<reasoning>

Analyze safety requirements for personal fall arrest systems (PFAS)

• PFAS anchorages must be independent of any anchorage being used to support or suspend platforms, and capable of supporting at least 5,000 pounds per employee attached.
• Guardrails and hoists are not designed to withstand fall arrest forces and must never be used as anchor points.
• Defective components or equipment subjected to fall forces must be immediately removed from service.

Evaluate the inspection requirement statement

• OSHA standards require that personal fall arrest systems be inspected prior to each use for wear, damage, and other deterioration.
• Any system or component subjected to an impact load must be immediately removed from service and not used again until inspected and determined by a competent person to be undamaged and suitable for reuse.
• Therefore, the statement "They do not need to be inspected before use and after impact" is false.
