What is the minimum breaking strength for connectors (MBS)?

What is the minimum breaking strength for connectors (MBS)?

• A. 15 kN
• B. 30 kN
• C. 10 kN
• D. 22.2 kN or 5000 lbf

Answer: (D)

The question is testing knowledge of the standard minimum breaking strength (MBS) rating for connectors. In rope access and PPE practice, connectors are rated to withstand a breaking load of about 22 kN, which is equivalent to 5,000 pounds-force (lbf). This rating is set to survive the dynamic and peak loads that can occur during a fall, providing a safe margin over typical working loads and ensuring the hardware won’t fail under sudden stress. So the value closest to the commonly cited standard is 22.2 kN, or 5,000 lbf. The other options are not aligned with the standard connector MBS values used in rope access practice.
