Traditional gas masque are designed to seal to your face and neck opening , protecting you from breathing harmful chemical or biological agents . But they wo n’t crop with full beards , which is a trouble if you ’re a Sikh warrior like Harjit Sajjan . His solution ?
Sikhs are rarified in westerly militaries . The US , for deterrent example , has 1.4 - million dynamic duty staff office , only three of which are Sikh . And , religious exemptions and current special violence practise aside , the military in general prohibits both shaggy-haired facial hair and religious headwear . So , most gas masks are designed for clean - shaven font and either unornamented head or single fitted with standard helmet .
This is all obviously a job if , likeHarjit Sajjan , you recover yourself overtop a Canadian Army regiment in Afghanistan . So , he designed and patented his own gas pedal mask .
Thepatent abstractreads :
A protective cowling is allow for wearers of gas masks in emergency situations . The hood is formed to bring home the bacon a “ man-made hide ” for the wearer ’s head , with chess opening for the eyes , nose and mouth , and neck . A smooth surface around such curtain raising provides for a sealing contact with the flatulence mask which is donned over the hood . Various agency are provided for constringe the strong-armer about the neck to ensure a gas pedal - besotted tangency . Circulation means within the lens hood , and a pouched ice gel pack on the exterior of the hood , is provided to cool down the wearer ’s head .
The approximation is to enclose the byssus within the protective toughie , making the seal around the lower neck and with the protective eyewear or else of against the case and upper neck .
Traditional gas masks like this US Army M50 seal off around the brass ’s perimeter , get hold of silicone polymer to hide . That seal would not be workable with a whiskers and turban .
But what of the toque ?
The lens hood of any one of claims 1 , to 7 , wherein said head portion is profiled in a turban - like shape .
The patent was originally filed in 1996 and issued in October , 2006 . It ’s not clear-cut if Sajjan ever produced or used the masquerade .
