British P Helmet / PH Helmet gas mask from c.1915

A PH helmet is a type of anti-gas helmet with glass eyepieces and breathing tube introduced at the end of the 1915. It was superseded by the box respirator. The P helmet and PH helmet was issued as an improvement on the Hypo helmet to meet the German use of phosegene-chlorine gas mixtures in 1915. The helmets were made of flannelette soaked at first in a solution containing sodium phenolate, and later with hexamethy-lenetramine added to the solution.[1]
