Why is it important to know the properties of a chemical before using it?

Understanding the properties of a chemical before using it is critical for ensuring proper handling and risk management. Each chemical has specific physical and chemical properties, such as its reactivity, toxicity, flammability, and compatibility with other substances. Knowledge of these properties allows laboratory personnel to implement appropriate safety measures, such as using personal protective equipment, working in suitable environments (like fume hoods), and selecting proper storage containers.

For example, knowing a chemical is highly volatile and flammable would prompt the use of explosion-proof equipment and the implementation of stringent storage guidelines. Additionally, understanding potential health hazards can guide workers on how to react in case of spills or accidents, thus minimizing risks and ensuring a safe working environment.

This knowledge goes beyond just proper storage; it fundamentally influences how chemicals are handled, mixed, and disposed of in the lab, safeguarding both personnel and the environment.
