The MUA is a Polish industrial gas mask (MUA is a name given to a kit for industrial purposes and military version is designated SzM-41M KF even though its a face piece name it's also a kit name). which probably started use in 1960's and was used till 80's. It was very similar to the ShM-41.
Like it's Russian counterpart, the MUA was made of rubber with circular eye pieces. The MUA was equipped with a round, black voice emmiter that differed from the Russian emitters because of it's size and shape. The face piece name is SzM-41 KF.
Comes with two paint variants: Light green and Camo wz. 58 "Deszczyk". Meant to be carried on shoulder but due lack of chest belt availability and high interia, soldiers use to carry it on back. Inside it's divided to three bays for mask's equipment and one outside for field patch.
- The MUA is often called "Słoń" due to the rubber pipe that looks like an elephant's trunk.
