This situation applies to Philadelphia US and to its type(s) of meter. It is not fair to therefore say “all smart meters are a fire danger”.
What it is fair to say is “authorities claiming unconditional safety of untried and unproven electrical devices should be aware of the risk of being wrong in some instances. They need to be conscious of their responsibility to the public, even if the government seems to be offering rhetoric support. They too are relying on too little or unscientific information.
Australian smart meters may by safe but equally so may that not be safe, electrically or radiation wise. They have not been PROVEN to be otherwise!
