DIY cleanup is not recommended due to hazardous soot, odors, and potential structural issues.

Baking soda is an effective fire reduction method. However, flour and baking powder are very dangerous around flames. Flour is flammable and it can also conduct electricity. The combination can cause serious injury from electrical shock and worsen the situation by adding fuel to the fire. Baking powder is also not an option as it's also highly flammable. 

It is generally not safe to live in a house with smoke damage, as even minor damage can pose long-term health hazards and structural risks. While it might seem safe temporarily depending on the severity, you should relocate if there is major damage or visible soot. Smoke smells and residue contain dangerous particulates and chemical compounds, including carcinogens, that are hazardous to breathe and can cause respiratory issues. These signs of damage are not always visible but can have dangerous short-term and long-term effects on your health, belongings, and your home's structural materials. You should not stay in the house until a trained professional from a smoke remediation or restoration company has assessed the damage and determined it is safe to return. Your insurance company may cover the cost of alternative housing while the professional work is completed.

The first step in fire damage restoration is having a pro come in right away to help control moisture (if authorities used water to extinguish a fire at your home). Skipping moisture removal puts your home at risk for invasive mold and rot that can cause added property damage and health issues. Once you have the bulk of the water out, you’ll need to run blower fans for 24 to 72 hours to remove moisture.
