 Rock climbing is a very effective form of exercise. Requiring the coordination of many different muscle groups, climbing can help tone, strengthen and define the body. It can also provide a strong sense of accomplishment upon reaching defined and accessible goals. However, rock climbing indoors or outdoors can be dangerous. Sigonella's MWR runs an indoor rock climbing facility called the CAVE. They maintain the routes and train climbers on safety and proper use of the facilities. Nathan McMullen, senior trainer for Entrepreneurs UK, performs an annual inspection on the CAVE as well as training the instructors to better serve the climbers. Safety is critical. We want them to not only deliver the utmost safety and good practice with their sessions, but we also want them to deliver quality sessions where people learn about climbing and get psyched for that and want to come back and do more. During the inspection, McMullen removed all the holds from the CAVE, cleaned, tested and rearranged the routes to provide some variety for the climbers. Three auto belay mechanisms were installed to give experienced climbers the option to climb safely without a partner. We work with a lot of centres in the UK. I think something like half a million people go through each year through the centres we work with, maybe more than that. We record a lot of instances, near misses, accidents that happen, so we see a lot of different things. And there are some serious accidents. People can get very hurt in this environment. You don't want to fall off the top of the wall and hit the floor. So what we take is we compile all that information and we look at trends in the industry, what's going on and develop procedures and processes to help avoid that and prevent the problems. And it generally works. We do have a pretty good safety record, so that's what we try to keep. From the CAVE at Naval Air Station, Sigonella, I'm Seaman Luke Askew.
