The S.I.P. 1 is the 1th gas mask approved by the S.C.M. (Servizio Chimico Militare, chemical military service) on 26 may 1934.
Mask overview Edit
The S.I.P. 1 is an helmet style mask made with cheap and thin rubber. Its eye pieces are made of acetylcellulose, in the front it has the exhale valve and under it the filter thread.
The filter was a small cylinder filled with blocking substances. This kind of filter was better than the P.C. 30 filter but worse than the later civilian filters, which would replace this kind of filter in the S.I.P. 1 kit.
The mask came in a metal tube with its filter, a small box with a spare exhale valve, a stick of anti-fogging soap and an instructional pamphlet.
S.I.P. 2 EditThis variant used a panoramic visor and straps. Because of the first quality mentioned, this mask was used mainly by children.
S.I.P. 3 Edit
The S.I.P. 3 is the 6th gas mask approved by the S.C.M. (Servizio Chimico Militare, chemical military service) on 31 august 1934. This variant sported a panoramic visor like the S.I.P. 2, but it used the helmet style much like the S.I.P. 1.
