Why should one turn off gas and electricity supply after an earthquake

Posted by Wayne Bennett on


You have probably heard that you should turn off the gas after an earthquake.

This is because of the strong ground movement and it may damage your pipelines and cause a leak.

And a gas leak undetected will find an ignition source. This will lead to explosion and fire.


How to find gas leaks

If you hear a hissing sound or smell gas inside your home – that tells you there is a gas leak.

But it doesn’t mean that if you don’t hear a hissing sound or smell gas, you’re in the clear.

This is actually a dangerous assumption, because gas could be leaking from the lines that run through the walls and attic in your home.

Your dials are the best way to find leaks.

The Water Meter

Remember you will need a tool to remove the lid from your water box in the ground. The “On Duty” utility shut off tool works perfect for this. One end fits perfectly in the slot on the lid.

You need to also remember not just any wrench will turn off your water. Your typical wrench won’t work because you can’t turn it sideways in the box. You need a wrench that can come in from the top (see pic).  You should make sure you can turn your water valve off. Sometimes they are very difficult to turn because they have been sitting there covered in dirt for years. You should exercise that valve.

The Electrical Panel

When shutting off your power you may want to shut down certain circuits in your home, rather than turn off the entire system if it is an isolated electrical problem. So make sure you have all your breaker switches marked in advance. Also make sure you are not holding on to the panel door with one hand while you are turning off breakers with the other hand  while you are standing on the ground.
