It's a lot safer now than it was 50 years ago. Just don't stand too close while wearing loose clothing. Most gas stoves are self igniting so when you turn it on, it lights instantly.
My only suggestion is, if you come home after being out for a long while, go, check the pilot light to be sure it is still lit. If not, opened some windows and turn the gas off at the source. Wait a while before turning it back on and lighting the pilot light. And for goodness sake don't light a cigarette before checking the stove. That's the quickest way to find out, but not the best way.
