Rusted

• Normally, gas meters don't suffer from rust unless their environments are abnormal. Excessive rain, snow or a humid climate may cause rust. If the gas meter is located to close to a clothes dryer vent, this may lead to premature failure because of the moist air. If the meter is located inside, it can rust due to repeat exposure to chemicals. It is wise to store paint solvents or other corrosive chemicals outside in a well-ventilated shed. An excessively rusted meter may become unreliable and inaccurate. This can lead to a gas leak, and may close the necessary venting holes.
  
  

Mechanical Damage

• This refers to damage caused by vehicles, lawn tractors or any other device capable of damaging the meter. It can also be caused because of a failure in the support system for the meter. Meters should be located where the chance of mechanical damage is low, or be protected by several concrete-filled steel posts embedded in the ground.
  
  

Ice

• A meter that accumulates excessive ice is a danger. The ice may obstruct the vents on the regulators, which could lead to excessively high gas pressure in the home's piping system. A meter should be located in a position that reduces its exposure to water runoff from roofs or other sources of water.
  
  

Leaks

• A leaky meter is an extreme danger to the occupants of the home. A leak can occur anywhere on the meter, but is typically located at the pipe joints. Gas companies add an odorant to natural gas to give it the smell of rotten eggs. If you detect the smell of rotten eggs in close proximity to the meter, turn off the gas and contact the gas company immediately. Leaking natural gas can lead to explosion and fire.
