Final answer:
When working with flammable materials in a chemistry lab, it is essential to avoid open flames or heat sources, wear protective goggles, and follow all safety instructions. Keep work areas well-ventilated and free of flammable substances.
Step-by-step explanation:
Safety Precautions for Using Flammable Materials
When working in a chemistry lab, it is crucial to follow safety guidelines to prevent accidents, especially when dealing with flammable materials. Ensure that no flames, sparks, or other exposed heat sources are present around flammable chemicals unless instructed by your teacher. Open flames should be handled with extreme care: by tying back loose hair, tucking in loose clothing, working in well-ventilated spaces, and being aware of fire safety equipment location.
Always wear protective goggles and never leave Bunsen burners unattended. Make sure your work area is free from anything flammable when using an open flame. Additionally, never eat or drink in the lab, make sure to clean all beakers and test tubes thoroughly, and report any accidents or irregularities to your teacher immediately.
At the end of any practical experiment, it's essential to turn off all Bunsen burners, seal chemical containers properly, and never take chemicals out of the laboratory. Always remember the dangers of inhaling fumes and exercising caution when handling hot glassware and chemicals.
