P01
Capture at the source
The most effective dust is the dust that never escapes the machine enclosure, hood, tool shroud, sanding head, transfer point, or cleanout connection.

Dust collection planning · combustible dust management
Design the complete extraction system around people, machines, fire risk, and uptime.
Titan helps manufacturers audit, refit, expand, and deploy dust collection systems around real machines, actual simultaneous demand, source capture, duct routing, filtration, discharge, return air, make-up air, controls, housekeeping, maintenance, fire and explosion protection, and the production consequences of downtime.
01Capture · Convey · Filter · ProtectField Manual
Cleaner production and safer uptime
A powerful collector can still underperform. The complete network determines what the shop experiences.
Dust collection is a connected production and life-safety system. Capture begins at the machine, then depends on branch design, duct routing, fan performance, filtration, discharge, controls, make-up air, return-air decisions, fire and explosion protection, housekeeping, maintenance, and how operators actually run the shop.
WorkSafeBC guidance emphasizes a systematic, long-term combustible wood-dust management program rather than relying on one piece of equipment. Titan’s public-facing planning framework helps organize the machine, airflow, installation, maintenance, and operational questions while qualified professionals, authorities having jurisdiction, contractors, manufacturers, and insurers determine the requirements for the specific facility.
P02
Design the complete system
Collector capacity, fan curve, duct network, machine ports, gates, make-up air, discharge, filtration, controls, fire protection, and operating sequence must be evaluated together.
P03
Use actual simultaneous demand
The design condition is the set of machines that can truly operate together—not the sum of every nameplate port and not an optimistic assumption that only one machine will run.
P04
Maintain transport conditions
Branches and mains must be sized, routed, gated, and balanced so the intended material remains conveyed without excessive pressure loss, wear, noise, or deposits.
P05
Treat combustible dust as a program
A collector is only one control. Housekeeping, ignition control, inspections, training, management of change, emergency response, and qualified review belong in the program.
P06
Separate incompatible dusts
Wood, plastic, composite, and combustible metal dusts should not be mixed casually. Material compatibility, reaction risk, collector type, and disposal method require qualified review.
P07
Trend condition, not just alarms
Differential pressure, airflow, fan load, gate status, bin level, filter-cleaning activity, spark events, and downtime trends reveal degradation before the system fails.
P08
Plan for maintenance access
Filter replacement, explosion-protection inspection, duct cleanout, fan service, bin removal, rotary-valve service, sensor testing, and firefighting access require space and safe isolation.
The dust stream changes with the machine, material, and operation.
A nester, beam saw, edgebander, wide-belt sander, timber CNC, handheld tool, composite router, and metal-finishing process do not create the same pickup, conveyance, filtration, fire, or disposal problem.
01
CNC routing and nesting
High chip volume mixed with fine spoilboard and panel dust. Extraction must follow changing toolpaths, enclosure leakage, hood position, vacuum-table condition, and the volume created during surfacing or pocketing.
02
Beam and panel sawing
Main-blade and scoring dust, chips, stack effects, moving saw carriages, pressure-beam leakage, waste handling, and multiple extraction ports create a highly dynamic collection requirement.
03
Edgebanding and squaring
Pre-mill chips, trim waste, fine dust, scraper residue, buffing lint, glue-area cleanliness, and machine enclosure geometry require branch-by-branch attention.
04
Wide-belt and brush sanding
Large volumes of fine dust demand effective source capture, filter-area planning, fire-risk controls, clean air monitoring, and disciplined housekeeping around concealed surfaces.
05
Solid wood and moulding
Planer, moulder, shaper, tenoner, rip-saw, and profiling processes create variable chips and dust influenced by species, moisture, feed, cutter geometry, and extraction hood design.
06
Timber and mass timber
Large sections and aggressive machining produce high chip mass, long duct runs, deep pockets, large hoods, and intermittent peaks that can stress undersized discharge and storage systems.
07
Hand tools and local stations
High-vacuum source capture may suit routers, sanders, trim tools, benches, and isolated processes where low-volume/high-velocity pickup is more appropriate than a large low-vacuum branch.
08
Plastics and composites
Dust may be fibrous, static-prone, abrasive, heat-sensitive, or chemically different from wood dust. Material testing and compatibility review may change filtration and fire-protection requirements.
09
Combustible metals
Aluminium, magnesium, titanium, and other combustible metal dusts can require dedicated collection strategies and must not be routed into a wood-dust system without qualified engineering and code review.
10
General housekeeping
Floors, machine tops, beams, cable trays, lights, ledges, roof structure, and hidden spaces need an approved cleaning method that does not simply redistribute combustible dust.
The ten connected parts of a complete dust system.
Weakness in any one layer can create poor capture, excessive energy use, filter problems, dust accumulation, downtime, or a protection gap.
