Nothing wrong praying whilst wearing PPE even if it covers the face and all of the body, so long as the worshipper is able to place his nose and forehead on the ground when prostrating. Also nothing wrong for a person doing Wuzu whilst wearing PPE, if he is able to wash the parts that must be washed and to wipe the head, even if that is by putting his wet hand under the PPE as long as there is a flow of water with few drops falling.
