Clean spaces for critical equipment
Dust is a slow enemy in a data hall. It rides in on shoes and cardboard, settles on intakes and cable trays, and gets pulled through servers by the cooling system. Keeping it out of the white space protects the equipment and makes an audit or customer tour go smoothly. The rest of the building matters too: the security lobby, the operations office, the break room and the restrooms used by technicians around the clock.
Ora Commercial Cleaning supports data center operators with both kinds of work. Routine janitorial service covers the offices and support areas, and controlled-environment cleaning of white space, raised floors and under-floor areas is done only to the operator’s written procedures.
Data center markets in our area
Data centers run across our service area: colocation campuses around Sacramento and Rancho Cordova, data halls in Sparks and Reno, and colocation and enterprise sites around San Jose and Fremont. Each one is cleaned to the operator’s written procedures.
White space to the operator’s procedures
Before any crew enters a data hall, the operator’s method statement sets the rules: who may enter, which aisles and cages are included, which tools and products are approved and when work can happen. Ora follows that document exactly. Cleaners gown as required, with shoe covers, gloves and sometimes hair covers or lab coats, and pass over sticky mats at the door.
Work moves from top to bottom and from clean areas toward the exit. Cabinet tops, cable trays and overhead ladders within reach are dusted with low-lint cloths and HEPA-filtered vacuums. Racks, cabinet faces and the equipment inside are left untouched unless the operator’s procedure says otherwise.
Raised floors and under-floor plenums
Raised floor tiles are vacuumed with HEPA equipment and damp wiped with approved, low-residue solutions, never wet mopped. Where the operator schedules sub-floor cleaning, tiles are lifted a few at a time following its sequence, the plenum is vacuumed to remove dust and debris, and each tile goes back in its place before the next one comes up.
Perforated tiles, cold-aisle containment doors and panels, and the room’s perimeter get the same low-lint care. Cardboard and packing waste from equipment installs are collected and removed through the route the operator approves, since loose packing material is a major dust source.
Access, escorts and accountability
Data centers run strict access control, and Ora works inside it. Crew names are submitted in advance for badge or visitor approval, cleaners sign in at the security desk, and white space work happens under escort when the operator requires it. Every cleaner is background-checked before being put forward for a site.
Supervisors inspect completed work against the operator’s checklist and report to the facility manager. Keys, badges and access cards are tracked to the person, and any change in crew is cleared with the site before that person arrives.
Offices, support rooms and loading areas
Outside the white space, the building runs like a busy office with long hours. Ora cleans the security lobby, NOC and operations offices, conference rooms, break rooms, locker rooms and restrooms, and keeps the shipping and receiving area swept so cardboard dust stays out of the corridors. A day porter can cover a 24-hour campus between night visits.
Hard floors in corridors and staging rooms can be scrubbed and refinished through commercial floor care, and warehouse-style support areas fit within our industrial cleaning routine.
What shapes the price
Four things drive the price: the square footage of offices and support areas with the size and number of data halls included; how often raised floors and plenums are cleaned; gowning and escort requirements; and the allowed work windows, plus any porter coverage. Your vendor file gets Ora’s certificate of insurance before the first shift, and workers’ compensation covers every crew member on site.
A site walk with the facility manager, guided by the operator’s procedures, sets the task list and a clear price for both the routine work and the periodic white space cleaning.
A few useful answers
Common questions.
Does Ora clean inside the data hall?
Yes, to the operator’s written procedures, with gowning, low-lint materials, HEPA vacuums and escorted access where the site requires it.
Can raised floor plenums be cleaned?
Yes. Tiles are lifted in the operator’s sequence, the under-floor space is vacuumed and each tile is replaced before the next is lifted.
Will cleaners touch our servers or racks?
Only if your procedure allows it. Otherwise racks, cabinets and equipment are left alone and cleaning stays on floors, trays and surrounding surfaces.
How are crew members cleared for site access?
Names go to your security team in advance for badge or visitor approval, and every cleaner is background-checked before being submitted.