A01

A10
Housekeeping system
Fixed vacuum network, mobile approved vacuums, cleaning tools, overhead access, waste handling, schedules, inspections, and records.
The protection objective
Capture the fuel, control ignition, and prevent a local event from propagating through the connected system.
Combustible dust planningThe current NFPA 660 standard consolidates the former general and industry-specific combustible-dust standards, including the former wood-processing standard. In British Columbia, the current provincial fire-code framework and WorkSafeBC requirements also apply. Project-specific compliance requires qualified analysis and authority review.
Z01
Machine generation zone
Where dust and chips are created. Review hot surfaces, friction, tool failure, foreign material, static, and source capture.
Z02
Transport duct zone
Where a spark, ember, flame front, or pressure wave may travel. Review detection, extinguishment, isolation, wear, deposits, and cleanouts.
Z03
Collector protection zone
The dust collector is a primary confinement point. Location, venting or suppression, isolation, structural effects, and access require engineered coordination.
Z04
Discharge and storage zone
Bins, silos, rotary valves, conveyors, compactors, and waste rooms can accumulate fuel and introduce friction, heat, or blockage.
Z05
Return-air zone
Any air returned indoors requires filtration, monitoring, isolation, and fire/explosion protection appropriate to the dust and jurisdiction.
Z06
Housekeeping accumulation zone
Floors, rafters, suspended ceilings, cable trays, lights, machine tops, and concealed ledges can support damaging secondary events.
Z07
Ignition and hot-work control zone
Hot work, smoking, heaters, electrical equipment, static, overheated bearings, and maintenance activity require controlled permits and separation.
Z08
Emergency access and response zone
Fire-department access, vent discharge areas, emergency stops, isolation points, egress, water supply, and incident plans must remain usable.
01
Define the planning scope
Clarify the materials, machines, shifts, production goals, complaints, expansion plans, fire history, dust types, current controls, and decisions the project must support. Establish whether the review covers one machine, one cell, the full shop, a new building, or an existing-system refit.
QuestionsWhat must improve: capture, cleanliness, worker exposure, fire risk, capacity, uptime, energy, filtration, or expansion readiness?
BoundariesBuildings, machines, materials, ducts, collectors, waste systems, controls, and jurisdictions included.
SuccessAcceptance measures for airflow, housekeeping, availability, alarms, maintenance, and production support.
02
Inventory dust-generating equipment
Build a machine schedule that records process, material, extraction ports, hood arrangement, manufacturer information, operating pattern, expected simultaneity, chip or fine-dust character, current complaints, and future equipment. Include hand tools, cleanup stations, transfer points, waste equipment, and infrequently used machines that can still affect the network.
Machine dataMake, model, process, port sizes, hood movement, enclosure, and manufacturer requirements.
Operating profileShift schedule, typical combinations, peak combinations, campaigns, and seasonal demand.
Dust profileChip mass, fine fraction, abrasive content, moisture, static tendency, and combustible characteristics.
03
Survey the current state
Observe the shop while representative machines are running. Look for visible escape, dust curtains, deposits near hoods, plugged hoses, open gates, damaged duct, worn elbows, flex-hose collapse, leaking bins, filter-cleaning activity, fan sound, weak capture, and dust accumulation on elevated or hidden surfaces. Interview operators and maintenance staff about recurring problems and workarounds.
Capture evidenceWhere dust visibly escapes, settles, or re-enters the work area.
System conditionLeaks, damaged components, deposits, corrosion, wear, vibration, and blocked access.
Work practicesGate use, cleanup methods, bin emptying, alarm response, filter service, and temporary modifications.
04
Characterize the dust and hazards
Identify the actual materials entering each collection stream and obtain representative testing where required. Published values can support screening, but dust characteristics can change with material, process, particle size, moisture, additives, coatings, and contamination. Determine whether separate streams are required for combustible metals, plastics, composites, hot processes, or incompatible materials.
Material recordWood species, panels, coatings, plastics, metals, composites, abrasives, and contaminants.
Hazard dataRepresentative combustibility and explosibility information obtained through qualified analysis.
CompatibilityStreams that may share equipment and streams that must remain separated.
05
Build the airflow demand model
Develop the design operating scenarios and total the branches expected to run together. Use machine and hood requirements, measured performance, system pressure losses, control sequence, gate logic, and planned growth. Avoid sizing from port diameter alone or assuming every gate is either permanently open or perfectly controlled.
Operating scenariosNormal shift, peak production, cleaning mode, maintenance mode, and future phase.
Demand modelRequired airflow and system resistance for each scenario, verified by qualified design.
Control logicWhich gates, fans, and collectors operate together and how status is proven.
