Before conducting an experiment, ask yourself, “What would happen if…?” Answering this question requires an understanding of the hazards associated with the chemicals and equipment involved. For each experiment, start by identifying the properties of the chemicals involved. Use Safety Data Sheets (SDS) to find information about the substance or mixture. Chemical manufacturers are required to provi

Prudent laboratory practicesMinimizing chemical exposures is essential. While few laboratory chemicals are entirely without hazards, it’s crucial to adopt general precautions when handling all substances. Additionally, specific guidelines for particular chemicals should be followed. Even for substances with no known significant hazards, exposure should be minimized. Special precautions are necessa
