OSHA 30 Hour Construction Program Practice Test

What type of scaffold is supported by two bearers and hung from a fixed support with ropes?

1. Suspended scaffold

2. Platform scaffold

3. Float scaffold

4. Frame scaffold

The correct answer is: Float scaffold

The correct answer is a suspended scaffold. This type of scaffold is characterized by being suspended from overhead supports using ropes or other means. Suspended scaffolds are designed to be adjustable, allowing workers to raise or lower the platform to the desired height. This is particularly advantageous for tasks such as window washing or high-rise construction, where access to the building's exterior is necessary. In contrast, platform scaffolds are usually set on the ground and don't rely on overhead support. Float scaffolds are typically used for jobs over water and often aren't truly hung from supports in the same way. Frame scaffolds consist of prefabricated frames that are set up on the ground and provide a stable, free-standing platform for workers. Each of these other options serves a different purpose in construction and maintenance activities, emphasizing why suspended scaffold is the appropriate choice in this context.
