For Nitrogen gas can I use Oxygen Mask (Non Rebreather)- Image of mask attached.

[randomsomeonein]

I have a nitrogen gas cylender and a flowmeter attached to it.
I will connect the flow meter to my oxygen mask (non rebreather)




PPE says with exit bag (poly bag on head) you need 15 ltrs per min flow of nitrogen.
If I can use this, then what should I adjust my flowmeter to?


Please help.

Some people here in the past advised against using those types of masks due to the difficulty in getting a perfect seal around the mask edges. I think some people tried them, but found that it was difficult to prevent oxygen getting in the side of the mask.

Not advisable to use this

 

[Glandular]

No because the seal is not perfect. SCUBA/SCBA or bag a better

can you show what scuba mask?

I would think the below kind of respirator mask should work. They are one way and allow controlled air to come in & then can exhale thru a one way valve.
This particular mask is used for painting situations with an air compressor or in my case a Nitrogen tank.
Its just getting the hoses to connect to the regulator, but that can be figured out a variety of ways.
(Of course the air/oil filter isnt used)

How do you deal with the overpressure? Connecting it directly to the mask from the regulator may cause it to build overpressure unless the mask has a built in relief valve? When you stop breathing the gas is still coming in the mask and it has to go somewhere. I guess it would escape the mask from the face area and that may let oxygen in keeping you alive.

I solved it by using a secondary container which holds the nitrogen and keeping it from overpressure with one way valves. Then I simply breathe from it from a hose connected to my mask.

My tread is discussing the method I plan to use.

Gas mask with reservoir, inert gas

I'm looking for advice for a variation of the inert gas method but using a military grade gas mask which is connected to a nitrogen filled environment instead. I haven’t seen this variation of inert gas proposed so I figured it was worthy its own thread I propose using this gas mask...

Hola, estoy tratando de aclararme para usar el método del nitrógeno. Como el idioma es el inglés y las traducciones no son perfectas, tengo algunas dificultades para entender lo que dicen los colegas. Por ejemplo, no entiendo por qué algunos de ustedes hablan de un depósito "puente" de nitrógeno. Cuando se deja de respirar, ¿la válvula de alivio no sigue funcionando y evita la presión sobre la mascarilla, simplemente expulsando el hidrógeno que ya no circula en los pulmones? agradeceria sus respuestas
