Which of the following is a good substitution to use in place of ladder? Choose all that apply.Boom liftScissor liftScaffold

To determine which options are good substitutions for a ladder, let's analyze each one:

1. Boom lift: This is a type of aerial work platform that can be used to reach high places. It is often used in construction, maintenance, and other industries where workers need to access elevated areas safely. It can be a good substitution for a ladder, especially for tasks that require mobility and flexibility.

2. Scissor lift: This is another type of aerial work platform that can lift workers and equipment to higher elevations. It provides a stable and secure platform, making it a good alternative to a ladder for tasks that require working at height for extended periods.

3. Scaffold: This is a temporary structure used to support workers and materials during the construction, maintenance, or repair of buildings and other structures. It provides a larger and more stable working area compared to a ladder, making it a suitable substitution for tasks that require more space and stability.

Based on the analysis, all three options (Boom lift, Scissor lift, Scaffold) can be good substitutions for a ladder, depending on the specific requirements of the task at hand. Therefore, the correct answer is:

• Boom lift
• Scissor lift
• Scaffold
