Secondary Safety Systems

 Secondary Safety Systems

Catch Fencing

• Steel mesh fencing
• 3–6 m height
• Prevents debris entering spectator areas

Debris Fences

• Additional netting or polycarbonate shields
• Used near grandstands

Earth Berms

• Raised soil banks
• Natural energy absorption

4. Placement Strategy (Typical Layout for Car Pack )

High-Speed Straights

• Concrete wall + SAFER/TecPro
• Catch fencing

Medium-Speed Corners

• Tire stacks or TecPro
• Gravel runoff before barrier

Low-Speed Sections

• Tire walls or Armco

Pit Lane

• Concrete wall with fencing
• Minimal deflection design

• 5. Design Principles

  
  
   Effective barrier systems must:
  • Absorb energy progressively
  • Prevent car rebound onto racing line
  • Avoid snagging wheels or chassis
  • Be modular for quick repair
  • Protect both drivers and spectators

  • 6. 2000-Era vs Modern Comparison

    Feature	Circa 2000	Modern Standard
    Main protection	Tire + Armco	TecPro + SAFER
    Energy absorption	Moderate	High
    Repair time	Slow	Fast modular
    G-force reduction	Limited	Improved significantly
