Final answer:
Jerry should test the edges of the sinkhole to see if it could grow in size, and then barricade the perimeter to prevent accidents.
Step-by-step explanation:
Jerry should first test the edges of the sink hole to see whether it could grow in size. This is important because sinkholes can expand and become even more dangerous. Testing the edges can help determine if the sinkhole is stable or if it has the potential to collapse further.
After testing the edges, Jerry should barricade the perimeter of the sink hole so no one will fall in. This can be done by using caution tape, cones, or any other type of barrier that can effectively prevent people from accidentally stepping into the sinkhole.
It is crucial for Jerry to take these measures, especially considering the potential hazards that sinkholes can pose. Sinkholes can continue to grow in size, and if someone were to fall into one, they could sustain injuries or even lose their life. By testing the edges and barricading the area, Jerry can mitigate the risk and ensure the safety of himself and others.
