Why are BA Tallies Yellow

[Sparkie112]

Asked by a friend, and I didn’t know the answer. Is there any reason why BA tallies are yellow historically? Perhaps to denote type of sets? Thoughts?

Well EDBA ones are red... so why are SDBA ones yellow and EDBA red?

[Dyson]

And oxygen sets tally’s are white ….. ?

And there were green tallies many years ago

Can recall why, but perhaps on Salvus oxygen BA?

BA tallies are yellow because it denotes the set the tally belongs to contains breathable quality compressed air. Reference back to SCBA being called CABA.

But in London EDBA also contains breathable quality compressed air - but the tally is red? While ine WMFS all tallies are yellow even if set up as EDBA
