Been thinking about this quite a bit since I got my Smokin-It 2D. Recent tragedy near me: http://www.philly.com/philly/news/20160703_Delco_fire_reportedly_kills_2.html Cause of the fire was thought to be from a propane smoker left on overnight. I've leaned the hard way with the little smoker I have to wear shoes when taking cooked meat out of it (splashed some drippings on my feet), and not to stand over the door when I open it - get a big blast of steam and smoke. Regarding above, I have no idea whether the smoker was close to the house or not - but guessing it was since the house caught fire. Even though my little smoker uses less power than my crockpot (800w vs 1000w), I am not sure I would leave it running unattended - a grease fire inside might well leak out and set my deck on fire. Since I have a townhouse I don't have a lot of place to run it and with kids in close proximity I would not feel comfortable running it on the lawn unattended, either. Anyhow would appreciate other thoughts on safety... Thanks!
