Fire and Smoke Restoration Technician common mistakes
Fire and Smoke Restoration Technician · Understand the traps and how to avoid them.
Treating smoke residue as a single cleaning problem and applying one method (usually wet wiping or one general-purpose cleaner) to every surface in the structure.
Candidates memorise 'smoke damage = clean everything' and never separate residue types, so they default to a single product. The exam deliberately mixes protein, petroleum, wet, and dry smoke in the same scenario to test whether the candidate selects method by residue and substrate.
What to do instead
Before answering, classify the residue (protein from kitchen fires, oily petroleum soot, wet smoke from smouldering low-heat fires, dry smoke from fast hot fires) and the substrate (painted drywall, unfinished wood, porous vs non-porous, electronics, HVAC). Match the cleaning agent and technique to that pair, and reject any answer that applies one cleaner building-wide.
Skipping or shortcutting the pre-work scope by writing an estimate from the loss report or the adjuster's summary instead of a room-by-room, surface-by-surface inspection.
Time pressure and the habit of estimating from photos or a claim narrative. Candidates then miss hidden affected areas (attic, crawlspace, HVAC plenum, cabinet interiors, closet ceilings) and the exam tests whether the scope reflects actual observed conditions.
What to do instead
Build the scope from a documented walkthrough: room, surface, residue type, affected square footage/linear footage, and method. Include concealed and connected spaces (HVAC, wall cavities opened for inspection, attic) explicitly. Answers that scope only the visibly charred room are almost always the distractor.
Mixing mitigation and reconstruction line items in the same phase without separating emergency services from permanent repairs.
Candidates conflate 'restoration' as one job and forget that drying, board-up, and content protection are emergency mitigation billed differently from rebuild. The exam tests whether the candidate can sequence and classify work correctly.
What to do instead
Separate the estimate into emergency mitigation (stabilisation, drying, temporary power, board-up, content pack-out), cleaning/deodorisation, and reconstruction. Assign each line to the right phase and justify it by the condition that triggered it.
Documenting only the before-and-after condition and omitting the in-progress record: moisture readings, daily drying logs, deodorisation equipment placement, and cleaning product dilution.
Candidates think documentation means photographs of damage. They underestimate how much of the file is built on contemporaneous measurements and equipment logs, which is exactly what the documentation and subrogation domains probe.
What to do instead
For every affected area, record dry standard readings, daily moisture content and psychrometric readings, equipment placed and hours run, product used with dilution ratio, and who performed the work with date and time. Treat the log as evidence that will be read by a third party months later.
Failing to distinguish the dry standard from the pre-loss condition, and drying to an arbitrary percentage or 'looks dry' judgement.
Candidates memorise 'dry to standard' without knowing the standard is established from an unaffected reference area of the same material in the same structure. They then accept answers that dry to a generic target.
What to do instead
Establish the dry standard by measuring an unaffected, comparable material in the same building (same material, similar assembly, same ambient conditions). Document those readings and dry affected materials to that reference, not to a fixed number pulled from memory.
Recommending replacement of materials that could be cleaned or dried, or conversely attempting to clean materials that are contaminated beyond restoration, without stating the decision criterion.
Candidates answer by gut feel about cost rather than by condition. The exam uses borderline cases (charred structural lumber, smoke-saturated insulation, mouldy drywall, heat-damaged wiring) to see whether the candidate can articulate why a material is restorable or not.
What to do instead
State the criterion explicitly: structural integrity after charring depth is assessed, contamination type and penetration, porosity, salvage value versus replacement cost, and health/safety limits. Then apply it consistently and note the assessment method (e.g., probing char depth, moisture mapping) in the file.
Overlooking HVAC and air-movement pathways as a contamination route, so the scope covers rooms but not ductwork, registers, or the air handler.
Candidates focus on visible surfaces. Smoke travels through the return air system and deposits residue in ducts and on the blower, so the exam tests whether the candidate traces contamination along the air path.
What to do instead
In any fire loss, evaluate the HVAC system: filter condition, duct interior, registers, air handler and coil. Include inspection, cleaning or replacement, and sealing as scope items where residue is present, and document the basis for that decision.
Treating deodorisation as a single step (usually 'run an ozone machine') rather than a process matched to the odour source, and ignoring safety and occupancy constraints of the chosen method.
Ozone is the most familiar term, so candidates pick it reflexively. They miss that source removal, cleaning, and containment come first, and that ozone, hydroxyl, thermal fogging, and vapour-phase options have different applicability and clearance requirements.
What to do instead
Sequence deodorisation: remove the source, clean all residues, contain and control air, then apply the method matched to the odour and occupancy (ozone only in unoccupied spaces with proper clearance; hydroxyl or photocatalytic where occupants or sensitive contents remain). State the rationale and the safety controls in the answer.
Handling spoliation and evidence issues as an afterthought: discarding damaged components, altering the scene, or failing to preserve samples before cleaning begins.
Candidates are trained to restore quickly and treat debris removal as routine. They do not connect early destruction of evidence to later subrogation or liability disputes, which is precisely what the spoliation domain tests.
What to do instead
Before demolition or cleaning, identify potentially disputed items (appliance of origin, failed component, wiring) and preserve them with photographs, chain-of-custody notes, and secure storage. Document what was removed, when, by whom, and where it went, and flag anything that may be needed for a cause-and-origin or subrogation review.
Writing the subrogation narrative as a general description of the loss rather than a cause-and-origin account supported by the documented facts, and failing to separate the technician's factual observations from conclusions about fault.
Candidates blur the technician's role with the investigator's. They either overstate conclusions ('the appliance was defective') or under-document facts (burn patterns, first-fuel, protection failures) that a subrogation reviewer needs.
What to do instead
Record objective observations: origin area, burn and char patterns, first material ignited, ignition source as observed, and any evidence of a failed product or protection system, each tied to photographs and measurements. Leave causation opinions to the qualified investigator and note when one should be engaged.
