No matter if the fire was big or small, it’s most definitely not safe for people to inhabit a building that has experienced fire damage. There’s not only the danger of structural damage, there’s also the harmful effects from smoke damage. You may not realise it, but smoke damage can be a very large health risk, and smoke particles aren’t always visible to the human eye. So, even if the fire happened in a kitchen, your upstairs bedroom could be harbouring dangerous smoke particles.
