Talk:Self-contained self-rescue device

"a type of closed-circuit SCBA"
No, this is really inaccurate and misrepresentative in the lede.

Some SCSR are oxygen sources. But most aren't, they're scrubbers. This article needs to cover both, but this is just bad editorial writing. Andy Dingley (talk) 11:32, 17 June 2024 (UTC)


 * @Andy Dingley Do you have another source besides that NIOSH guide? That book, was written back in 1987 (with respirator regulation that isn't even in force any more), and on page 56, it (apparently?) says that "Recently, as a result of regulations promulgated under the Coal Mine Health and Safety Act, a new device of closed-circuit SCBA, known as a self-contained self-rescuer (SCSR), was certified for use in underground mines in emergency situations."Needless to say, I'm making a lot of inferences based on the way this is worded, and I'm not one for reading more Federal Register documents to check to verify this... without any leads(!)⸺RandomStaplers 07:50, 15 July 2024 (UTC)
