Final answer:
Scaffold frames must be pinned or secured together whenever they are used to ensure stability and safety. This is a crucial safety measure in construction technology.
Step-by-step explanation:
Scaffold frames must be pinned or secured together whenever they are used to ensure stability and safety. Pinning or securing the frames together helps to prevent accidents such as collapse or falling objects, which can lead to injuries or even fatalities. For example, in the construction industry, scaffold frames are commonly made of metal and can be connected using pins, bolts, or clamps. These connections create a strong and stable structure that can support workers and materials safely. Overall, pinning or securing scaffold frames together is a crucial safety measure to guarantee the stability and integrity of the scaffolding system.
