When working on a suspended scaffold 10 feet or higher above the working surface, or in a bucket truck or aerial lift, what safety device should you wear?

In order to use a scaffold at 10 feet or higher above the working surface, some things might be bare in mind. For example, the scaffold and scaffold component must support with no failure its own weight and, at least, 4 times the maximum load applied, a qualify person must design it, each platform must packed and decked as fully as possible with an space between the platform and uprights of no more than 1 inch, solid wood. 

Imma gonna say go with the very first answer (:
