Coronavirus - limiting the spread.

Coronaviruses are a large family of viruses. Some can cause illness in people including mild symptoms, such as the common cold. Other strains can lead to pneumonia and cause more severe disease e.g. SARS and MERS. 

Surface disinfection

V1 Firewall Virucidal cleaner (B4250 5lt and B3920 750ml) have been assessed for virucidal activity following test methods such as BS EN 14476 and BS EN 14675. Results show they are effective against a range of viruses such as the H1N1 influenza virus, Hepatitis B, Hepatitis C, HIV and the Ebola virus. The Coronavirus is not currently available for commercial laboratories to test against so we cannot give a definitive contact time and dilution rate. However, given the above test data we can reasonably expect V1 Firewall Virucidal cleaner to have efficacy against the virus. We would therefore recommend using the below products for general disinfection in the infection prevention and control for the 2019-nCoV.

  B4250 5 litre V1 Firewall Virucidal cleaner   1 : 10   5 minutes



Where specific cases are suspected or identified we would recommend an additional step of applying 1000ppm bleach (after precleaning with V1 Firewall). We advise the use of V1 Firewall for precleaning to minimise the risk that the cleaning cloths become a source of cross contamination. 


To achieve 1000ppm bleach see below products.
