Orientation -- Manlift Safety(English)

Explanation
An aerial lift and a scissor lift are not the same thing. While both are used for lifting workers or materials to elevated areas, they have different designs and functionalities. Aerial lifts are typically equipped with a bucket or platform that can be raised or lowered using a hydraulic system, allowing for vertical movement and horizontal reach. On the other hand, scissor lifts have a crisscrossing mechanism that extends and retracts, providing vertical movement only. Therefore, the statement that an aerial lift and a scissor lift are the same is false.

Explanation
Joint allows the arms to be twice as long

Explanation
The statement is true because the work platform on a scissor lift is designed to be smaller than the base. This is done to ensure stability and prevent tipping over. The base of the scissor lift provides a wide and stable foundation, while the platform is typically smaller to allow for easy maneuverability and access to tight spaces. By keeping the platform smaller than the base, the scissor lift can safely lift workers and equipment to elevated heights without compromising stability.

Explanation
The terrain is a major factor that needs to be considered

Explanation
The number of employees needed affects the type of lift that can be used because different lifts have different capacities and capabilities. If there are only a few employees available, a smaller lift may be sufficient to complete the task. However, if there are a large number of employees, a larger lift may be required to accommodate everyone and ensure their safety. Therefore, the number of employees needed does have an impact on the type of lift that can be used.

Explanation
A pre-start inspection of the lift must be performed before each use in order to ensure that the lift is in proper working condition and safe to use. This inspection helps identify any potential issues or malfunctions that could pose a risk to the users. By conducting this inspection, any necessary maintenance or repairs can be addressed before operating the lift, thereby reducing the chances of accidents or injuries. Therefore, it is important to perform a pre-start inspection before using the lift.

Explanation
An inspection of the surrounding work site in which the lift will be utilized is also required

Explanation
Clearance is ten feet

Explanation
According to the statement, a licensed professional is required to inspect a lift every three months or after 150 hours of operation, whichever comes first. This implies that the inspection should be done regularly and at shorter intervals if the lift is being used frequently. Therefore, the statement is true as it highlights the need for regular inspections by a licensed professional.

Explanation
A lift shall not be modified without written permission from the manufacturer

Explanation
The statement is true because lifts are not designed to function as cranes. Unless the manufacturer specifically designs the lift to lift loads like a crane, it is not safe or recommended to use a lift for such purposes. Using a lift as a crane can pose serious safety risks and may lead to accidents or damage to the lift and the load being lifted. It is important to follow the manufacturer's guidelines and only use equipment for its intended purpose to ensure safety.

Explanation
The statement is true because aerial lifts can be moved with men in the basket if the lift is designed for such operations and there are no hazards present. This means that if the lift has been specifically designed to accommodate the weight and movement of individuals in the basket, and if there are no potential dangers or risks involved in moving the lift with people inside, it is safe and permissible to do so.

Explanation
Two lanyards are required and the platform must be within one foot of the structure

Explanation
The statement is true because the lift operator has the responsibility to ensure the safety of employees working on the ground. By making sure that the boom is never over an employee, the lift operator prevents any potential accidents or injuries that could occur if the boom were to fall or collide with someone. This is an important safety measure to protect the well-being of the workers and maintain a safe working environment.

Explanation
The statement is stating that if a worker is 10 feet or more off the ground, they need additional fall protection equipment if someone is in a lift basket. This means that if someone is working at a height of 10 feet or more and there is someone in the lift basket, it is necessary to have additional fall protection equipment. Therefore, the answer is true.

Explanation
The first step in an emergency shutdown is to ensure that the lift is lowered and safely resting on its supports. This is important for the safety of anyone inside the lift or in the vicinity. Lowering the lift and ensuring it is securely supported prevents any potential accidents or injuries that could occur if the lift were to remain elevated during the shutdown process.
