Experts advising NASA are not impressed with SpaceX's plan to fuel rockets while astronauts are aboard, particularly in the wake of the September 1st explosion:
"This is a hazardous operation," Space Station Advisory Committee Chairman Thomas Stafford, a former NASA astronaut and retired Air Force general, said during a conference call on Monday. Stafford said the group's concerns were heightened after an explosion of an unmanned SpaceX rocket while it was being fueled on Sept. 1. Causes of that explosion remain under investigation.
Members of the eight-member group, including veterans of NASA's Gemini, Apollo and space shuttle programs, noted that all previous rockets carrying people into space were fueled before astronauts got to the launch pad. "Everybody there, and particularly the people who had experience over the years, said nobody is ever near the pad when they fuel a booster," Stafford said, referring to an earlier briefing the group had about SpaceX's proposed fueling procedure.
SpaceX needs NASA approval of its launch system before it can put astronauts into space. NASA said on Tuesday it was "continuing its evaluation of the SpaceX concept for fueling the Falcon 9 for commercial crew launches. The results of the company's Sept. 1 mishap investigation will be incorporated into NASA's evaluation."
SpaceX posted updates about the explosion on Oct. 28. The helium loading system appears to have caused the problem. SpaceX wants to resume launches before the end of the year.

the risk is much higher during the fueling process.
If you go back and check all the famous vehicle explosions that NASA and Roscosmos have had you will find that fueling is seldom the issue. Maybe that is because everyone is extra careful, but the accident record does not show that fueling is that risky.
Launch is the major risk point.
Static rockets sitting there fueled and waiting are just about never the risk.
No, you are mistaken. I've always had this sig.

Yes, fueled and ready is just about never the risk. That's why NASA is good with the astronauts boarding then. If a tank was going to burst or a coupling was going to break, it would probably have happened during fueling. That's the part where you don't want anyone near the rocket. It's an avoidable risk.
Naturally, the actual launch and operation of the rocket is more dangerous still, but if it's to be a manned flight, the risk cannot be avoided.
