If you think there may be a fire in your wall, it is important to take immediate action. The first step is to call 911. Once the authorities have been notified, they will be able to assess the situation and determine whether or not there is an active fire.
There are a few signs that there may be a fire burning in your wall:
1. You can see flames or smoke coming from cracks or holes in the wall.
2. The paint on the wall is blistering or peeling.
3. There is an intense heat coming from the wall.
4. You can hear crackling or popping noises coming from within the wall.
5. The room smells like something is burning (e.g., acrid smoke).
If you notice any of these signs, it is imperative that you get out of the house immediately and wait for help to arrive. Do not try to put out the fire yourself, as this could make the situation worse and put you at risk of injury or death.
