Because natural gas is highly flammable, any spark from electrical appliances could ignite it.

Do not flip any switches on or off.

If you are close to any cooking units, turn them off as fast as possible before evacuating.

However, if they are not within reach, get out of the house.


After suspecting the gas leak, you should not make any calls in the house. Using the phone might spark the gas.

2. Evacuate

Leave the house as soon as you can. Staying in the house for too long increases your risk of getting sick or passing out.

This will reduce the risk of property damage.
