What To Do If You Left Gas Stove On For 30 Minutes
1. Turn Off The Gas Stove Immediately
If you left the gas stove on without a flame, it’s best to turn it off as soon as possible.
Most people will leave the gas stove on with food on top. This is normal, but when you leave it on and there’s no food on top, there are serious safety issues to keep in mind.
This is why the first thing you should do is stop the problem at the root. This means turning off the gas stove once it’s time to clear the air.
If the gas stove is still on, anything you do to fix the issue is only going to get worse or remain the same.

2. Open A Window
The best option is to open a window right away.
The window is going to improve the ventilation in the room and provide an exit for the smell that’s in the air.
Otherwise, the air quality is going to remain the same as it settles into the kitchen. You have to immediately open the window and ensure fresh air comes in.
3. Set Up A Fan To Clear The Air
If a gas stove was left on for too long, it’s important to set up a fan in the kitchen.
This is also true for those who don’t have a window in the kitchen. If you don’t have a window, the best alternative is to set up a fan facing toward a room that has a window.
This will help spread the smell and also make sure it does leave the property once it enters the other room.
How Long Does It Take For Stove Gas To Dissipate?

It’s important to take action right away in a situation such as this.
The longer you wait, the worse it gets.
