Best Practices
  • Conduct structural inspections periodically.
  • Routinely examine metal structures for indications of weakened structural soundness (corrosion, fatigue cracks, bent/buckling beams, braces or columns, loose/missing connectors, broken welds, etc.).
  • Keep corrosive material spillage/build-up removed from metal structures.
  • Report all areas where indications of structural weakness are found
  • Train all persons to recognize and understand safe job procedures before beginning work.
  • Wear fall protection where there is a danger of falling.
