While traditionally it has always been used to spray disinfectants/pesticides in farms to control pests, insects, bacteria and viruses. It has emerged as a better way to surface sanitize during the COVID19 outbreak. Fogging using the right and approved sanitizers has proved to be effective in containment of the spread of the COVID19. From Wuhan, China to Nairobi, Kenya to USA and other countries world wide. COVID19 fogging has been done to disinfectant schools, malls, offices, stadiums, homes, clinics, hospitals, cars, trains, factories, and even streets.
Misting (also known as fogging) is the most effective and cost effective way to apply sanitizer to humans and their surrounding surfaces. Due to the super fine mist created by the misting system it will cover a human from top to bottom in less than 5 seconds. The amount of sanitizer applied can be controlled with the amount of nozzles used as well as by adjusting the duration intervals.
Environmental cleaning in healthcare facilities or homes housing patients with suspected or confirmed 2019-nCoV infection should use disinfectants that are active against enveloped viruses, such as 2019-nCoV and other corona-viruses. There are many disinfectants, including commonly used hospital disinfectants, that are active against enveloped viruses. Currently WHO recommendations include the use of:
- 70% Ethyl alcohol to disinfect reusable dedicated equipment (e.g., thermometers) between uses. Sodium hypochlorite at 0.5% (equivalent 5000ppm) for disinfection of frequently touched surfaces in homes or healthcare facilities.
- The coronavirus typically spreads from high-contact surfaces such as doors, chairs, and electronic devices or from direct human-to-human interactions.
Thermal scanners are effective in detecting people who have developed a fever (i.e. have a higher than normal body temperature) because of infection with the new coronavirus. However, they cannot detect people who are infected but are not yet sick with fever. This is because it takes between 2 and 10 days before people who are infected become sick and develop signs and symptoms.
Employers should start doing these things now, even if COVID-19 has not arrived in the communities where they operate. These measures can reduce working days lost due to illness and stop or slow the spread of COVID-19 if it arrives at one of your workplaces.
Make sure your workplaces are clean and hygienic
- Surfaces (e.g. desks and tables) and objects (e.g. telephones, keyboards) need to be wiped with disinfectant regularly
- Why? Because contamination on surfaces touched by employees and customers is one of the main ways that COVID-19 spreads. Fogging is recommended.
- Put sanitizing hand rub dispensers in prominent places around the workplace. Make sure these dispensers are regularly refilled
