A LIFE-SAVING charity is stepping up measures to protect patients from the coronavirus. Essex and Herts Air Ambulance, which has a base in Earls Colne, is taking additional steps to protect patients and crew members from Covid-19 after adopting a decontamination technique. The trust is decontaminating crews and equipment with specially-prepared water which instantly kills 99.99 per cent of bacteria, fungi and viruses. The water is turned in to a ‘fog’ created from electrolysed saline water. The fog is then released inside a tent, into which anything that needs treating is placed. The environmentally-friendly system is said to be non-toxic, non-corrosive and leaves no harmful residues.
