Industrial woodworking and wood-panel plants: what a drone documents (ICPE heading 2410), price
A wood-processing plant — an industrial joinery, a panel manufacturer, a furniture workshop — carries a hazard combination few other industries match: vast production-hall roofs, cubic metres of raw timber and finished goods stored in the open, and wood dust that is both a health hazard and an explosion hazard. That risk sits under a multi-tier classified-installation framework distinguishing the processing workshop, the panel plant covered by the EU industrial emissions directive, and wood-preservation treatment. Here is what those headings require, what a drone campaign concretely documents on this kind of site — staying strictly outdoors — and what it never measures.
Published on 22 September 2026, reviewed on 22 September 2026 — regulations in force as of September 2026.
Three ICPE headings, one shared hazard: wood dust
A woodworking workshop — secondary sawing, machining, sanding, gluing, panel or furniture assembly — falls under ICPE heading 2410, "working of wood and similar combustible materials". The regime depends solely on the installed power of the fixed machinery: above 50 kW and up to 250 kW, the installation requires declaration; above 250 kW, it moves into registration. This three-tier split comes from decree n° 2014-996 of 2 September 2014, backed by an order of the same date setting the registration regime's general requirements — before that text, the authorisation threshold sat at 200 kW. An industrial joinery running several machining lines crosses that threshold quickly.
Above that first tier, manufacturing wood-based panels — oriented strand board (OSB), particle board, fibreboard — falls under a separate heading, 3610, once production capacity exceeds 600 m³ per day: the plant then moves under authorisation and the EU's industrial emissions regime (the IED directive), with a duty to apply the best available techniques set out in the sector's reference document. A handful of French sites — on the order of ten — exceed that threshold. A third heading, 2415, specifically governs the application of wood-preservation products (fungicide or insecticide treatment by dipping or autoclave), with its own registration regime introduced by an order of 2 March 2023.
This regulatory triptych covers neither roundwood at a sawmill, dealt with in our guide on log pile volume by drone, nor wood-energy fuel in stockpiles, covered by our guide on thermal monitoring of wood-chip stockpiles: it targets the processing plant itself, where wood changes shape and the dust generated by sawing, sanding and planing becomes the central issue.
What the drone documents: roofs, outdoor storage and roof-mounted extraction ductwork
The roof of the production halls remains the first target: several thousand square metres of cladding, often built up through successive extensions, where the same defects are sought as on any industrial building — cracked sheets, loosened fixings, gutters clogged by wood fines that settle continuously on nearby roofs. The principle matches that set out for logistics building roof inspection, and many of these halls, built before 1997, call for the same asbestos-cement survey described in our guide on asbestos roofing before works.
Second target: the outdoor storage yards. A panel plant or an industrial joinery permanently holds raw timber awaiting processing and finished goods — panels, framing components, packaged furniture — in outdoor yards whose volume drives both the inventory value of the stock and an insurer's exposure to fire risk. Photogrammetry produces a georeferenced volume of these piles in a few minutes, on the same principle as the log-pile cubage cited above, but applied here to processed timber stacked more regularly.
Third, more technical target: the dust-extraction network visible on the roof — ducting, cyclones, buffer silos for sawdust and shavings that often feed an adjacent biomass boiler. The drone photographs its outer condition (corrosion, fixings, visible explosion-relief panels) exactly as described in our guide on industrial chimney and silo inspection by drone: a surface record, never a check of the network itself.
The honesty clause: not dust concentration, not its explosivity, not worker exposure
The honesty clause. No aerial camera measures an airborne dust concentration, a minimum ignition energy or an explosivity index: those figures are determined in a laboratory, on a collected sample, never from imagery. A team from the Faculty of Wood Sciences and Technology at the Technical University in Zvolen (Slovakia) published a full characterisation of spruce sanding dust in 2025, in the journal Forests: an average particle size of 73.2 × 38 µm, 71% of the dust mass falling between 10 and 100 µm, and the three risk dimensions it documents — health (the International Agency for Research on Cancer classifies wood dust as carcinogenic for the nasal cavities and sinuses), fire and explosion (see the study). All three dimensions are measured exactly as in that study — sampling, sieving, laboratory testing — never from a drone.
Second limit: the drone never enters the inside of a silo, a cyclone or an extraction duct classified as ATEX zone 20, 21 or 22 under the explosive-atmosphere directives — the same limit set out in our guide on industrial chimneys and silos. Interior inspection of those volumes stays reserved for an Ex-certified operator, on an empty, ventilated, isolated silo. Third limit: workers' actual exposure to wood dust — measured in milligrammes per cubic metre of breathed air and compared against the regulatory occupational exposure limit — is a matter for occupational health services and individual sampling campaigns, something neither a visible-light nor a thermal camera can document from a distance.
Who commissions this service and 2026 prices
Demand comes from panel manufacturers and industrial joineries preparing a technical shutdown or a major-maintenance budget, from furniture manufacturers concerned about the value exposed in their outdoor yards, from property-damage insurers putting figures on a fire risk considered high for this kind of site, and from ATEX consultancies preparing an explosion risk assessment who need a reliable overall plan of the roof-mounted equipment. Ranges observed in France in 2026, excl. VAT:
| Service | Observed price (excl. VAT) |
| Hall roofs, orthophoto and high-resolution visual inspection | €800 to €1,600 |
| Photogrammetric volume of outdoor storage yards (raw timber and finished goods) | €400 to €900 |
| Additional pass over extraction ductwork, cyclones and roof silos | €300 to €600 |
| Full campaign (roof + storage + extraction network) | €1,400 to €2,800 |
These amounts cover the flight, processing and report; they exclude the explosion risk assessment, the statutory interior check of the extraction network, and occupational exposure monitoring, which remain the responsibility of the ATEX consultancy, the inspection body and occupational health services. Request a quote stating the roof area, whether outdoor storage needs a volume survey, and whether the site falls under heading 2410, 2415 or 3610.
