Spectrum will carry out a 3 stage Deep Cleaning Process to support in minimising the risk of Coronavirus Covid-19 infection.
Stage one: Planning & Preparation
As with any project Spectrum takes on planning and preparation is vital. All team members will be in full PPE (Personal Protection Equipment). While performing the Deep Cleaning Process, we make sure that all of our employees are protected so that they may not be infected by the microorganisms. This is also done to prevent the possibility of spreading the microorganisms outside your facility. Our teams will set up any required barrier or rope systems necessary to carry out the comprehensive Disinfecting and Deep Cleaning service.
Stage Two: Application
We will carry out Touch-point Surface Cleaning. We will ensure that we focus on cleaning and sanitising all regular-touch points on and around your building.
The frequently touched surfaces surrounding your premises are likely to include the following:
• Doorknobs, doorplates & handles
• Light switches
• Outdoor Chairs / Benches
• Lifts and escalators
• Any additional public areas.
All Deep Cleaning and Disinfecting services use anti-microbial disinfectants.
Stage Three: Steam
Due to the fact that COVID-19 has a lipid host cell membrane(2) which means it is sensitive to extreme temperatures. High-temperature steam and boiling water is also a very effective way of reducing the risk of contact transmission.
Our specialist, Steam Cleaning System, will ensure that once all areas have been disinfected, they are coated with a layer of high-temperature low-pressure steam. The 55C temperature will kill off any remaining bacteria, and the use of low-pressure steam will prevent large volumes of water running off the surfaces of your building.
Coronavirus - what you need to know
To keep you updated with the latest facts, we have summarised some key points for our industry from World Health Organisation Publications.
There are two main routes of transmission of the COVID-19 virus: respiratory and contact. Respiratory droplets are generated when an infected person coughs or sneezes. Any person who is in close contact with someone who has respiratory symptoms (for example, sneezing, coughing) is at risk of being exposed to potentially infective respiratory droplets (3). Droplets may also land on surfaces where the virus could remain viable; thus, the immediate environment of an infected individual can serve as a source of transmission (known as contact transmission).(4).
The provision of safe water, sanitation and hygienic conditions is essential to protecting human health during all infectious disease outbreaks, including the COVID-19 outbreak. Ensuring good and consistently applied WASH and waste management practices in communities, homes, schools, marketplaces and health care facilities will further help to prevent human-to-human transmission of the COVID-19 virus. The World Health Organisation has shared below as the most important information (3).
Frequent and proper hand hygiene is one of the most critical measures that can be used to prevent infection with the COVID-19 virus. WASH practitioners should work to enable more frequent and regular hand hygiene by improving facilities and using proven behaviour change techniques.
WHO guidance on the safe management of drinking-water and sanitation services applies to the COVID-19 outbreak. Extra measures are not needed. In particular, disinfection will facilitate more rapid die-off of the COVID-19 virus.
Many co-benefits will be realised by safely managing water and sanitation services and applying good hygiene practices. Such efforts will prevent many other infectious diseases, which cause millions of deaths each year.
Can Covid-19 spread through drinking-water or sewage?
Currently, there is no evidence about the survival of the COVID-19 Virus in drinking-water or sewage.
The morphology and chemical structure of the COVID-19 virus are similar to those of other surrogate human coronaviruses for which there are data about both survival in the environment and effective inactivation measures.
While persistence in drinking-water is possible, there is no current evidence from surrogate human coronaviruses that they are present in surface or groundwater sources or transmitted through contaminated drinking-water.
The COVID-19 virus is an enveloped virus, with a fragile outer membrane. Generally, enveloped viruses are less stable in the environment and are more susceptible to oxidants, such as chlorine. While there is no evidence to date about the survival of the COVID-19 virus in water or sewage, the virus is likely to become inactivated significantly faster than non-enveloped human enteric viruses with known waterborne transmission.
The COVID-19 virus has so far not been detected in drinking-water supplies and based on current evidence, the risk to water supplies is low (5). however, as the virus is still so new, it is important that we take appropriate methods to slow down and prevent any chance of the virus spreading.
How do you effectively clean to prevent the spread of Covid-19?
