Critical Facilities Solutions is mainly focusing our attention on mission critical data centers, plant room and ancillary mission critical area decontamination and cleaning, as per our longstanding strategy, with the short-term addition of offices, common areas and ‘general’ ancillary areas, while the current Coronavirus (COVID-19) situation continues.  

In essence for a limited period CFS-US services will include decontamination and cleaning of touch point surfaces. 

Our standard operating procedures for cleaning will remain in place with the addition of pharmaceutical (ISO 14644-1 Class 5) hospital/medical grade cleaning materials and solutions being used in conjunction with our standard cleaning materials and solutions. 

Coronavirus (COVID-19)

In the absence of effective drugs or a vaccine, control of the Wuhan Novel Coronavirus (WN-CoV) relies on prompt identification, appropriate risk assessment, and site decontamination to minimize potential onward transmission. Personal protective equipment (PPE) and good infection control precautions are effective at minimizing risk but can never eliminate it. 

Coronaviruses are mainly spread by large respiratory droplets and direct or indirect contact with infected secretions. Large respiratory droplets are carried more than 20 feet away by sneezing, more than 6 feet away by coughing, and less than 3 feet away by breathing.  

Clearance of any airborne particles is dependent on the ventilation of the room. In rooms that have 12-15 air changes per hour, after about 20 minutes there would be less than 1% of the starting level once airborne particle generation has stopped.  

Decontamination and Cleaning Services 

Service Brief

The following guidelines and precautions cover cleaning and disinfecting areas exposed to confirmed or suspected COVID-19 cases in non-healthcare facilities.

This guidance is based on the current knowledge about SARS-CoV-2, the novel coronavirus which causes COVID-19, and evidence originating from studies on other coronaviruses.  

This SOP should be used by an onsite operations team when determining the actual requirements and risks of a specific situation.  

Regular cleaning and decontamination of surfaces can help prevent further infection. COVID-19 is a respiratory illness that spreads through droplets from an infected person’s cough or sneeze and by contact with contaminated hands, surfaces or objects. Depending on the temperature, humidity and nature of the material, current evidence suggests that COVID-19 may remain contagious on a surface for hours to days.  

Our environmental cleaning teams are trained and led by qualified and experienced team leaders who follow specific procedures, including establishing a risk assessment and method statement (RAMS). These strict decontamination procedures allow us to contain the cleaning with the least amount of impact across your business.  

In so far as is reasonably practical, CFS-US endeavors to do a full decontamination. However, due to the lack of information on coronavirus, we cannot guarantee that it has been eliminated completely from the site. 

The delivery of service includes:

  • Wiping and cleaning down all touch point surfaces with alcohol wipes and/or antibacterial cleaner 
  • Wiping and cleaning desks and desk hardware with alcohol wipes and/or antibacterial cleaner, including keyboards, desks, mice, screens, chairs, and solid furniture 
  • Wiping and cleaning flat surfaces and other touch point surfaces in all common and ancillary areas with alcohol wipes and/or antibacterial, including doors, walls, ledges, handles, door handles, light switches, lift buttons, staircase handrails etc.

CFS-US will thoroughly clean and decontaminate commonly used hand-touched surfaces and spray disinfectant, allowing contact time as specified by the manufacturers before wiping or ‘rinsing’, on all surfaces within the area being decontaminated.  

Additional Information 

  • Work to be completed in/or out of hours but require minimal occupation of staff at the time of delivery  
  • CFS-US will work through the building starting from the top down  

Cleaning Solutions, Equipment and Supplies   

  • CFS-US will make sure we have adequate solutions and supplies to complete the project. 

 o As the demand for cleaning is unprecedented at this time, we may need to utilize solutions that are available at the time of delivery but all COSHH and Safety sheets will be provided ahead of time and CFS-US will ensure the products are fit for purpose. 

  • CFS-US will separate disinfecting equipment from other routine cleaning equipment.  
  • CFS-US will use disposable equipment and supplies where possible, alternatively all equipment will be disinfected once returned to our premises ready for use again. 


Scientific studies are not yet available which confirm the most effective disinfecting agents to use against SARS-CoV-2, the virus that causes COVID-19, because it was discovered so recently.  

Scientists therefore are assuming that what works against other virus’s such as SARS, Norovirus etc. can work against this one.  

Cleaning first reduces the soil load on a surface and allows disinfectants to work properly.

CFS-US will use our typical cleaners such as EnviroSafe and EnviroTek which has the static-dissipative properties in the solution. CFS-US will also use CDC approved cleaners that hold a 75% alcohol content that kills bacteria, fungi and viruses.

Personal Protective Equipment (PPE) 

  • Cleaning staff will wear disposable gloves, appropriate Tyvek suits, a face mask, respirator or head sock that covers the mouth and nose, and safety glasses for all tasks in the cleaning process, including handling trash
    • Gloves, Tyvek suits and protective face wear should be compatible with the disinfectant products being used.
    • Additional PPE might be required based on the cleaning/disinfectant products being used and whether there is a risk of splash.
    • Gloves and Tyvek suits should be removed carefully to avoid contamination of the wearer and the surrounding area. Be sure to clean hands after removing gloves.
  • Gloves should be removed after cleaning a room or area occupied.  Clean hands immediately after gloves are removed.
  • Cleaning staff will immediately report breaches in PPE (e.g., tear in gloves) or any potential exposures to the Project Manager.


  1. Before starting service, seal off or limit access to areas where the confirmed or suspected case has visited to prevent unsuspecting persons from being exposed to those surfaces.
  2. Wipe down the following frequently touched surfaces in areas with disinfectant. 
  • Both sides and edges of all entrance doors from top to bottom.
  • Door handles and push plates inside and outside.
  • Badge readers at entrances.
  • Light switches.
  • Keyboard, monitor(s), mouse, telephone and accessible areas of horizontal desk top (please note this is a hygiene clean and not a full workstation clean for dust and residue removal).
  • Shared office equipment such as printers.
  • Tabletops and edges in meeting rooms.
  • Damp-mop / buff floors.
  1. Wipe down the following frequently touched surfaces in kitchens with disinfectant. 
  • Benchtops. 
  • Taps. 
  • Sinks. 
  • Cupboard doors. 
  • Drawer handles. 
  • Refrigerator door and handles.
  1. Wipe down the following frequently touched surfaces in data center area with disinfectant (if applicable). 
  • Exterior rack surfaces (not interior) including doors, door handles/knobs and side panels. 
  • Both sides of security cages, where present. 
  • All of the applicable surfaces in #2 for office areas. 
  1. Disinfect non-porous cleaning equipment used in one room before using for other rooms. 
  2. Disinfect buckets by wiping with disinfectant and rinse with hot water before filling.
  3. Discard all used PPE in a double-bagged biohazard bag, which should then be securely sealed with a cable tie and labelled as disinfection waste. 
  4. The crew should be aware of the symptoms and should report to their occupational health service if they develop symptoms.

After service is complete  

  • Place disposable equipment and supplies in bags (double-bagged) for transport and destruction. 
  • Place reusable equipment in black heavyweight bags (double-bagged) for transport and thorough disinfection offsite.  

CFS offers data center and COVID-19 cleaning throughout the United States and the United Kingdom.
