Final answer:
Shore or lean-to scaffolding is permitted for use in both interior and outdoor settings, as long as safety precautions are taken. However, there may be restrictions in underground areas and it is important to comply with local regulations.
Step-by-step explanation:
Shore or lean-to scaffolding is generally permitted for use in both interior and outdoor settings, provided that proper safety precautions are taken.
For example, shore scaffolding can be used to support structures during construction or renovation projects, while lean-to scaffolding can be used for various types of maintenance and repair work.
However, there are some situations where the use of shore or lean-to scaffolding may be prohibited. For instance, it would typically be prohibited in underground areas where the structure is not designed to support such scaffolding safely.
Additionally, local regulations and safety standards may vary, so it is important to consult with relevant authorities and follow proper guidelines.