06
Optimize source capture
Improve capture before increasing fan power. Review hood placement, enclosure leakage, tool shroud position, pickup direction, capture distance, skirt condition, machine pressure zones, transfer-point containment, and whether moving heads or carriages remain connected through the full cycle. Poor capture can waste large airflow while leaving the source uncontrolled.
Capture pointPlace collection where particles are generated and moving.
ContainmentUse enclosure and controlled openings to reduce the air volume required.
VerificationObserve representative cycles, difficult toolpaths, loading, unloading, and cleanout conditions.
07
Develop the duct network
Lay out branches and mains to support transport, low pressure loss, service access, wear control, and future change. Review branch entry, transitions, elbows, vertical and horizontal runs, flexible hose, supports, cleanout access, blast or automatic gates, balancing, static control, and the consequences of closing or opening different machines.
RoutingShortest practical path with accessible cleanouts, supports, and service zones.
DurabilityWear-resistant components where abrasive chips or high velocity create erosion.
BalanceBranch and main behavior across every approved operating scenario.
08
Select separation and filtration
Match collector style and filter media to particle distribution, dust loading, airflow, operating hours, temperature, moisture, static, disposal method, emissions target, and fire-protection strategy. Review filter area, air-to-media loading, cleaning method, differential pressure range, hopper design, and how cleaning interacts with production.
SeparationCyclonic or mechanical pre-separation where it improves the total system.
FiltrationBag or cartridge media selected for the dust and manufacturer-rated application.
CleaningReverse air, pulse, shaker, or other manufacturer method with condition monitoring and service access.
09
Plan building-air balance
Decide whether filtered air is exhausted outdoors or returned indoors through an approved system. Evaluate make-up air, heating or cooling loss, building pressure, door operation, process ventilation, worker comfort, fire and explosion isolation, monitoring, and local authority requirements. A return-air decision is a life-safety and indoor-air-quality decision, not only an energy calculation.
Air balanceExhausted volume, make-up air, building pressure, and seasonal operating conditions.
Return-air protectionFiltration, monitoring, isolation, diversion, and shutdown strategy where permitted.
EnergyFan control, automatic gates, variable speed, heat loss, and realistic operating schedule.
10
Engineer fire and explosion protection
Coordinate a qualified dust hazard analysis and code review. Depending on the dust, equipment, location, and jurisdiction, the protection concept may include spark detection, extinguishment, abort or diversion, deflagration isolation, explosion venting, flameless venting, suppression, rotary valves, fire detection, sprinklers, shutdown interlocks, hazardous-location electrical classification, and emergency-response provisions.
PreventionControl ignition sources, deposits, overheating, static, foreign material, and maintenance hazards.
ProtectionLimit pressure, flame propagation, and fire spread using engineered and listed systems.
ResponseAlarm, shutdown, evacuation, fire-department access, inspection, and post-event recovery.
11
Design collected-material handling
Confirm how chips and dust leave the collector and how storage capacity matches production. Review hopper slope, rotary valve, screw or chain conveyor, drum, bin, silo, compactor, briquetter, level sensor, blockage detection, truck access, weather protection, housekeeping, and disposal schedule. A good collector can still fail when its discharge system plugs or overfills.
CapacityPeak production, collection efficiency, density, pickup schedule, and contingency storage.
Fault detectionHigh level, conveyor jam, rotary-valve fault, bin position, and discharge confirmation.
LogisticsSafe removal, transport, disposal, recycling, fire separation, and access.
12
Build the control and monitoring plan
Define what the system must prove before machines run and what conditions require warning or shutdown. Useful signals may include fan status, airflow or pressure, gate position, differential pressure, filter-cleaning status, motor load, vibration, bin level, discharge operation, spark or temperature events, fire-protection status, and return-air condition.
PermissivesConditions required before connected production equipment is released.
AlarmsClear priorities, setpoints, delays, notification paths, and operator responses.
HistoryTrend data that helps maintenance distinguish a gradual restriction from a sudden fault.
13
Create the housekeeping program
Define approved methods, tools, routes, frequencies, responsibilities, and inspection criteria for production areas, collector rooms, elevated surfaces, hidden ledges, cable trays, beams, lights, ducts, machine tops, pits, and waste areas. Routine blowdown can suspend and redistribute dust; WorkSafeBC specifically warns about compressed-air cleaning of combustible dust.
MethodsApproved industrial vacuuming, fixed-vacuum cleaning, sweeping or wet methods where suitable, and controlled exceptions.
ZonesRoutine areas, high-generation areas, overhead areas, concealed spaces, and incident cleanup.
RecordsInspection, cleaning completion, deficiencies, photos, corrective actions, and reinspection.
14
Develop preventive maintenance
Convert the system into inspectable assets with manufacturer-based tasks and intervals. Include hoods, hoses, ducts, supports, gates, fan, bearings, drive, filter-cleaning system, media, differential pressure, hopper, rotary valves, conveyors, bins, explosion protection, spark systems, sensors, controls, fire systems, grounding and bonding, and return-air monitoring.
