A moment of inattention, an instant of fatigue, excessive confidence: moments of absence in which one can quickly forget to make a knot in the end of the rope, lock a carabiner, finish the tie-in knot... oversights that often pass without notice until the day an accident happens... To help avoid this, one can adopt a simple habit, the PARTNER CHECK: a mutual checking between climber and belayer before starting each pitch.

Before starting each pitch, the climber and the belayer must each check 4 key areas to ensure climber safety:

Belay system setup:

• rope installed in the proper direction (belay device function check)

• carabiner connected to the correct place on the harness

• carabiner is locked

Harness:

• harness waistbelt above the hips

• harness adjusted to fit snugly

Tie-in knot:

• tied-in to the right place on the harness

• the correct knot

• knot finished and tightened

Rope:

• knot tied at the end of rope.

Remember that before using your equipment, you must have read and understood the supplied Instructions for Use.
