Gas Grills
Actually propane gas grill tanks are very safe, close the service valve after each use. Back in the 90’s the federal government required all propane cylinders under 40# to have an over fill protective service valve. Each of these tanks are regulated by the DOT regarding years of service, a new tank can be refilled for 12 years, then one visual re-qualification that is good for another 5 years. A DOT cylinder has a working relief valve in the service valve of 375 psi the relief will pop off should the internal pressure reach that, propane at 60 degrees has a working pressure of 102.5 psi, at around 100 degrees it would be about 175 psi well below the relief valve psi. The only way a grill cylinder could have an issue would be if the tank were to be over filled, very unlikely with the Over Fill Protective Valves that are installed, but is has happened. The other would be user error, in the case of a gas grill catching on fire and burn the hose that connects to the grill cylinder the large nut used to connect to the tank would burn and pop out of the service valve shutting off the propane service from the tank. Sorry for the long reply, I’ve spent 25 years in the propane industry and wanted to share facts.