RoutinePer-shift and weekly visual checks, alarms, bin level, leaks, capture, and housekeeping.
Planned serviceFilter, fan, drive, bearings, duct wear, protection devices, sensors, and electrical inspections.
SparesFilter media, seals, hoses, sensors, valve parts, belts, bearings, and critical control components.
15
Commission and prove the complete system
Commissioning should verify installed components, rotation, controls, gate sequence, alarms, filter cleaning, discharge, fire and explosion protection, airflow and pressure at representative machines, building pressure, return-air behavior, housekeeping connections, documentation, and operator response. Test normal production, peak combinations, startup, shutdown, fault, and recovery conditions.
Pre-startDrawings, permits, qualified inspections, utilities, protection systems, access, and training ready.
PerformanceMeasured airflow, pressure, capture, differential pressure, noise, emissions, and simultaneous operation.
AcceptanceOpen items, owners, due dates, baseline readings, manuals, and approved operating scenarios.
16
Operate, audit, and improve
Review the system whenever machines, materials, processes, ducting, filters, controls, production schedules, buildings, or fire-protection assumptions change. Use trend data, housekeeping findings, downtime, filter life, energy, spark events, capture complaints, and maintenance history to refine the system before a small deviation becomes a production or safety event.
Management of changeFormal review before new machines, new dusts, altered gates, duct changes, or return-air changes.
Audit cadenceScheduled review of performance, fire protection, housekeeping, maintenance, records, and training.
Growth planReserved airflow, physical space, controls, discharge capacity, and phased infrastructure.
Cleaning and maintenance cadence.
Actual intervals must follow manufacturer instructions, dust generation, operating hours, condition, hazard analysis, and applicable regulation. The schedule below is a planning framework, not a universal service interval.

QUARTERLY
Qualified service
Functional testing of controls and interlocks; selected airflow verification; filter and discharge inspection; fan vibration review; protection-device inspection per manufacturer requirements.
ANNUAL
Qualified team
Comprehensive system audit, hazardous-location and fire-code review as applicable, dust-management program review, emergency exercise, training refresh, and management-of-change validation.
Composite downtime case studies: what small deviations can become.
CASE 01
The filter that became the bottleneck
A growing CNC cell ran acceptably after installation, but differential pressure climbed gradually as fine spoilboard dust loaded the media. Operators compensated by opening more gates and extending cleanup. Capture weakened, cabinets accumulated dust, and the collector required an emergency shutdown during a production week.
Proven responseTrend differential pressure, establish clean and loaded baselines, verify cleaning performance, stock critical media, and plan replacement before the process leaves its approved operating window.
CASE 02
The all-gates-open energy tax
A central system was operated with nearly every manual gate open because the shop had no ownership rule. The fan consumed full power while the critical sander branch underperformed. Deposits appeared in low-use horizontal branches and machine operators assumed the collector was undersized.
Proven responseDefine operating scenarios, use disciplined or automatic gate control, verify branch performance, balance the system, and review variable-speed control against the approved demand model.
CASE 03
The worn elbow and hidden leak
A high-chip-volume branch used a tight elbow at a wear point. The outside looked normal until the wall thinned through, releasing dust behind equipment. Cleanup increased, airflow dropped, and the repair required an unplanned shutdown and difficult access work.
Proven responseIdentify abrasive wear zones, use suitable fittings, provide inspection access, include thickness or condition checks, and keep repair components available.
CASE 04
The full-bin shutdown
A discharge conveyor fault stopped material removal while the collector continued running. The high-level alarm was unreliable, the hopper filled, filter cleaning became ineffective, and the cell was down until material could be removed safely and the discharge equipment repaired.
Proven responseProve discharge operation, use reliable level and fault monitoring, interlock continued operation where appropriate, inspect the full discharge route, and define contingency capacity.
CASE 05
The fire path through connected ducting
A small ignition event in process equipment entered the collection network. Without a fully coordinated detection and isolation strategy, the connected duct system created a path toward other equipment and occupied areas. The resulting investigation and repairs created extended downtime far beyond the initial machine.
Proven responseUse a qualified hazard analysis to determine prevention, detection, extinguishment, isolation, venting or suppression, shutdown, and emergency-response requirements for the actual dust and system.
CASE 06
The new machine that changed everything
A new beam saw was connected to an existing collector using available duct space. The branch added pressure loss, altered the balance of several existing machines, and increased peak discharge volume. The saw ran, but two legacy machines lost capture and housekeeping demand rose across the shop.
Proven responseUse management of change: update the demand model, recalculate the network, confirm fan and filter capacity, review discharge and protection systems, and recommission all affected operating scenarios.
