• Areas storing materials, components, products, or equipment that may slip or collapse.
• Areas with openings or pits, or zones at risk of subsidence.
• Areas with trees that may fall, areas under or on slopes, hills, or steep soil/rock surfaces.
• Sloped surfaces at risk of landslides; gaps in construction at risk of falling.

• Existing structures that may collapse without reinforcement or support.
• Areas at risk from falling or toppling objects.
• Areas near ponds, lakes, streams, rivers, or the sea.
