COVID-19 DISINFECTION SERVICE IN BANGALORE

The novel SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) also referred to as HCoV-19, is recognized as a global pandemic by the World Health Organization (WHO). The pathogen causes a disease known as COVID19.

• Virus spreads when someone carrying the virus speaks, coughs or sneezes.
• Small droplets of fluid carrying the virus land on people and surfaces around them
• Droplets that land on objects can be transferred to new patients via any contact – avoid touching your nose, eyes, mouth

The study below explores how COVID19 is deposited as aerosols on various surfaces.
A study in The New England Journal of Medicine from the National Institutes of Health, CDC, UCLA and Princeton University scientists compares the viability of SARS-Cov-2 
Hard surfaces could include many unique surfaces, not all of them non-porous.

• Non-Porous Surfaces : metals, glass, hard plastic
• Semi-Porous : wood, plaster, concrete, non-hard plastic
• Porous materials : includes carpets/padding, fabrics, ceiling tiles, insulation, wall boards (gypsum board or plasterboard), upholstered furniture and bedding.

Examples of Surfaces for Necessary Cleaning and Disinfection

Tables, Hard backed chairs, Door knobs, Light switches, Phones, Tablets, Touch screens, Remote controls, Keyboards, Door or fixture handles, Desks, Toilets, Sinks.

Sanitation and Disinfection

Sanitizer: 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. Used to reduce, but not necessarily eliminate, microorganisms from the inanimate environment to levels considered safe as determined by public health codes or regulations.

Disinfectant: a substance or mixture of substances, that destroys or irreversibly inactivates bacteria, fungi, and viruses, but not necessarily bacterial spores, in the inanimate environment. Used on, nonliving surfaces and objects to destroy or irreversibly inactivate infectious fungi and bacteria but not necessarily their spores. Disinfectant products are divided into two major types

Sterilant means a substance, or mixture of substances, that destroys or eliminates all forms of microbial life in the inanimate environment, including all forms of vegetative bacteria, bacterial spores, fungi, fungal spores, and viruses.

MERS-CoV (the beta coronavirus that causes Middle East Respiratory Syndrome, or MERS)
SARS-CoV (the beta coronavirus that causes severe acute respiratory syndrome, or SARS)
SARS-CoV-2 (the novel coronavirus that causes coronavirus disease 2019, or COVID-19)

Reapplying dirty water to a surface is never optional in a cleanroom, but is unavoidable with a single bucket mop system. Multi-bucket cleanroom mop systems provide a dedicated bucket for sanitation, clean rinse, and dirty rinse. One bucket provides a clean disinfectant, one a rinse disinfectant, and the last server as a waste bucket. Starting with the cleanest possible water is essential, opt for either distilled or ionized. Discard each mop pad or wiper after initial use and prevent cross-contamination or re-contamination . Mops or wipes should not be laundered and reused, otherwise there is a chance to re-contaminate the area. Following proper cleaning procedures are crucial to ensure best-case decontamination.

Biological decontamination by hand is time-consuming and subject to human error. Dry fogging penetrates normally inaccessible areas for top to bottom decontamination. Dry foggers produce droplets as small as 7.5 microns which reduce condensation, surface wetting, and possible corrosion. Area coverage is more uniform and the fog penetrates cracks, crevices, ventilation systems and other challenging areas like high corners and underneath furniture.
