Today on LBC radio, Adrian Gee-Turner explained the ways in which taxis can be decontaminated by fogging with Nemesis eH2O. The fogging of disinfectant removes contamination from surfaces and the air within confined spaces, and is particularly advantageous where some of the surfaces are difficult to access. In the following blog, Adrian explains the advantages of using Nemesis eH2O (hypochlorous acid, HOCl) as a fogging agent:
Most of the commonly employed fogging disinfectants are utilised after normal cleaning operations, and provide effective decontamination of pathogenic micro-organisms. However, they can also represent a potential hazard to operators and necessitate COSHH compliance and the use of personal protective equipment (PPE).
Hydrogen peroxide vapour for example, demonstrates efficacy against viruses, bacteria, yeasts, and bacterial spores, but it can be harmful to humans, so great care has to be taken during disinfection operations. Typically, areas to be disinfected with hydrogen peroxide have to be cleaned, evacuated and sealed before fogging can commence. Following treatment, any remaining hydrogen peroxide vapour should be removed before re-entry is permitted. In the UK, the Workplace Exposure Limit (WEL) for airborne hydrogen peroxide is just 1ppm as an 8-hour time weighted average and just 2ppm as 15-minute time weighted average.
As a fogging disinfectant, Nemesis eH2O offers all of the advantages of hydrogen peroxide, but without the disadvantages. Both products offer 99.9999% kill (6-log) of harmful micro-organisms, but crucially, Nemesis eH2O is not harmful to humans, and can even be sprayed directly on sensitive skin as an antiseptic. The only by-product of disinfection with Nemesis eH2O is slightly salty water, so there is no harmful waste and no threat to the environment.
Summarising, Adrian says: “Fogging with Nemesis eH2O is a quick and easy method of decontamination. Fogged Nemesis eH2O should be allowed to settle onto all surfaces for 30 seconds to 1 minute before wiping off smooth surfaces such as table tops, sideboards and glass surfaces.
“Areas of high frequency contact such as door finger plates, door handles, light switches, chair arms etc. will require more frequent treatment with the handheld spray versions (750ml) of Nemesis eH2O.”
