Use the following tips to keep safe when you're out rock climbing:- 

(a) Always Check Harnesses. After you‘ve geared up, always check that both the climber‘s and belayer‘s harness buckles are doubled back. 

(b) Always Check Knots. Before you start climbing, always double check that leader‘s tie-in knot (usually a Figure-8 Follow-Through) is tied right and finished with a backup knot. Also check that the rope is threaded through both the harness waist loop and the leg loops. 

(c) Always Wear a Helmet. A climbing helmet is essential if you want to live long and prosper. Always wear one when climbing or belaying. Helmets protect your head from falling rocks and from the impact of falling. 

(d) Always Check the Rope and Belay Device. Before you lead a route, always double check that the rope is properly threaded through the belay device. Also, always make sure the rope and belay device are attached with a locking carabineer to the belayer‘s harness. 

(e) Always Use a Long Rope. Make sure your climbing rope is long enough to reach the anchors and lower back down on a sport route or to reach a belay ledge on multi-pitch routes. When sport climbing, if you have any doubt that the rope is too short, always tie a stopper knot in the tail end to avoid being dropped to the ground. 

(f) Always Pay Attention. When you‘re belaying, always pay attention to the leader above. He‘s the one taking the risks of a fall. Don‘t visit with other climbers at the base, talk on a cell phone, or discipline your dog or kids. Never take the leader off belay unless you are absolutely certain he is tied in and safe and he communicates that to you.
