Final answer:
When broken glass is present, erecting a barrier or directing traffic away is appropriate until the glass can be safely cleared using tools like a dustpan and broom, with gloves and other protective gear used as needed.
Step-by-step explanation:
In the context of safety precautions, when broken glass is involved, the correct action is to erect a barrier around the glass, or to stand near the glass to direct traffic away from it until it can be safely cleared. This is to prevent injury from the broken pieces. It is essential to use tools such as a dustpan and broom while cleaning up broken glass, rather than touching it with bare hands. Gloves should be worn as an additional precaution, if available. Also remember to use protective gear such as goggles or safety aprons when instructed to do so for various safety reasons.
