Disinfecting Large Scale Areas

Disinfecting Large Scale Areas

Posted on April 14, 2020

What to do when a suspected or confirmed positive test indicates that you need to disinfect a large area of your facility?  Manufacturers across the country are working hard to find disinfectants and cleaners suitable to disinfect their facilities against viruses, and more and more frequently finding it difficult to get what they need.

A technology and process gaining traction and attention currently is Ultra Low Volume fogging.  Ultra low volume (ULV) fogging machines are cold fogging machines that use large volumes of air at low pressures to transform liquid into droplets that are dispersed into the atmosphere.  When using an appropriate product, this process can be very effective at killing bacteria, funguses, and some viruses – including those in the coronavirus family.

When selecting a company to perform ULV fogging for you, ensure that the chemical that they are using is listed on the hard surface disinfectants list from Health Canada:  https://www.canada.ca/en/health-canada/services/drugs-health-products/disinfectants/covid-19/list.html#tbl1.  Keep in mind, these products are tested using a specific delivery method, and the company offering services needs to be using the product according to the manufacturer’s directions and the product information connected to the Drug Identification Number issued by Health Canada. Off-label use has not been proven to be effective and may not be effective. A glass of chocolate milk taken orally can be nutritious and delicious. A glass of chocolate milk makes a big mess. Delivery method counts. Every product on this list also has a contact time that is required to kill the intended virus. The application method must be able to satisfy the contact time.

A COVID-19 by nature is a novel virus, new to humans, there has been extremely limited time for testing. Products on the above list will have been found effective against other viruses of similar construction.  Products new to the market of similar chemistry may be effective, but have not been proven to be such.  Your cleaning service should be aware of this and assist you in making the right choice for your facility.
