Final answer:
A utility knife is used to cut materials like fabric, cardboard, and foam core; it's important to retract the blade for safety when not in use. Safety in using tools and equipment is crucial in various settings, whether in crafts or science experiments.
Step-by-step explanation:
A utility knife is used to cut fabric, cardboard, or foam core; make sure the blade is retracted before you put it away. This tool is essential for meticulous cutting tasks in various crafts and projects. While working with a utility knife, safety is paramount. Ensuring the blade is retracted helps to prevent accidents and injuries when the tool is not in use. For similar safety reasons, when using kitchen tools like a plastic cutting board, it is deemed safer than a wooden cutting board as it is less likely to harbor bacteria. In a different context of safety, when working with heat sources such as Bunsen burners, it's critical to be cautious by securing loose clothing and working in a well-ventilated space to avoid burns and fire hazards.
