Did you realize that the OPD valve on your tanks will shut off the flow almost instantly if a line breaks? Do you know at what percentage of o2 and propane is required for ignition? Do you realize how close to impossible that percentage is to achieve in an outdoor setting, especially if there is any wind? Do you know that you can put a lit cigarette out in a can of gas with zero chance of an ignition or explosion? From a former fire chief.
