I had a brand new 7' low pressure hose "explode" shortly after exiting the
water at Manatee Springs. At the end of the dive, while still in the spring
pool, my buddy noticed that my long hose was growing in diameter. I exited the
spring and still had the kit on my back when it went off, scaring the hell out
of my buddy and me. 

Upon inspection, we found that only the outer jacket had exploded. Because of a
faulty connection between the hose and fitting, gas got between the outer
jacket and inner hose. The hose was purchased from a very reputable Florida
cave diving equipment company, who promptly replaced the hose and from what I
understand recalled all of the hoses from the same batch as the one that failed
(no complaints there - they did a good job). In this case the failure did not
prevent the hose from functioning although it did leak, but the point is that
the connections between the hose and fittings are  potential failure points if
not executed properly. 

I now take extra care to inspect my hoses, especially around the connections,
but would probably not have caught the hose that failed. I guess that's why we
have 2.
