Final answer:
Before using any hazardous substances, it is vital to check the MSDS to understand their properties, risks, proper handling, and disposal methods to ensure safety and avoid accidents.
Step-by-step explanation:
When to Check the MSDS
The Material Safety Data Sheets (MSDS) provide crucial information about chemicals' properties, hazards, safety precautions, and procedures for handling, storage, and disposal. It is essential to check the MSDS before using a hazardous substance, when cleaning up a leak or spill, at the beginning of a shift, and after handling chemicals to ensure proper disposal. The MSDS informs users of the risks and the necessary precautions when working with chemicals to prevent accidents and environmental damage.
It is also vital to follow the safety guidelines, such as hand washing after handling materials, proper disposal according to your teacher's instructions, and being cautious with flammable chemicals and heat sources.
Laboratories have specific rules to maintain safety, including not eating or drinking in the lab, cleaning all materials thoroughly to prevent chemical reactions, and knowing the location of emergency equipment like fire extinguishers and eyewash stations. Always be vigilant and inform your teacher immediately of any incidents.