Other human coronaviruses have been shown to be sensitive to chlorination and disinfection with ultraviolet (UV) light (6). As enveloped viruses are surrounded by a lipid host cell membrane, which is not robust, the COVID-19 virus is likely to be more sensitive to chlorine and other oxidant disinfection processes than many other viruses, such as coxsackieviruses, which have a protein coat.
For effective centralised disinfection, there should be a residual concentration of free chlorine of ≥0.5 mg/L after at least 30 minutes of contact time at pH < 8.0 (4). A chlorine residual should be maintained throughout the distribution system. Heat, high or low pH, sunlight and common disinfectants (such as chlorine) all facilitate die off.
Can Covid-19 survive on surfaces?
Yes, however, it is not certain how long the virus that causes COVID-19 survives on surfaces, but it seems likely to behave like other coronaviruses. A recent review of the survival of human coronaviruses on surfaces found large variability, ranging from 2 hours to 9 days (7).
The survival time can depend on a number of factors (3);
· Type of Surface.
· Relative humidity.
· Specific Strain of Virus.
The same review also found that effective inactivation could be achieved within 1 minute using common disinfectants, such as 70% ethanol or sodium hypochlorite.
What can businesses do to help prevent the spread of Covid-19?
We are providing disinfecting and cleaning services to help prevent the spread of this virus. We wanted to ensure that our clients and customers felt informed with enough fact to be able to make decisions to support the prevention of this virus rather than sharing fear-based headlines.
1. Frequent and proper hand hygiene is one of the most critical measures that can be used to prevent infection with the COVID-19 virus
2. COVID-19 is an enveloped virus and therefore is surrounded by a lipid host cell membrane, which is not robust. This means that exposure to chlorine and oxidant disinfection processes will be effective. Washing down public areas with the correct chemicals will help to prevent the spreading of COVID-19.
3. The lipid host cell membrane of COVID-19 is also sensitive to extreme temperatures. High-temperature steam and boiling water is also a very effective way of reducing the risk of contact transmission.

5. If you suspect that your business premises, your customers or any of your staff may be at risk of infection from the Coronavirus you need to act. Spectrum have the expertise and appropriate equipment to carry out coronavirus infection control on your premises. We will execute the disinfection of your business premises to the appropriate standard which will allow you to keep on trading.
Government Guidelines | COVID-19: cleaning in non-healthcare settings:
Public areas where a symptomatic individual has passed through and spent minimal time, such as corridors, but which are not visibly contaminated with body fluids can be cleaned thoroughly as normal.
All surfaces that the symptomatic person may have come into contact with must be cleaned and disinfected, including:
• objects which are visibly contaminated with body fluids
• all potentially contaminated high-contact areas such as bathrooms, door handles, telephones, grab-rails in corridors and stairwells
Avoid creating splashes and spray when cleaning.
Any cloths and mop heads used must be disposed of and should be put into waste bags as outlined below.
When items cannot be cleaned using detergents or laundered, for example, upholstered furniture and mattresses, steam cleaning should be used.
Any items that are heavily contaminated with body fluids and cannot be cleaned by washing should be disposed of.
If possible, keep an area closed off and secure for 72 hours. After this time the amount of virus contamination will have decreased substantially and you can clean as normal with your usual products. (1)
Waste from possible cases and cleaning of areas where possible cases have been (including disposable cloths and tissues):
1. Should be put in a plastic rubbish bag and tied when full.
2. The plastic bag should then be placed in a second bin bag and tied.
3. It should be put in a suitable and secure place and marked for storage until the individual's test results are known.
Waste should be stored safely and kept away from children. You should not put your waste in communal waste areas until negative test results are known or the waste has been stored for at least 72 hours.
• if the individual tests negative, this can be put in with the normal waste
• if the individual tests positive, then store it for at least 72 hours and put in with the normal waste
If storage for at least 72 hours is not appropriate, arrange for collection as a Category B infectious waste either by your local waste collection authority if they currently collect your waste or otherwise by a specialist clinical waste contractor. They will supply you with orange clinical waste bags for you to place your bags into so the waste can be sent for appropriate treatment.(1)
