The government does regulate the safety of things like propane tanks, but major retailers, Home Depot included, usually have merchandise quality standards well above what the government mandates. That's suggestive (though not conclusive, I'll admit) that it's Home Depot, and not government safety standards, that keep you safe when you shop at Home Depot.
