Final answer:
The Material Safety Data Sheet (MSDS) should always be reviewed before working with unknown chemicals to understand their hazards and proper handling. This ensures laboratory safety along with adherence to proper protocols, including ventilation, the use of safety equipment, and no lone work on experiments.
Step-by-step explanation:
Before working with any unknown solvents, chemicals, or refrigerants, always review the Material Safety Data Sheet (MSDS). The MSDS contains critical information on how to handle chemicals, potential hazards they pose to your health and to the environment, and instructions on their safe disposal. It is essential to consult these data sheets anytime you work with a new chemical to ensure proper safety measures are taken. Moreover, safety in the laboratory is paramount, which includes understanding the risks associated with flammable chemicals, fumes, and handling of sharp objects and electrical equipment.
Following the safety guidelines provided by your school or workplace is necessary to maintain a protected environment. This includes proper ventilation, never performing experiments alone, adhering to instructions, and making sure to utilize safety apparatus such as fume hoods and eyewash stations.
