David Waugh is putting down barrier tape and spraying yellow lines on the ground outside the main door of his school near Manchester.
Waugh, who oversees five schools in northwestern England, already has painted yellow arrows to ensure that children follow a one-way path around the building when they return next month from an extended break due to the coronavirus pandemic.
Soft furniture and play equipment have been cordoned off, and desks have been spread apart. Waugh has stocked up on 7,500 face masks, hundreds of pairs of gloves, hand sanitiser and other supplies.
