The Red Cross first aid advice is that gloves are considered as the "basic materials" and the mask as a "useful edition" in a first aid kit. Without argument then neither are vital to life saving.
There are two item of medical equipment in the bag; you can chose ONLY one, the gloves OR the mask.
Your DRABC drill shows you're gonna have to do CPR, which bit of kit would you chose?
The gloves (because the cabin floor of any Ryanair acft is seething mass of vomit, chewing gum and chocolate muffin?
No, the mask, because it gives you a greater level of protection than the gloves.
I think the Red Cross should revise which one is
essential.
