While the family who lived here and investigators try to figure out what caused the tank to explode, Chief Kurtis Wilson with Jacksonville Fire Rescue showed us some things you can do right now to make sure your propane tank or grill is as safe as possible. KURTIS WILSON/DIVISION CHIEF OF OPERATIONS 22:51:58-5233 What you're seeing here is a typical BBQ grill set up propane that uses a 20 pound cylinder and underneath you're going to have a service line. And so for us most of the calls that were going to see if there's leaks or issues will be around those fittings right here.They come loose over time. If you want to check and see if yours is loose, Chief Wilson says its quick and easy. KURTIS WILSON/DIVISION CHIEF OF OPERATIONS 22:54:55-5515 A simple water bottle that you would get from your garden you know or something fill it up with water take a little dab of dish detergent put it in there and then all you would do is come over squirt the valve if this valve is hooked up you would simply squirt the fittings and if you have a leak you'll immediately see it. Like your kids blowing a bubble you're going to see that appear on your hose.) KURTIS WILSON/DIVISION CHIEF OF OPERATIONS 225223-33 the other great thing about propane is that it's odorized. And so everybody kind of knows what propane smells like and so they do that for a reason and that's to let you know hey I've got a problem. 33 Another issue Chief Wilson sees is overfilling. Propane expands in high temperatures, and overfilling can also cause leaks. He says keeping your valve secure is still something to be mindful of even though technology has improved. KURTIS WILSON/DIVISION CHIEF OF OPERATIONS 22:50:44-57 You know about 10 3 Some other things Chief Wilson mentioned, make sure your propane tank or grill is outside in a well vventilated area.Make sure you follow the manufacturers instructions, even if you think you've got it down.
