Verified step by step guidance1
Understand the importance of safety in the chemistry laboratory, especially when handling chemicals that may be hazardous.
Recognize that Safety Data Sheets (SDS) provide detailed information about each chemical, including hazards, safe handling, storage, and emergency measures.
Before using any chemical, students should read the SDS to learn about the specific risks and precautions associated with that chemical.
Review proper handling procedures such as wearing appropriate personal protective equipment (PPE), knowing how to store chemicals safely, and understanding what to do in case of spills or exposure.
Avoid assumptions like wearing gloves only with acids or mixing chemicals without checking compatibility, as these can lead to dangerous situations.
