First-Response Checklist

Smoke & Soot First-Steps Checklist

Check off each step as you complete it. The checklist covers what to do and what to avoid in the first two hours after a fire or smoke event in a Fairfax County condo or commercial building. Items in red are things to avoid - common mistakes that spread soot and increase restoration cost.

Progress: 0 of 12 steps

Step 1 - Do

Confirm the fire is out and the space is safe to enter

Do not re-enter a fire-damaged space until the fire department has cleared it. Structural collapse risk, hidden hot spots, and CO hazard are all present even after visible flames are extinguished.

Step 2 - Avoid

Do not wipe soot with a dry cloth or paper towel

Dry wiping smears wet (grease-fire) soot deeper into the surface and spreads dry soot across a larger area. Both actions increase the cleaning scope and cost. Leave all soot-coated surfaces untouched until the crew assesses the soot type.

Step 3 - Do

Shut the HVAC system off immediately

Every minute the HVAC runs after a fire event distributes soot particles through the air-handler system to every room in the zone. In multi-unit buildings with shared return-air plenums, adjacent units can receive soot from your event. Shut the system off - not fan-only, fully off.

Step 4 - Avoid

Do not use household cleaners on soot-covered surfaces

Applying water-based cleaners to wet (grease-fire) soot causes saponification - the greasy residue reacts with alkaline cleaners to form a soap compound that spreads farther and is harder to remove than untreated soot. The wrong chemistry can permanently set residue on painted surfaces.

Step 5 - Do

Open exterior windows briefly to reduce airborne particle concentration

Brief ventilation (5-10 minutes) reduces the concentration of airborne soot particles in the immediate space. Keep this brief - extended ventilation during humid weather can introduce moisture that interacts with soot residue. Close windows before the crew arrives.

Step 6 - Do

Photograph and video all affected areas before anything is moved

Walk every room with your phone camera and record the soot pattern, affected surfaces, and any contents damage. This documentation establishes the pre-restoration condition for your insurance claim. Photograph from multiple angles in each room. Timestamp matters - do not delete originals.

Step 7 - Avoid

Do not power on electronics that may have been exposed to soot

Soot is electrically conductive. Powering on a computer, monitor, or other electronic device with soot deposits inside can cause short circuits and permanently destroy the device. Electronics must be assessed and professionally cleaned before any power-on attempt. Tag each affected device and leave it off.

Step 8 - Do

Call (571) 741-6292 for soot type assessment and cleaning

The soot type (wet from grease/protein fires; dry from electrical or wood fires; protein residue from overheating food) determines which cleaning chemistry is required. Applying the wrong chemistry to the wrong soot type spreads it or sets it permanently. Call (571) 741-6292 before any cleaning begins.

Step 9 - Do

Notify your property manager and HOA (condo/multi-unit buildings)

Most Fairfax County condo governing documents require notification to the property manager within 24-48 hours of any damage event. For commercial buildings, notify your building management company. Property managers control contractor access to mechanical rooms, freight elevators, and common areas that the crew may need.

Step 10 - Do

Notify your HO-6 or commercial property insurer

Report the event to your insurer promptly - most policies require timely notification. Have your documentation photos ready. For HO-6 condo policies: smoke damage from a neighboring unit is typically covered. For commercial policies: confirm whether the event falls under property damage or fire damage coverage.

Step 11 - Avoid

Do not run portable fans to "air out" soot-affected rooms

Fans disturb settled dry soot particles and redistribute them as airborne particles that travel further through the space and HVAC system. In a room with significant dry soot (from an electrical fire or fast-burning event), fan disturbance can dramatically extend the soot deposit area. HEPA air scrubbers - not fans - are the correct tool for airborne particle reduction after a fire event.

Step 12 - Do

Keep people and pets out of soot-affected areas until assessment

Soot particles are a respiratory hazard - fine carbon particles with absorbed combustion byproducts (VOCs, PAHs) that cause respiratory irritation on inhalation. Children, elderly individuals, and anyone with respiratory conditions should remain out of affected areas until HEPA air scrubbing is complete and clearance readings are below action thresholds.
