What is the last piece of equipment put up before entering the grader?

The last piece of equipment put up before entering the grader is the drip pan. This is essential for safety and environmental protection. The drip pan is used to catch any spills or leaks that may occur from the equipment. By placing the drip pan under the grader before starting any work, operators can prevent fluids from contaminating the surrounding area and maintain a safer job site. It also provides a clean environment when the grader is being serviced or maintained.

In this context, while the safety cone is important for marking the work area and alerting others to the presence of equipment, it is not involved in the immediate equipment setup before entering the grader. The fuel cap is relevant when refueling but does not pertain to the operational setup of the grader. The control panel is an essential component for operating the grader, but it is not a piece of equipment that is put up prior to entering the grader; instead, it is part of the equipment itself that the operator interacts with once inside. Therefore, the correct answer emphasizes the importance of addressing potential hazards before work begins by first setting up a safety measure like the drip pan.
