Method Closed circuit manual respirator kit

[Mlee75]

I am trying to research the closed circuit respirator kit and I am just becoming more confused. There is a lot of knowledge on this site that I'm hoping to tap into.
The kit includes-
A mask, an angled mask connector, and absorbent chamber with internal capsule and filler, a reservoir bag and a CO2 absorbent ( calcium lime ). Is this it? Is this all I need? Isn't calcium lime going to burn?

Yeah that's all, I guess you are talking about the Canadian Rebreather that was released on August. The manufacturer says that it has been independently tested and validated.
