Just make sure to inspect your hoses and the burners at the start of each grilling season.
I once had a grill fire on my back deck. The result of a bad hose and burner in a cheap grill.
Thankfully, The new tanks have a "blow off valve" that keeps the bottle from exploding while it is on fire or in a fire.
If the bottle gets too hot the valve opens spraying off gas till the pressure is acceptable.
It will keep doing this periodically till the tank is empty.
The noise was scary and impressive, but my home has vinyl siding and it was warped a little, and the deck was "alligatored". All easily replaced.
I now have a Weber and it is a much better design, than the original grill.
We grill a LOT. Like nearly every day of the spring, summer, and fall. And a lot of winter days.
My grill has a bottom that slides out for cleaning. Clean it out a couple times a season.
It will accumulate the charred food that falls thru the grill, and the ashes that you brush off. If you clean this crap out regularly, you will reduce the chance of fire, and the grill won't smoke as much.
Also, keep an extinguisher handy, Just in case. You will likely never need it, but it sure offers a lot of peace of mind.
I've been grilling for 20 some years. Had one fire, as the result of buying and using a poorly designed grill.
Remember, that for safety and convenience a gas grill has a charcoal grill beat all to hell. Though many will argue that charcoal grills cause better taste, a charcoal grill has to be tended for a long time before it's ready to cook on, and hours after you're done using it, till the coals go out.
A gas grill requires a twist of the knob, and in less than 15 minutes it's ready to cook on, and an hour after you're done it's cool enough to cover.
