemical interactions between hazardous materials. Thus, awareness of potential reactions is the most vital factor for safe storage practices.
