These are the PPE pioneers from Protecting Heroes who have teamed up with the scientists from the National Physical Laboratory (NPL) Teddington to build and distribute a new safety visor, which has been described as the 'safest in the world.

The first batch of masks was sent from the NPL's Sports Pavilion which is being used as a makeshift assembly line and depot, to University College Hospital in London today.
