What is a key requirement for storing combustible chemicals?

The requirement for storing combustible chemicals in proper containment in sealed containers is crucial for safety and effectiveness. Storing these chemicals in sealed containers helps to prevent leaks, spills, and evaporation, which can lead to hazardous situations. When chemicals are contained properly, the risk of accidental exposure to heat sources, open flames, or other ignitable materials is significantly reduced. Additionally, this practice minimizes the potential for mixing incompatible substances that could otherwise react and cause dangerous conditions. Therefore, proper containment is a fundamental aspect of handling combustible chemicals safely.
