My opinion on this is that it can be included so long as you explain very carefully the circumstances when you would use it.



I do not teach using a CAT as this is not a first aid piece of equipment that they are likely to have but instead demonstrate (on myself) a bandage tightened using a pen or similar object.



Be aware of your audiences abilities! when I work in a college teaching 16-18 year olds I probably would not go there but normally my candidates are fairly sensible.



The bottom line is this: tourniquets (if used in the right circumstances) are a life saving intervention and as we are in the business of saving lives it makes no sense (to me) not to include it when teaching.



Depending on the candidates role e.g. tree surgeons I would also explain/inform them about Celox and Quickclot as well.

I tried, without success, to get a definitive answer from "our friends" at the HSE..... after much deliberation, I was told...



"The Health and Safety (First-Aid) Regulations 1981 require employers to provide adequate and appropriate equipment, facilities and personnel to ensure their employees receive immediate attention if they are injured or taken ill at work". 



I feel we are on very thin ice with this one..... I'm sure in a court of law "the wigs" would look at the VAS first aid manual as a source of reference.... there is no mention of the use of a tourniquet in it!



I concur with Marty B, it depends on your audience. I do not teach it routinely, however if I feel there is justification in its use (the potential of a catastrophic bleed) I will teach it, along with the "modified" primary survey, C - ABC.  

  

  

I was under the impression that all levels of 'clinicians' were now being taught CAcBCDE.



I will inform but not educate in this instance unless relevant as per Martys suggestion.

CAcBCDE is not universally taught in first aid. As others have said it depends on my audience as to who I teach it to.



One of the problems is that for most people a small cut to the head would look like a catastrophic Bleed.  



  

I was teaching a bunch of people who did things like tree felling and working on the land.
They asked me about tourniquets in the bleeding/wound part of the lesson. Specifically they asked if what they heard was correct - that the ambulance service carried tourniquets. So I said they did as it is now acceptable for for ECA/Techs an Paras to use them. and I moved swiftly on.... :-)

and on occasion you go waaaay off plan and teach granny knots instead of reef knots for triangular bandages.
