Gasmask Testers

This was obviously before the creation of OSHA, or its British equivalent.

Let me try and understand this method. The masks are hook up to a source of a toxic gas. The toxic gas does not pass through the filters? If not, then of course the men are going to be adversely affected by the toxic gas. On the other hand if the supply hose is hooked up to the intake side of the filters then this might (emphasis on might) be a way to test the masks. It does cause me to wonder if enough oxygen is mixed in with the toxic gas on its way through the filter.

I am interested in this as I was trained as a "chemical, radio, biological" NCO during my stint with the army in the late 60's. We trained with the mask using CS tear gas. It did not take long to find out if your mask was not working properly. Also some training was done with very weak concentrations of chlorine gas.

I remember modifying an old surplus gas mask as a smoking device. You can imagine what was used in the bowl.
