What should you inspect on a carabiner before use?

• A. Brand and model
• B. Color of the paint
• C. Gate operation, locking mechanism, body integrity, wear, burrs, cross-loading signs
• D. Age

Answer: (C)

Before using a carabiner, check that it will function safely under load by focusing on how it actually performs and shows wear. Test the gate to ensure it opens smoothly and closes completely, with no sticking and with a reliable spring-back when released. For locking types, verify the locking sleeve engages properly and stays locked during use, and that it can be unlocked when you intend to detach it. The body should be free of cracks, bending, deep scratches, gouges, or any deformation that could weaken it. Look for wear around the gate and on the body, especially where the rope or other gear contacts the carabiner; excessive wear can create sharp edges or reduce strength. Check for burrs or sharp protrusions that could damage rope strands or snag gear. Be alert for cross-loading signs, such as the carabiner carrying load along the wrong axis, which can open the gate or bend the spine and compromise strength. Painted color or brand alone doesn’t guarantee safety, and age isn’t a definitive indicator either—the actual condition and proper function are what matter most.
