Robert, LOL---Yep if you dont do it correctly, you have enough pressure, and no containment, it can make a mess--AND create a projectile.
I created a stir many years ago when I stated that I was doing integration testing of hose and hose end stem design at 7500 psi. Guys thought I was nuts. But, sometimes you just have to know. (Actually for -3 and -4 I used to go to 9900 which was the limit I could get back then.) So, if you can make the assembly hold together at those high pressures, then certainly there is no issue at the low pressures we use. WE use 2000 as our test point for assemblies -2 through -8, then 1000 for our -10 through -16 convoluted hoses. Wayy above they actually see in real life. The integration test point for the -10 hoses that some of you have for inverted oil systems was 4500 psi. LOL good thing I have a GREAT cabinet--hose end blow off at 5500 sounds cool, but the mess----but you just gotta know!!!
