Critical Environment Cleaning

Dust Free Critical Environment Solutions for Sensitive Spaces

Critical Environment Cleaning

Environmental dust in a critical environment:

In a 5 Micron clean scenario 8 Tn dust particles can easily exist in a space of one cubic meter space theoretically. To achieve compliance against ISO 14644 Class 8: 2015, One needs to control and reduce the dust particles density below 3.52 Mn in a space of 1 Cubic meter using better air scrubbing and cleaning mechanisms accompanied by periodic air particles and IAQ testing.

Ill effects of dust contamination:

An uncleaned and contaminated data center will slowly build up dirt and debris until it eventually starts to impact equipment reliability, customer perception and eventually creates a fire risk, thus gravely impacting your IT Investment.

■ Overheating of components caused by electrostatically charged dust sticking to electronic components and insulating them so they are unable to be cooled.

■ Short circuiting of components caused by conductive dust particles.

■ Short circuiting of components caused by deliquescent dust. (Deliquescent and electrostatic problems can, however, be reduced by keeping the computer room’s relative humidity within the prescribed levels of 41.9 – 59% RH.)

■ Damage to disk drive heads.

■ Damage to optical fibre connector interfaces.

■ Reduction in CRAC unit efficiency, as dust acts as an insulator, impeding airflow through cooling systems, which can lead to increased operating temperatures inside the critical rooms.

■ Increased energy consumption – as the CRAC unit filters get choked due to dust contamination, the machine must work overtime to enforce the same amount of cooling effect on the given space.

Solution

Periodic cleaning of the critical environment depending upon the footfall is necessary as per ASHRAE recommendations.

Cleaning above 1.8 Meters height

Lights, overhead power and fiber cable trays, Hot and cold isle separators, any fixtures and fitments taller than the racks. VESDA pipes, Gas suppression system pipes, Rack top covers, Cold isle top envelope covers, Overhead Plenum, if any, etc.

Cleaning above raised floor level

False flooring tiles top, vertical wall surface finishes, racks and other equipment exterior surfaces , Cold and Hot isle separator partitions and doors, Grill vent floor tiles, epoxy floor, doors, electric panels, white goods, loose items, etc.

Cleaning below false floor level

Cable trays, cables, treated concrete floor, epoxy floor, false flooring tiles bottom, frame network of the false floor tiles. Wall surfaces, electrical fixtures and fittings

Cleaning below concrete floor level

Cleaning of the trench walls, clearing it free of debris, ensuring anti pest barriers are in place , vacuuming of the entire place.

Execution:

■ Avoid safety risks and minimise disruption of normal room functioning, CTS initially completes a Risk Assessment and defines procedures prior to commencing work.

■ CTS provides a site-specific Safe Work Method Statement (SWMS) and Risk Assessment before beginning work.

■ A customer briefing is conducted to discuss power connection preferences, isolation of detection systems (VESDA, Pressure and Moisture) and maximum number of tiles to be lifted at one time, as well as all WHS issues.

■ Only electrical equipment dedicated to cleaning IT environments is used which is tagged and assessed current.

■ A dry clean is performed using low decibel vacuums equipped with HEPA filters (efficiency rating 99.97% at 0.3 microns).

■ Proven proprietary CTS cleaning techniques focus on minimal and controlled use of moisture, avoiding contact with smoke detectors, moisture sensors, cables, and power points.

■ CTS cleaners implement risk controls such as displaying appropriate barricades and warning signs where overhead work is taking place.

■ CTS uses non-conductive fibreglass platform ladders for added worker safety.

■ No moisture of any form is used; CTS techniques employ specially treated ESD disposable cloths which trap and remove loose dust.

■ Specific problems such as adhesive residues and scuff marks are tackled with cleaning chemicals whose efficacy is regularly reviewed and assessed.

■ ESD-safe precautions are always taken, including grounding of the CTS cleaner before starting the work.

■ An ESD-safe, HEPA-filtered vacuum and attachments are used to remove dust from the interior.

■ ESD safe tools and tackles are used while cleaning. Noncorrosive, PH neutral, ESD deterrent cleaning agents are used.

Key Parameters	Competition	COLO TechXpert	How are we better
Cleaning approach	Piece meal type – Only interested in the cleaning of that specific area	Holistic type – with environmental dust management as a key driving force behind the endeavour.	We will advise and suggest ways to Deter, Detect, Deny, Delay, and Defend the Critical environment from environmental dust accumulation and related hazards.
Method of Execution	More manpower intensive cleaning	More mechanized cleaning; optimized use of tools, tackles, and consumables.	Multi-fold increase in cleaning efficiency. Consistent cleaning output with excellent results due to optimized RPM, suction power, and UV light intensity.
Execution time	Remarkably high due to dependency on physical labor	Usage of ergonomic tools, tackles, and a strict sequential cleaning process avoids duplicate actions.	Results in a 250% quicker turnaround time for the given work area.
HSE	Lack of awareness about safe practices to follow.	Adherence to HAZOP and implementation of mitigation measures like pre-site audits, toolbox talks, ensuring relevant PPE, ergonomic tools, and non-corrosive chemicals.	Safety-first approach ensures safety of personnel, premises, and the environment.
Types of cleaning agents used	Corrosive and non-ESD deterrent by nature.	Non-corrosive, pH-neutral, ESD deterrent cleaning agents from Johnson Diversey.	Noncorrosive, ESD deterrent coating on the floor increases system reliability.
Dedicated training and continuous up-skilling program	Generic and old training methods.	Specific training programs for Data Center cleaners, technical area cleaners, and critical environment supervisors with a competency matrix evaluation and correction mechanism.	Ensures faster turnaround time and maintains safety and excellence in cleaning operations.
Top Level cleaning	No mechanism to address airborne dust from top-level cleaning.	Standardized approach to capture and remove airborne dust from top-level surfaces.	Point of origin dust capture results in a more pristine environment with less airborne dust.
HVAC filter cleaning	Does not support	Conducts pre and post-cleaning of HVAC air filters as per OEM recommendations.	Prevents reintroduction of dust inside the critical environment, improving energy efficiency.
Sub floor cleaning	Normal vacuuming	Industrial vacuum machines, UV light-based vacuuming of trays/cables in the plenum.	Ensures high-quality cleaning.
