Coronavirus – Cleaning and Sanitising

Combating Coronavirus (COVID-19): Cleaning and Decontaminating

 

The following are some simple steps that could be followed to decontaminate and clean in non-healthcare facilities (e.g. rooms, public offices, transport, schools, etc.) where confirmed COVID-19 cases have been (but are no longer present) before being admitted to hospital.

In the absence of an outbreak, although there is lack of specific evidence for their effectiveness against SARS-CoV-2, cleaning with water and household detergents and the use of common disinfectant products should be sufficient for general precautionary cleaning [1]

All recommendations in this publication are provided as is and are not proven effective in combating SARS-CoV-2. Always seek qualified professional advice.

 

1: Ensure the appropriate personal protective wear is worn*

The guidance over the use of face masks is constantly changing! Recommendations vary from using FFP2 or FFP3 filtering face pieces respirators [1], to using surgical-style masks simply to prevent the use from touching mouth/nose with gloves/hands [2]. Always check current professional guidance and use appropriate measures. See the additional links below for more information

Goggles or a face shield

Disposable long-sleeved water-resistant gown or coverall

Disposable gloves

Disposable overshoes if body fluids (sputum, etc.) present

Disposable PPE

 

2: Clean all surfaces with a neutral detergent

Follow manufacturers recommended guidelines for cleaning and use of PPE if additional PPE required. Use disposable cloths and ensure all waste is treated as potentially contaminated. Seek professional advice on the correct treatment and disposal of contaminated equipment and waste.

3: Decontaminate with 0.1% sodium hypochlorite solution

UPDATE 11.3.2020: A report published by UNICEF, WHO and IFRC on the 10th March now recommends using a 0.5% sodium hypochlorite solution.

After cleaning, sanitise all surfaces methodically with a bleach solution (approximately 1:50 dilution to achieve 0.1% sodium hypochlorite content). For surfaces that could be damaged by sodium hypochlorite, use an alcohol-based hard surface cleaner (or similar) with a 70% ethanol concentration. [1]

 

 

4: Safely dispose of all waste and remove PPE

All protective wear and cleaning equipment used should be regarded as contaminated/hazardous waste. Seek professional advice on the correct treatment and disposal of contaminated equipment and waste. Ensure all operatives are familiar with and follow the correct procedure for safe removal of contaminated PPE.
