I pulled one of the tabs today to see if the sheet pulls out, but instead it ran backwards and underneath and to the back of the pack on it's own. and then you remove the tab, so it looks like the ones at the back are probably broken rather than exposed.

what do you think the chance of it being nitrate based is?
