What other people do as a their safety measure shouldn’t really be a decision helper for you.
Other people might just be lucky. So personally I wouldn't care what precautions someone else takes. It’s all about how comfortable I feel about the precautions I've taken.
Some people feel comfortable with a garden hose, some with a glass of water and some people wont do anything without the fire department on their way their. And of course before I was doing well I probably would have been using gas cans for my fire safety measure as I was probably worth way more on paper than in reality.
Which brings me to my question: why do you care?
