ABSTRACT OF THE DISCLOSURE The protective covering has a helmet part and a body part at least partly covering the body. An oxygen cartridge is screwed in a connection member on the chest portion of the body part and a cartridge opener is displaceably mounted therein to open the sealed oxygen cartridge when an actuating cord attached to an actuating lever is pulled. The oxygen is reduced to a lower pressure in a metering throttle and conducted to the helmet part with constant circulation. Using the oxygen cartridge as the oxygen source provides a simple and cost-effective solution to enable the protective covering to be used even in a harmful gas atmosphere as effective protection for the wearer.
