Elevated Work Platforms (EWP) Licensing Practice Exam

What tool can be used to ensure that the EWP is level during operation?

1. Measuring tape

2. Spirit level

3. Laser level

4. Annotated checklist

The correct answer is: Spirit level

Using a spirit level is the most effective way to ensure that an Elevated Work Platform (EWP) is level during operation. A spirit level contains a sealed tube filled with liquid and an air bubble that moves within the liquid. When the EWP is placed on a flat surface and is properly leveled, the bubble will sit between two marked lines in the tube, indicating that the platform is level. This is crucial for safety, as an unlevel EWP can lead to instability and increase the risk of accidents or equipment failure during use. While a measuring tape is useful for measuring distances or dimensions, it does not provide information about the levelness of the platform. Similarly, a laser level can be beneficial for aligning structures or determining level over longer distances; however, it is often more complex to use and might not be necessary for quick checks of an EWP’s levelness. An annotated checklist serves as a guide for safe operation procedures but does not directly measure or ensure that the platform is level. Thus, the spirit level stands out as the most immediate and user-friendly tool for this specific purpose when operating an EWP.
