When securing a load with rope, what minimum rope diameter is recommended?

• A. 15 mm
• B. 10 mm
• C. 20 mm
• D. 5 mm

Answer: (B)

Using rope to secure a load requires enough thickness to carry the tension without failing and to resist wear at edges and fittings. A minimum diameter of 10 mm is recommended because it provides a solid safety margin: it’s strong enough for typical loads, stands up better to abrasion, and holds knots and fittings securely. Thinner rope, like 5 mm, is more prone to breaking or slipping under tension, which can lead to the load loosening. While thicker rope (15 or 20 mm) could offer extra strength, it isn’t usually necessary for standard loads and can be harder to handle. Prioritise a rope around 10 mm with good condition and appropriate edge protection to keep securing reliable.
