I had a similar problem. I took off the burner heat deflectors and seen gaping holes in the burner tubes. Get your model number and serial number and call Weber. Most Ducane grills have a 5 year warranty on the burner tubes. They will ship them free if under warranty!

Since your grill uses a V - bar flame tamer over the burner, I wouldn't recommend using Lava Rocks. As there is no grate to set them on above the burner. Putting them directly over the V-bar flame tamer, won't allow the burner to heat evenly and you'll have hot and cold spots throughout the cooking surface.
Either the burners are dirty and the holes for the gas to come out are plugged or the gas pressure regulator is bad.
Check the burners and make sure they are clean and if they are then check the regulator.
Are the flames still yellow? If so the burner just needs to be adjusted which is very easy? Look at the ends of the tubes that come out of the burner and end right at the back of the gas controls. You should see a small piece of metal that will slide or spin to close a hole. You want to close or open it a little at a time while the grill is burning. Adjust this until you only see blue flame or blue flames with a little bit of a yellow tip.
It's safe, but you need to keep in mind that propane burns hotter than natural gas, so you won't need to turn the burners up as high for the same heat. Here's an article that explains some of the differences (but doesn't really answer your question): http://bbq.about.com/od/gasgrills/a/aa030505a.htm
Bottom line -- it's safe if you don't leave it cranked up to high flame. Two-thirds flame on propane should give about the same heat as full burner on natural gas.
Of course, you could change the jets. That would compensate for all the differences between NG and propane, and you could run the grill on full high heat if you wanted to.
