Data Center Cleaning Training Modules
Five modules covering how our technicians think about work inside a live data hall — contamination pathways, the raised-floor plenum, hazard planning, tool and chemical selection, and how standards frameworks actually apply. Filmed step-by-step demonstrations of each procedure are currently in production; the written modules below reflect the procedures our crews follow.
Training summary only. Facility-specific MOP/SOP, manufacturer requirements and authorized site procedures always control.

An illustrated walk-through of the source → path → receptor model: how particles enter a data hall, how they travel, and which controls interrupt them before they reach equipment intakes.
Filmed step-by-step demonstrations of this procedure are currently in production. The written module below reflects the procedure our technicians follow.
Training summary only. Facility-specific MOP/SOP, manufacturer requirements and authorized site procedures always control.
Scenario question: a delivery door has been propped open near the white-space vestibule during a scheduled clean — what do you control first?
Read the text summary of Contamination Control
Contamination control begins before any cleaning task starts. The objective is to stop particles at the source, manage the path they travel, and protect the receptor — the operating equipment.
Sources include outside air infiltration, packaging and delivery activity, people and clothing fibers, tools, and systemic sources such as cable jacket dust and deteriorating understructure coatings.
Path controls include zoning with defined hand-off points, tacky mats and dedicated footwear, keeping doors closed to preserve pressurization, staging tools outside the clean zone, and using capture-at-source HEPA filtration rather than displacing dust.
Receptor protection means never disturbing airflow into rack intakes, never contacting energized equipment, and verifying the space against its particulate target after work is complete.
The sequence is always the same: source, then path, then receptor. Cleaning that skips containment simply moves contamination somewhere else in the facility.

Underfloor Cleaning: The plenum is operational space
Why a raised-floor plenum is treated as live infrastructure rather than an ordinary floor: airflow obstruction, concealed cabling, energized hazards, and sequenced tile-lift discipline.
Filmed step-by-step demonstrations of this procedure are currently in production. The written module below reflects the procedure our technicians follow.
Training summary only. Facility-specific MOP/SOP, manufacturer requirements and authorized site procedures always control.
Scenario question: a lifted tile reveals a dense cable bundle resting on debris directly upstream of a perforated tile — what changes about your approach?
Read the text summary of Underfloor Cleaning
The sub-floor plenum is the cold-air path in a downflow-cooled hall. Debris underneath the floor is directly upstream of every rack intake, so underfloor work is an airflow task before it is a cleaning task.
Underfloor debris can obstruct airflow, raise supply temperatures, and increase fan energy. It also conceals cabling, whips, and energized components that must not be contacted.
Tiles are lifted in small, sequenced clusters so plenum pressurization stays inside setpoint. Open positions are marked, guarded, and closed before the crew moves on.
Cleaning uses sealed HEPA filtration with dissipative hoses, wiping of pedestals and stringers with electronics-appropriate chemistry, and no dry sweeping or air blow-down.
Findings such as damaged cable jackets, abandoned cable, corrosion, or water residue are documented and escalated rather than disturbed. A raised floor is never treated like an ordinary floor.

Risk Mitigation: Plan the failure path
A hazard → control → verification framework for mission-critical work: identifying what could be touched, blocked, tripped, contaminated or unintentionally activated before a task begins.
Filmed step-by-step demonstrations of this procedure are currently in production. The written module below reflects the procedure our technicians follow.
Training summary only. Facility-specific MOP/SOP, manufacturer requirements and authorized site procedures always control.
Scenario question: mid-task you find an unlabeled cable crossing your work zone — which stop-work trigger applies?
Read the text summary of Risk Mitigation
Risk mitigation begins by planning the failure path. Before the first tool comes out, the crew identifies what could be touched, blocked, tripped, contaminated, or unintentionally activated.
Each identified hazard is paired with a control: physical separation, barriers and signage, tool selection, sequencing around the change window, or simply excluding an area from scope.
Controls are then verified. Verification can be visual, photographic, instrumented, or a sign-off with the site engineer — but a control that is not verified is not a control.
Stop-work triggers apply when conditions change: unlabeled or damaged cabling, alarms, water or corrosion findings, equipment moved without notice, or any instruction that conflicts with the approved method statement.
The written MOP or SOP governs the task. When the field condition and the document disagree, work pauses and the document is updated through the authorized site process before work resumes.

Equipment + Chemicals: Select for the environment
How tooling and chemistry are chosen for controlled environments — sealed HEPA filtration, non-shedding materials, static control, surface compatibility, SDS review, and approval before application.
Filmed step-by-step demonstrations of this procedure are currently in production. The written module below reflects the procedure our technicians follow.
Training summary only. Facility-specific MOP/SOP, manufacturer requirements and authorized site procedures always control.
Scenario question: a general-purpose cleaner is on the cart but not on the approved list for this suite — what happens next?
Read the text summary of Equipment + Chemicals
Equipment in a controlled environment must do two things: capture particles rather than redistribute them, and control static risk while doing it.
That means sealed housings with rated HEPA filtration and a pre-filter, dissipative or grounded hoses and accessories, non-shedding wipes and mop heads, and no beater bars, blow-down, or dry sweeping.
Chemistry is selected for surface and electronics compatibility. Products are reviewed against the safety data sheet and the manufacturer's guidance for the surfaces present, applied to the wipe rather than sprayed toward equipment, and used at the specified dilution and dwell.
Anything not on the site's approved product list is not used. Approval comes before application, and substitutions go through the facility's change process.
Tool condition, filter status, and product lot information are recorded so the work can be reconstructed later from documentation.

ICRA / ISO-Aligned Procedures: Use the right framework
Where ISO 14644 cleanliness concepts and ICRA control concepts fit in data-center work — and the boundary between aligning with a framework and being certified to it.
Filmed step-by-step demonstrations of this procedure are currently in production. The written module below reflects the procedure our technicians follow.
Training summary only. Facility-specific MOP/SOP, manufacturer requirements and authorized site procedures always control.
Scenario question: a client asks whether your crew is “ICRA-certified” for their data hall — how do you answer accurately?
Read the text summary of ICRA / ISO-Aligned Procedures
ISO 14644 addresses cleanliness classification for controlled environments and provides a useful vocabulary for particulate targets and verification in a data hall.
ISO requirements apply to a project only when the owner, the contract, or the site specification adopts them. They are not automatically in force simply because a facility is a data center.
ICRA is a healthcare-oriented framework built around infection control during construction and renovation. Its control concepts — containment, barriers, traffic routing, and staged verification — can inform construction and renovation work inside a data center.
Applying those concepts does not make a data center project ICRA-compliant, and it does not make a crew or a facility “ICRA-certified.” The framework is healthcare-specific and certification is a separate matter entirely.
Alignment is not automatic certification. The governing documents remain the facility's own MOP and SOP, manufacturer requirements, and whatever standards the contract explicitly adopts.
