WHAT WE KNOW

TODAY ABOUT

COVID-19

(3)

COVID-19 is a Lipid Virus or “Envelope Virus”

Lipid Virus

• Surrounded by envelope of lipoprotien

• Envelope is relatively sensetive

• Generally, easily inactivated by many types of disinfectants

‒ Alcohols, such as ethanol or 2- propanol.

‒ Can be killed by disinfectants that are virucidal against enveloped viruses.

How long does it live?

• Aerosol form up to 3 hours

• Cardboard up to 24 hours

• Plastic up to 72 hours

• Stainless steel up to 48 hours

• Copper up to 4 hours

How long does it live?

(5)

What inactivates COVID-19?

• Products with EPA-approved emerging viral pathogens claims are expected to be effective

against SARS-CoV-2 based on data for harder to kill viruses.

• Enveloped viruses are easier to inactivate

• As of today, NO product has a direct claim.

• Test methods have yet to be developed.

What inactivates COVID-19?

(6)

How is COVID-19 Transmitted?

• Close contact, within 6 feet, via respiratory drops

• Transmission from surfaces (fomites) has not been

documented

• Scientists say there is a lot to

learn, but suspect transmission is similar to SARS-CoV from 13

years ago

How is COVID-19 transmitted?

(7)

Hygiene helps!

• Wash hands for 20 seconds

• Use a 60% alcohol-based hand sanitizer

• Avoid touching your eyes, nose, and mouth after touching

surfaces

TERMINOLOGY

Cleaning, Sanitizing, Disinfecting, and Sterilizing

(9)

Cleaning

• Removes germs, dirt, and impurities from surfaces or objects.

• Cleaning works by using soap (or detergent) and water to physically remove germs from surfaces.

• This process does not

necessarily kill germs, but by removing them, it lowers their numbers and the risk of

spreading infection.

TERMINOLOGY TERMINOLOGY

Cleaning

(10)

Sanitize

• Reduction of bacterial

contaminants to safe levels as judged by public health

requirements.

• A substance, or mixture of substances, that reduces the bacteria population in the inanimate environment by

significant numbers, but does not destroy or eliminate all bacteria.

Sanitize

(11)

Disinfect

• Thermal or chemical destruction of pathogenic and other types of microorganisms.

• Disinfection is less lethal than sterilization because it destroys most recognized pathogenic microorganisms but not

necessarily all microbial forms

Disinfect

(12)

Disinfect

• A substance or mixture of substances, that destroys or irreversibly inactivates bacteria, fungi, and viruses, but not

necessarily bacterial spores, in the inanimate environment.

(Code of Federal Regulations, 2018)

Disinfect

(13)

Sanitize versus Disinfect

• For commercial products, this simply means that disinfectants provide a higher level of

demonstrable microbial load reduction than sanitizers.

• Product performance guidelines are outlined by EPA in Product Performance Test Guidelines OCSPP 810.2300 (sanitization) and OCSPP 810.2200

(disinfection).

(14)

(15)

Sterilize

• Validated process used to render a product free of all forms of

viable microorganisms.

• In a sterilization process, the presence of microorganisms on any individual item can be

expressed in terms of probability.

• Although this probability can be reduced to a very low number, it can never be reduced to zero.

Sterilize

(16)

Contact Time

• Time a disinfectant is in direct

contact with the surface or item to be disinfected.

• For surface disinfection, this period is framed by the

application to the surface until complete drying has occurred.

Contact Time

Best practices when it comes to cleaning and disinfection

(18)

Best Practices

• Best practice measure for prevention of COVID-19 and

other viral respiratory illnesses in community settings.

• If surfaces are dirty, they should be cleaned using a detergent or soap and water prior to

disinfection.

CLEAN BEFORE DISINFECTION CLEAN BEFORE DISINFECTION

Best Practices

(19)

Best Practices

• Routinely clean all frequently touched surfaces in the

workplace, such as workstations, countertops, and doorknobs.

• Use the cleaning agents that are usually used in these areas and follow the directions on the label.

Best Practices

(20)

Vital Oxide and One-Step Cleaning and Disinfection

• As always it is recommended to clean first clean then sanitize or disinfect.

• Some disinfectants, such as Vital Oxide, have a one step-cleaning and disinfection claim.

• Products such as these can have a combined cleaning and

disinfection step.

(21)

• It is still recommended to first remove any gross visible soil on fomites.

GENERAL CLEANING PRACTICES

WHAT WE KNOW TODAY ABOUT COVID-19

04 GENERAL CLEANING PRACTICES

(23)

Cleaning High Touch Areas

• This means daily sanitizing surfaces and objects that are touched often

‒ desks

‒ countertops

‒ doorknobs

‒ computer keyboards

‒ faucet handles,

‒ phones

‒ toys

GENERAL CLEANING PRACTICES GENERAL CLEANING PRACTICES

Cleaning High Touch Areas

(24)

Pressure Washing

• Pressure wash outside surfaces with hot water and high pressure before disinfection

‒ Mailboxes

‒ Playground equipment

‒ Benches

‒ Tables

Pressure Washing

(25)

Carpet

• For soft (porous) surfaces such as carpeted floor, rugs, and drapes, remove visible contamination if present and clean with

appropriate cleaners indicated for use on these surfaces

• Use products with the EPA- approved emerging viral

pathogens claims that are suitable for porous surfaces.

Carpet

(26)

When working with equipment

• Wear gloves

• Wash hands after touching equipment

• Spray disinfectants on brushes, squeegees, and in recovery tanks

(28)

HEPA Vacuums

• Use HEPA filters for containment of any air exiting the system.

• COVID virus is 125nm or

equivalent to 0.125 microns.

• Our HEPA products clean the air to 0.03 Microns at 99.97% (HEPA Guidelines)

• Our vacuums actually help to

reduce the virus in the air through the filtration process.

AP 100/50

• Thoroughly clean then disinfect with dual chemical metering.

• No touch cleaning protects workers from potential

transmission through touching surfaces during cleaning.

• Make sure that the restrooms support the use of the Compass and do not have drywall near

toilets, sinks, mirrors, and urinals.

AP 100/50

(30)

Vital Oxide

• For Vital Oxide recommended use is a 10 minute contact time at the undiluted disinfectant level

concentration. Vital Solutions, in currently in process for the EPA emerging viral pathogens for the product Vital Oxide 82972-1.

• The CDX number is

CDX_2020_001747 and the EP number is 745699

Vital Oxide

(31)

Vital Oxide

• Registered as a carpet Sanitizer, so it could be used to sanitize all soft surfaces such as carpet or leather.

• Needs 60 minutes of contact time.

• Test first to avoid any damage to the surface, such as color change on leather.

Vital Oxide

(32)

Vital Oxide

Vital Oxide Summary:

• Viral disinfection: 10 minute contact time

• Soft surface sanitization: 5 minute contact time

• Carpet sanitization: 60 minute contact time

• Note: there are no EPA tests for soft surface or carpet disinfection at this time.
