How to disinfect public surfaces

At present, the novel coronavirus pneumonia epidemic is still rampaging around the world. Disinfection measures are very important to reduce the possibility of contamination by the covid-19 virus in non-medical places such as homes, offices, schools, gyms, public buildings, religious community centers, markets, transportation and commercial places or restaurants. Priority should be given to disinfection of high contact surfaces in these non-healthcare settings, such as door and window handles, kitchen and food preparation areas, countertops, bathroom, toilets and faucets, touch screen personal devices, personal computer keyboards and work surfaces. The following information provides guidelines for cleaning and disinfecting public spaces and workplaces:
1. Wiping and sweeping with the disinfectant. This method is to wipe and sweep the disinfectant in public places through rags, mops, etc. This method is also the most common way used in public places at present, with the advantages of simple and convenient implementation and low equipment cost. Of course, the disadvantages are also obvious: it can only disinfect the objects and the ground surface, but not the air in the area; Direct contact with disinfectant will damage human skin; The consumption of human resources is large; The effective utilization rate of disinfectant is low.

2. UV Lamp disinfection. The advantages of this method are that it only needs to be set to turn on regularly without manual intervention and saves human resources. But the practicability is poor, and the organisms, minerals and suspended solids in the water will deposit on the surface of the UV lampshade, affecting the sterilization effect.

3. Portable electrostatic sprayer disinfection. Usually, the electrostatic sprayers are divided into handheld sprayers and backpack sprayers. Portable electrostatic sprayer is also the most effective disinfection method with the best disinfection effect. It has the advantages of saving manpower, covering all the surfaces, saving disinfectant resources, easy to carry and work.

But at present, there are a lot of these types of equipment in the market, and the level of equipment manufacturing is uneven. Either it is the more primitive pressing pressure operation mode, which is inconvenient to use; Or spray density is not up to standard, as a result, the disinfection effect is not good. If you decided to use portable electrostatic sprayers for disinfection, make sure you buy the device from a trusted brand.

Our portable electrostatic sprayer is not only of excellent quality but also has different types of products for different killing scenes. At present, there are two corresponding products for disinfection work in public places: handheld disinfectant electrostatic sprayer ML-X001 and backpack electrostatic sprayer ML-X002. The handheld electrostatic sprayer is more suitable for killing in small areas and small spaces, while the backpack electrostatic sprayer is more suitable for killing in large areas such as halls and roads; After the electrostatic spray function is applied, a better disinfection effect can be achieved by strong adsorption of positive ions. The droplets produced by the electrostatic sprayer can be evenly distributed in the air and float for a long time, to effectively disinfect the air and dust. Our product is powered by a high-performance lithium battery pack, which is safe and easy to carry. What’s more, it uses a high-quality high-pressure silent water pump for better use.

To sum up, Cleaning public spaces can be a challenge, especially if those spaces include various surfaces that are difficult to clean and disinfect. In that case, the most practical and effective disinfectant method in public places would be the portable electrostatic sprayer.

What pathogens are in healthcare environments, where are they and does it matter?

Right now many of us are slathering our counter tops with Lysol and bleach to prevent the spread of COVID-19 but is it doin’ the job? When we refer to ‘bleach’ and ‘Lysol’ we tend think of them as equal: one tube of Lysol wipes is the same as the others and only the fragrance is different…wrong! There are key pieces of info to review using when disinfecting surfaces.

1 – Don’t forget to clean it first!

Before disinfecting it is crucial to thoroughly clean the surface with soap and water. Why? Debris, dirt, grime, whatever you want to call it. All disinfecting products have a minimum amount of time they must remain on a surface to work properly, called contact time, and if they’re just sitting on top of those pesky toaster crumbs or a thin film of coffee they aren’t doing anything for the underlying surface.

2- What should we be disinfecting?

Another key is what to disinfect. We want to prioritize high-touch surfaces which are exactly what they sound like: surfaces that are handled frequently. Some common examples include:

  • General
    • Tables/Counter tops
    • Light switches
    • Handles of any kind
  • Offices
    • Desks, phones and keyboards
  • Bathrooms
    • Toilets, sink handles and faucets

There are many others and they’re dependent on lifestyle. Have an active family with lots of exercise equipment? Clean and disinfect. Lots of video games? Headsets, controllers and other handheld components need disinfecting. Whatever your family touches or handles several times a day, disinfect it.

3 – Disinfectants are not created equal

Each EPA approved disinfectant has been through a battery of tests to determine how it must be used to actually disinfect surfaces which is why it’s critical to read the manufacturer’s instructions on the label before use. There are three crucial things to review on the label.

First off you want to look for the contact time which is the amount of time the surface must remain visibly wet with the product for it to work correctly. EPA approved products have contact times between 15-seconds and 10-minutes which is a big range when considering how we clean our houses. How often do you wipe off a table with Lysol and leave it for a full 10-minutes before drying it? Contact times vary between product and even within the same brand so it’s crucial to double check every time you use a new one! For example, Lysol® Brand Deodorizing Disinfectant Cleaner has a contact time of 10-minutes but Lysol® Brand All Purpose Cleaner has a contact of 2-minutes yet they look very similar. See below:

This document provides guidance on cleaning and disinfecting of public settings, including schools, universities, public libraries, museums, public transit, communal residences and workplaces.

What you should know

  • Surfaces frequently touched with hands are most likely to be contaminated. These include doorknobs, handrails, elevator buttons, light switches, cabinet handles, faucet handles, tables, countertops and electronics.
  • We don’t know exactly how long the virus causing COVID-19 lives on different surfaces. However, evidence suggests it can live on objects and surfaces from a few hours to days, depending on the type of surface.

Choose a product that cleans and disinfects

  • When cleaning and disinfecting public spaces, choose products that clean and disinfect all at once (e.g., premixed store-bought disinfectant cleaning solutions and/or wipes when available).
    • Cleaning with soap (or detergent) and water lowers the number of germs on surfaces. Cleaners don’t necessarily kill germs, but cleaning can remove germs and lower their numbers. This can play a role in reducing the risk of spreading infection.
    • Disinfecting products kill germs on surfaces using chemicals.
  • Use only approved hard-surface disinfectants that have a Drug Identification Number (DIN). A DIN is an 8-digit number given by Health Canada that confirms the disinfectant product is approved and safe for use in Canada. If an approved disinfectant isn’t available due to supply issues, use a diluted bleach solution.

Create a cleaning and disinfecting procedure

Business owners and operators of community settings should develop or review protocols and procedures for cleaning and disinfecting public spaces. They should:

  • be aware of occupational health and safety requirements
  • know and meet the requirements under the Workplace Hazardous Materials Information System (WHMIS) about hazardous products in the workplace
  • have or establish processes for cleaning and disinfecting the site, including precautions for if an employee or visitor develops COVID-19 symptoms

This will help determine where improvements or additional cleaning and disinfecting may be needed.

The following directions will help prevent the spread of infection.
