Without these safety devices, it is possible a flash can occur within the hose, and ultimately follow back into the tanks, causing an explosion. All though these would be an extremely rare occurrence, but flashback arrestors will make it a "never" occurrence. Check valves are first line of defense, only the flashback arrestors will ultimately stop a flashback.
