Many concerned leaks and spillages of virus-laden fluids, however investigations additionally happened right into a flood at an animal facility housing Covid-infected monkeys, combine ups that led scientists to work on dwell virus by mistake and a researcher being bitten by an contaminated ferret.

On a number of events, scientists labored on dwell virus with out correct security measures as a result of they believed the virus had been killed, whereas in different incidents, Covid constructive take a look at samples have been transported with out right precautions. In accordance with HSE experiences, two healthcare employees at a hospital in Chichester turned contaminated with Covid after not carrying PPE, however there isn’t any proof lab employees caught the virus in work-related blunders.

The Nationwide Institute of Organic Requirements and Management, operated by the UK medicines regulator, was investigated after a flood at an animal facility housing Covid-infected marmosets. The identical lab was later discovered to have breached a number of security rules when researchers noticed water droplets on the lab bench and ground after heating Covid virus inventory.

Public Well being England’s Porton Down laboratory, which additionally carried out essential work within the Covid pandemic, was ordered to enhance security after a researcher was bitten by an contaminated ferret. An investigation into the incident in Might 2020 discovered the animal sliced by means of the scientist’s protecting clothes and drew blood, main managers to ship the researcher house to take care of the wound and self-isolate.

The HSE served a “Crown enchancment discover” on the Wiltshire lab and requested managers to beef up security throughout a number of services. However with employees “over-stretched” because of “a doubling of workload”, the case was not closed for a yr.
