The gates
Release. Nobody enters before the fire department releases the structure. Ask them which areas are unsafe and whether gas, power and water are shut off.
Structure. Sagging ceilings, bowed walls, charred floor framing and a roof with burn-through are reasons to stay out of those areas until a crew or an engineer has looked. Walk only where the floor is visibly intact and do not go under damaged ceilings.
Utilities. Gas stays off until the utility or a plumber clears it. Power stays off in affected areas until an electrician has checked; wiring exposed to heat is unsafe even if it looks fine. Water may be off or contaminated.
Air. Soot particulate and combustion byproducts are irritants; older houses may release asbestos and lead when fire-damaged materials are disturbed. Keep entries brief, wear an N95 or better, and leave the longer work to crews in respirators with scrubbers running.
Retrieval
Once released and in intact areas: medications, documents, wallets and keys, phones and chargers, glasses, children's and pet supplies. Photograph as you go. Touch as little as possible and do not wipe anything.
What not to do inside
Do not run the HVAC or fans. Do not switch on electronics. Do not use the stove, oven or microwave. Do not eat or drink anything that was in the house. Do not start cleaning. Do not throw anything away.
Children, pets and anyone with respiratory conditions
Stay out until the house is clean. Soot and odor are hardest on the youngest and the most vulnerable.
When it is habitable again
After cleaning and deodorizing, utilities restored and inspected, and the odor check passed with the house closed up. The crew tells you honestly; your additional living expenses coverage pays for somewhere to live until then.
