Final answer:
The statement is true, wearing goggles and taking precautions are important safety measures in a science lab.The question pertains to laboratory safety during a Chemistry class experiment.
Step-by-step explanation:
The student's question seems to be concerned with a “practical demonstration” in a science class, more specifically a Chemistry class, where safety measures, such as wearing goggles and being prepared to duck, were taken in anticipation of the potential for an explosion. This scenario highlights the importance of laboratory safety. Ensuring safety in the lab includes never eating or drinking to avoid ingesting harmful substances, cleaning materials thoroughly to prevent unwanted reactions, being cautious around flames to prevent burns or fires, and knowing how to respond to accidents, which could include filling out an accident report. When handling chemicals or conducting experiments, wearing goggles and using fume hoods or other protective gear to prevent inhalation of harmful fumes is critical. It is also important to always follow teacher instructions and lab guidelines to maintain a safe learning environment.
Wearing goggles and taking precautions like ducking when a test tube is being exploded in the lab are important safety measures in a science experiment. Safety guidelines such as wearing goggles and following the instructions given in lab instructions and by the teacher are crucial to prevent any accidents or injuries.
