You'll learn what you need to know in your CBRN Class.
What can be said is the same that which can be said for all "commercial" gas mask filters and cartridges: They dont create oxygen. They (for the most part) are not for Fighting Fires.

Filtration systems may help to escape a fire and the use of filtering smoke hoods comes up every time there is an aircraft fire.
Source: Wikipedia, http://en.wikipedia.org/wiki/Smoke_hoodSmoke hoods present on aircraft, also called Protective Breathing Equipment (or PBEs), typically generate oxygen for approximately 30 seconds. The oxygen is kept in a closed circuit, usually thanks to a tight neck seal. A scrubber system may be present to reduce the levels of carbon dioxide, and is breathable for around 20 minutes. When the oxygen supply ends, the hood must be removed to avoid suffocation.
Jorkapp said:The cartridges are commercial/off-the-shelf, and 3M manufactures them. Googling "C7 Canister" and "C2A1 Canister" reveals plenty of information.
Here's the data sheet for the C2A1: http://www.approvedgasmasks.com/3Mc2a1bulletin.pdf
TCBF said:There are many canisters made for TICs (Toxic Industrial Chemicals) that thread to fit our masks. If the CF was called in to help with a derraillment of - say - ten or twelve 90 ton railcars of TICs, I think Brockville would fill the order fairly quickly with the right cannisters.

By the way, 3M = Minnesota Mining and Manufacturing Company.
