Which of the following is a common type of EWP?

A scissor lift is a common type of Elevated Work Platform (EWP) because it is specifically designed to raise and lower personnel and equipment to various heights safely. This type of platform uses a crisscross mechanism that allows the platform to elevate straight up and down, providing stability and ease of access to elevated work areas. Scissor lifts are versatile and are often used in construction, maintenance, and warehousing applications where the need for vertical access is necessary.

In contrast, other options like a forklift, cement mixer, and generator serve different functions. Forklifts are primarily used for lifting and moving materials rather than providing a work platform. Cement mixers are designed for mixing concrete and do not have lifting capabilities. Generators are used to provide power and are not related to elevating workspaces. Therefore, the scissor lift stands out as a specialized piece of equipment for accessing elevated work areas, making it the correct choice.
