The primary consideration in storing chemicals is segregation. This practice involves separating incompatible chemicals to prevent dangerous reactions, spills, or fires that could occur if these substances were to mix. For example, flammable materials should be stored away from oxidizers that can exacerbate a fire. Proper segregation also extends to ensuring that hazardous and non-hazardous substances are kept apart, along with segregating chemicals based on their physical state (solid, liquid, gas). This fundamental aspect of chemical storage is crucial for maintaining a safe work environment and prevents potential accidents or incidents in the workplace.

While temperature control, volume limits, and labeling are also important factors in chemical storage, they do not take precedence over segregation in terms of preventing hazardous situations. Temperature control ensures that chemicals are stored at conditions that maintain their stability but doesn’t address the risk of incompatible reactions directly. Volume limits help minimize risk but rely on the proper segregation of chemicals to be truly effective. Labeling is critical for identification and safety but serves as a secondary measure once proper storage protocols, such as segregation, are in place.
