What is the purpose of using safety data sheets (SDS) in a water lab?

The primary purpose of using safety data sheets (SDS) in a water lab is to provide information on hazards and handling procedures associated with chemicals and substances used in the laboratory. SDS are crucial for ensuring the safety of laboratory personnel by detailing the properties of each chemical, including toxicity, flammability, reactivity, and health effects. They also outline proper storage, handling, and disposal methods, as well as emergency measures in case of an accident, such as spills or exposure.

By having access to these documents, lab workers can take the necessary precautions when using or encountering hazardous materials, which is vital for maintaining a safe working environment. This is particularly important in a water lab where various chemicals may be used in testing and analysis, and understanding the potential risks is essential for safe practices.

In contrast, materials such as instructions for water collection methods or laboratory cleaning procedures, although important, do not fall under the scope of an SDS. Additionally, documenting test results is a separate function that relates to data management rather than safety information. Thus, the focus of safety data sheets is squarely on hazards and safety measures, making the selection of this choice as the correct answer clear-cut.
