What is the correct statement regarding scaffold access and why is climbing cross-braces unsafe?

The correct statement regarding scaffold access is:

• Employees must not climb the cross-braces to access the scaffold, as this is dangerous and could compromise the structural integrity of the scaffold.

This is because climbing cross-braces is an unsafe practice that can lead to falls and may put undue stress on the scaffold structure, potentially weakening it. Proper access methods, such as ladders or stair towers, should always be used.
