Caring teachers from Oban High School鈥檚 Business, Design and Technology Department have now made more than 400 protective face visors for use in their local community. Damian Heaney, Ronnie Dott and David Berry created a prototype which was approved by the NHS, before setting about creating the visors using materials from the school鈥檚 technical department, such as acrylic, acetate and pop rivets.
