The use of a barrier about 2–2.5 m high made of a canopy fabric (cover mat) of no less than 300 g/m2 guarantees efficient safety against robust wind gusts and, consequently, towards the spread of malodorous gases and bioaerosols. Figure thirteen shows an example of a protect material barrier at a wastewater treatment plant in Zakopane (Poland).
