Hi Fellows, for example here in Perú you used the same level that you in USA, 19.5 for LL and 23.5 for UL. Eventhoug when we work in confined space we always use SCBA.
I heard that in europe they use a lower limit in the minimum limit, I not sure.

Keep safe.

Out of interest, why wear SCBA if the air is safe?

It can become unsafe and you won't know it until it is too late.

If it's a benign space, I simply see it as overkill and a complication that is not needed.

That's what atmospheric monitoring and JSA's are for.

I have to agree with Luke on this one. If the space has been preplanned, all hazards secured, and you are venting thte space why wear an SCBA? I certainly am not saying it is incorrect to wear one as I would rather an entry team error on the side of safety. But we have the tools and should haev the training to make an entry without an airsupply everytime.

If you are wearing an SCBA or SABA into every space you are assuming that a hazardous atmosphere potentially exists. That would fall into needing an NFPA Confined Space Tech making the entry. Do the folks making these entries meet this requirement?

Luke we are moved up to another station so I don't have my NIOSH guide, but even within our own country (US)NIOSH and OSHA don't agree on some of these limits. One says 35 ppm is the action level for CO, the other says 50.
